Mercedes Engine Swap King Matt Kwiek

The Mercedes E320 is part of Mercedes-Benz’s E-Class lineup, and the “320” refers to a 3.2-liter engine displacement. In this episode it’s specifically being used as a project car for a powertrain swap, which is a common restomod approach for making an older Mercedes feel more modern to drive.

A powertrain swap means replacing major drivetrain components—typically the engine and transmission, sometimes including related electronics and mounts—with a different setup. It’s a major project because it requires matching parts, wiring, and driveline geometry so the car functions correctly and drives properly.

Restomodding is the practice of updating a classic car with modern engineering, parts, and drivability improvements while keeping its original look or character. In this episode, the host frames Mercedes as a “hidden value” for restomodding because the platform can be upgraded to feel current.

“992.1” refers to the early production run of the Porsche 911’s 992 generation, and “Turbo S” is the high-output twin-turbo version. In this episode it’s mentioned as the giveaway prize, not as a technical focus.

Liz Rosenberg is identified in the episode as the host’s wife’s aunt and a Hollywood publicist. The mention is mainly biographical context for the car’s ownership story rather than an automotive technical point.

The Mercedes-Benz 190E is a compact luxury sedan from Mercedes’ older lineup, often remembered for being a solid entry point into the brand. In the podcast, it’s specifically tied to a personal story: the speaker bought one as their first car and it reportedly broke down the day after purchase. That makes it relevant to a discussion about real-world ownership and reliability expectations.

The Mercedes-Benz 300 SEL 6.3 (W109) is a classic, high-performance luxury sedan known for its large engine and strong performance for its era. The podcast frames it as part of a “life cycle” idea—luxury car in one context and taxi use in another—highlighting how the same model could be used differently depending on time and market. It’s discussed because it’s a notable example of Mercedes’ older flagship-era engineering and versatility.

The Lexus LS 400 is a late-1980s/1990s luxury sedan known for its smooth, quiet ride and reputation for long-term durability. In this segment, the host is using it as an example of a car that’s still common in certain regions years later.

“Durable” in car talk usually means the vehicle can rack up high mileage and years of use with relatively few major failures. It’s often shorthand for strong long-term reliability and the ability to keep running even when maintenance isn’t perfect.

The Pontiac Catalina is a classic American full-size car associated with the mid-century Pontiac lineup. The podcast mentions it in a casual way alongside other places or contexts, suggesting it’s being used as an example of a car that fits a certain lifestyle or setting. It’s relevant because Catalina models are often remembered for their size and era-specific character.

A manual swap is converting a car to use a manual transmission (or installing a manual transmission into a car that didn’t originally have one). It usually requires changing the transmission, shifter linkage, clutch hydraulics (or cable), pedal box, and sometimes the ECU/engine management to make everything work correctly.

BMW E36 is the 3 Series generation from the early-to-mid 1990s, known in enthusiast circles for being a popular platform for swaps and drifting builds. In this segment, it’s referenced as a chassis that a friend had multiple versions of, implying a swap-and-rebuild lifestyle.

Standalone EFI (electronic fuel injection) means using an aftermarket engine management system to control fuel delivery and ignition independently of the factory ECU. This is common in engine swaps because it lets you tune the new engine’s fueling and timing for the specific wiring, sensors, and hardware in the converted car.

The speaker is talking about how older Mercedes cars are structurally strong enough to be used as a base for other projects—“resting” or building on them. The underlying idea is that the chassis can handle the stresses of swaps and higher power without turning into a fragile foundation.

The DeLorean DMC-12 is a distinctive sports car famous for its stainless-steel body and gull-wing doors. It’s often discussed as an automotive icon because it’s unusual in design and has a strong pop-culture presence. In the podcast, it’s mentioned as one of several memorable cars people might reference when talking about specific builds or choices.

The Jeep Wrangler is a rugged off-road SUV known for its body-on-frame construction and strong aftermarket support. It’s referenced here as another example of a car that’s harder to “nail” compared with the easier-to-conceptualize builds the speaker associates with older Mercedes/Porsche-style platforms.

The Ford Bronco is a body-on-frame SUV designed for off-road use, with four-wheel-drive systems and trail-focused hardware. It’s a popular choice for people who want classic SUV styling with modern capability. The podcast mentions it as one of several recognizable “off-road” or enthusiast vehicles in the same breath as other icons.

Suspension is the system that connects the wheels to the car’s body and controls ride quality and handling. It uses components like springs, dampers, and linkages to keep the tires in contact with the road. The host mentions tweaking suspension to help older Mercedes chassis keep up on track.

Brakes are the system that slows and stops the car by converting motion into heat at the friction surfaces. On track-focused builds, brake upgrades are common because repeated hard braking can overwhelm older brake components. The host explicitly says they upgrade the brakes as part of making these cars work well again.

Bushings are rubber (or polyurethane) mounting pieces that connect suspension/control-arm parts while allowing controlled movement. They strongly affect how the car feels—soft or vague versus tight and responsive—because they influence alignment and how forces travel through the suspension. The host argues that people misdiagnose softness as needing “motorsport bushings,” when the real fix is often simply replacing worn bushings.

Spherical joints (often called ball joints in everyday terms) are suspension connections that allow movement in multiple directions with low friction. The host contrasts these with polyurethane bushings, saying the original Mercedes setup used spherical joints, so swapping in a generic poly bushing can prevent the suspension from articulating correctly. That mismatch can cause abnormal stresses and component failure.

A “five-link” rear suspension uses five control arms/links to locate the rear axle and manage camber/toe changes as the suspension moves. Because it’s a geometry-sensitive setup, the suspension needs the correct compliance and articulation at each connection. The host says that putting a standard poly bushing into the five-link can prevent proper movement and lead to snapped control arms.

Rear subframe mounts are the bushings or brackets that attach the rear subframe to the car’s body. If those mounts use softer hydraulic-style bushings, they can allow more movement under load—something that can become noticeable when powertrain swaps add torque.

Rear steer is when the rear wheels effectively change direction relative to the car’s intended path due to chassis/suspension movement. In this case, the speaker links it to softer factory hydraulic bushings allowing the rear subframe to shift under higher torque.

“Early six speed” here means the first-generation Mercedes six-speed manual gearbox design the host is referring to. The key point is that it’s described as a strong transmission architecture, and the host backs that up with real-world abuse mileage.

“Track abuse” is enthusiast slang for using a car far beyond normal street driving—hard acceleration, sustained high loads, and repeated heat cycles. It’s used to emphasize that a component (here, the gearbox) survived demanding conditions.

OEM means “original equipment manufacturer,” i.e., parts made to the same specifications as what the car came with from the factory. Using OEM clutches helps keep pedal feel and engagement characteristics closer to stock.

Uniclutch is an aftermarket clutch supplier known for custom clutch packages. Here, it’s used to build a clutch setup that can handle far more power than the stock clutch while still matching factory-like drivability.

The flywheel is the rotating component that connects the engine to the clutch. Using the “factory flywheel” means the swap keeps the original flywheel hardware, while the clutch package is tailored to handle higher torque/power.

The Mercedes-Benz CLK 430 is a V8-powered coupe/convertible from the CLK lineup, and the speaker highlights it as a “four eye” (headlight style) example. Pairing the 4.3-liter engine with a manual is presented as especially engaging and “lovely” to drive.

The Mercedes-Benz SL 55 is a performance-focused SL roadster known for strong power and a more driver-oriented feel. The speaker specifically calls out an early-2000s (’03/’04) example as “kick ass,” emphasizing how manual swaps or manual setups can wake up these cars.

The Mercedes CLK 55 is an AMG V8-powered coupe/sedan that’s prized for its blend of luxury and real-world performance. Here, the key point is that someone bought a CLK 55 with about 120,000 miles and did a manual swap quickly, turning it into a daily driver. The discussion frames it as a “factory-feeling” manual conversion rather than a hack job.

ECU stands for “engine control unit,” the computer that manages engine operation and related sensors. In an engine/transmission swap, the ECU often needs configuration so it recognizes the new setup (like a manual gearbox). This segment specifically discusses ECU generations and how easy it is to code them for a manual conversion.

A check engine light is the dashboard warning that the ECU has detected a fault or an out-of-range condition. In swap scenarios, some ECU coding changes can be done in a way that avoids drivability problems even if the light may still come on. The hosts mention that certain ECU generations are “impossible to get into,” but you may not need to fully access them if you can tolerate the warning.

In this context, “Pentium processor” refers to using an older PC/processor as part of the ECU coding/login process for the swap. The hosts are describing a workaround where you use existing hardware to access the ECU and configure it for a manual transmission. It’s not about the car’s engine internals—it’s about the tools used to reprogram the car’s electronics.

The Mercedes-Benz AMG One is a very advanced, high-tech performance car associated with Formula 1–style engineering concepts. The podcast mentions it in the context of a “manual” and references using an older “Pentium processor,” which points to the car’s complex electronics and control systems. It’s discussed because it’s an unusual, tech-heavy machine compared with typical road cars.

Naturally aspirated describes an engine that makes power without a turbocharger or supercharger, relying on atmospheric pressure and engine design. The hosts say the manual-swap setup is “pretty plug and play” as long as it’s naturally aspirated, implying forced-induction setups add complexity. That’s because supercharged/turbo engines often require more ECU calibration and supporting changes.

Supercharged means the engine uses a supercharger to force more air into the cylinders, increasing power potential. The hosts discuss why they “don’t really fuck with” supercharged setups in this context, arguing that the extra horsepower isn’t necessary for these older, lighter Mercedes. They’re contrasting forced-induction power with what the car actually needs for a satisfying driving experience.

The Honda S600 is a small, lightweight sports car from Honda’s earlier era, known for being compact and fun to drive. The podcast compares it to older Mercedes and mentions that it came with around 206 horsepower in the speaker’s example, emphasizing that it can feel more than adequate for its size. It’s discussed because it represents a lightweight performance approach rather than a big-engine luxury approach.

The Mercedes S 600 is a flagship S-Class model known for its big V12 powerplant and effortless luxury. In this segment, the host compares its factory horsepower to what can be achieved with an engine swap.

Horsepower is a measure of engine power output—how much work the engine can do over time. It’s commonly used to compare stock cars to modified builds, like engine swaps aiming for 400 or 500 hp.

The Mercedes SEC is a 2-door coupe version of the Mercedes S-Class, typically associated with powerful V8/V12-era engines depending on generation. In this segment, “Sean’s Black SEC” is used as an example of a swapped/modified car that can light up the tires under hard acceleration.

Angeles Crest refers to the Angeles Crest Highway area in Southern California, known for steep grades and winding roads. It’s a popular local route for testing how a car accelerates, brakes, and holds traction in real-world conditions.

“Pagoda” is an enthusiast nickname for the Mercedes-Benz W113 SL, named for its distinctive, pagoda-like roof shape. In this segment, it’s specifically tied to an engine swap using an M113.

The Sunbeam Tiger is a classic British sports car known for its lightweight feel and (in most versions) a Ford V8 swap heritage. The host uses it as a comparison point, implying the modified Mercedes “Pagoda” ends up with a similar character—small, lively, and V8-powered.

Bring a Trailer is an online auction site focused on enthusiast cars. The host’s mention suggests the modified car is being sold through that community marketplace.

“5.4” here refers to a 5.4-liter engine displacement, commonly associated with Ford’s 5.4L V8 family in swap builds. It’s mentioned alongside a 6-speed and a rear-end setup, indicating the specific powertrain combination in the car.

The Overcrest rally is an enthusiast driving event referenced as part of how the host used the car. It signals the car was driven hard enough to be part of multi-car/multi-route outings rather than just stored.

“Amelia” most likely refers to Amelia Island Concours d’Elegance, a major classic-car event in Florida. The host’s mention implies the car was driven to a high-profile show, not just trailered.

The Ferrari 360 is a mid-engine V8 supercar from Ferrari, known for its compact layout and enthusiast-friendly “swap culture” compared with more modern cars. The host mentions doing a manual swap on a Ferrari 360, which highlights how some cars can be converted with the right parts and electronics work.

“Mercedes star diagnostic system” refers to Mercedes-Benz’s factory diagnostic tooling (often associated with the STAR system) used to communicate with the vehicle’s ECUs for coding, troubleshooting, and parameter changes. Swap work frequently depends on having the right diagnostic interface to properly program the car.

The Mercedes Crossfire is a niche late-1990s/early-2000s coupe where the shifter feel and reverse behavior are tied to the gearbox design. In this segment, the key issue is that the older setup lacks an internal reverse lockout in the transmission, so the reverse lockout is handled by the shifter itself.

An internal reverse lockout is a transmission feature that prevents selecting reverse unless the shifter/transmission logic allows it. When it’s not internal, reverse lockout depends on the shifter mechanism, which can lead to poor feel or reliability issues. In this segment, that’s why the newer transmission design is preferred.

A short shifter is an aftermarket shifter linkage designed to reduce the lever’s travel between gears. Shorter travel can make shifting feel quicker and more precise, especially when paired with a transmission that has the correct reverse-lockout behavior. In this segment, they mention short shifters as a way to improve the older Mercedes setup.

The Mercedes-Benz E-Class is a mid-to-large luxury sedan that sits below the S-Class in the lineup. The podcast specifically references late-60s to mid-70s E-Class models and mentions engine variants like the “300” as part of a discussion about which chassis/years to consider. It’s discussed because older E-Class cars are often sought after for their classic design and Mercedes engineering.

The Mercedes 300 D is a diesel model from the early “E-Class” lineage the speaker describes as a precursor to the later 123-era E-Class. The key swap-related detail is that these cars share underpinnings with the Mercedes 107 SL, but their engine-bay frame rails are narrower, preventing a V8 from fitting. That physical constraint is why certain swaps are impractical.

The Mercedes 107 SL (1972–1989) is a classic SL generation that the speaker uses as a reference point for chassis/underbody similarities. Even though the 300 D/220 D cars share the same general foundation, the engine-bay frame rails are narrower in the diesel cars, so a V8 swap isn’t physically possible without major changes. The takeaway is that fitment constraints drive swap feasibility.

Common rail is a diesel fuel-injection system where high-pressure fuel is stored in a shared “rail” and delivered to injectors as needed. The speaker mentions it in the context of modern diesel swaps, implying better drivability and efficiency compared with older diesel injection approaches. They connect it to the OM648 engine they name next.

OM648 is a Mercedes-Benz diesel engine (an inline-six) referenced here as a “common rail” option for modernizing a diesel swap. The speaker calls these engines “fantastic,” suggesting they’re a strong choice when you want the benefits of newer diesel technology while still staying within feasible swap packaging. It’s part of a broader discussion of diesel swap pathways.

CDI is Mercedes-Benz’s branding for diesel direct injection. In the segment, the speaker connects CDI to a specific model/engine context (“C320 CDI”), reinforcing that the swap discussion is centered on diesel direct-injection powertrains rather than gasoline V8s. It’s essentially shorthand for a particular diesel fuel-delivery approach.

The Mercedes C320 CDI is a diesel-powered C-Class variant used here as an example of a CDI (diesel direct injection) engine. The speaker’s point is that these diesel engines can still be worked with in swap projects, even if the goal isn’t fitting a V8. It’s part of the “what can you do instead?” discussion for older chassis constraints.

A limited-slip differential (often shortened to LSD) helps transfer torque to the wheel with more grip when one wheel starts to slip. That makes a car more usable in real-world driving—especially on wet roads or when accelerating out of corners.

The Mercedes 450 SCL 6.9 is a late-1960s/early-1970s Mercedes-Benz sedan known for its big V8 and luxury performance. The speaker mentions it as one of the Mercedes models that used a limited-slip differential up to around 2000.

The Mercedes 500e is a performance-oriented Mercedes-Benz sedan from the 1990s that’s famous for blending luxury with serious power. The speaker notes that some 500e versions were available with a limited-slip differential.

LSD stands for limited-slip differential. In this discussion, the speaker contrasts a hydraulically actuated setup (ASD) with a clutch-style LSD that uses wheel-speed sensors plus a hydraulic system to engage the locking action.

ASD here refers to a hydraulically actuated limited-slip differential. Instead of using clutch packs directly in the same way as some LSD designs, the hydraulic system helps control the locking behavior.

Brake vectoring is a traction-control strategy that uses the brakes on individual wheels to help steer the car and manage slip. The speaker is saying it’s not the same thing as the clutch-style LSD they’re describing.

The Ford Mustang is a long-running American sports coupe/convertible known for its performance heritage and wide range of powertrains. The podcast mentions the Mustang in the context of drivetrain behavior—specifically how a differential can be actuated or locked—suggesting a discussion about traction and mechanical features. It’s a natural topic when talking about modern performance cars and how they handle power to the wheels.

The Mercedes-Benz G55 (here, a 2003 example) is a high-performance variant of the G-Class, known for its rugged, boxy off-road chassis and V8 power. In this segment, it’s notable because the host describes swapping in a manual transmission and keeping the transfer case functionality so it can be used off-road.

A transfer case is the gearbox that splits power from the transmission to the front and rear axles in a four-wheel-drive vehicle. In this swap story, the key point is whether the transfer case still works after combining components from different drivetrains.

“Divorce transfer case” is an enthusiast term for a transfer case arrangement where the transfer case is separated (“divorced”) from the transmission assembly, often using a different mounting and driveline layout. In swaps, it matters because it affects how the driveshafts and linkages must be adapted to make everything fit and function.

The G-Class (often called the G-Wagen) is a boxy, rugged Mercedes-Benz SUV known for its off-road durability and classic design. The podcast specifically mentions having a manual G-Class and that the transfer cases work, which highlights its mechanical, off-road-oriented nature. It’s discussed because it’s a distinctive vehicle that’s built to handle tough terrain while still being a recognizable luxury SUV.

Lockers are differential locking mechanisms that force a wheel pair to rotate together, improving traction when one wheel loses grip. The speaker mentions that the lockers “work,” which is important for off-roading in snow and low-traction conditions.

OM606 is a Mercedes-Benz inline-six turbo-diesel engine family (often associated with the late-1990s E-Class), known for its durability and strong low-end torque. In the segment, the host uses it as a reference point for what drivetrain they swapped into a truck, and then starts describing its architecture.

Indirect injection is a diesel fuel system design where fuel is injected into a pre-chamber (or similar auxiliary space) before it enters the main combustion chamber. It typically changes combustion characteristics versus modern direct injection, and it’s part of how the OM606’s diesel operation is being described.

A “P pump” refers to the Bosch inline diesel fuel injection pump design used on many Cummins engines. It meters fuel precisely for each cylinder and is known for durability, which is why people describe them as “bulletproof.”

A mechanical injection pump uses engine-driven mechanical linkages (rather than electronics) to meter and deliver diesel fuel. “Backdating” to it usually means converting a more modern setup to an older, simpler control strategy.

The Ford F-250 “Highboy” is a classic 1970s heavy-duty pickup known for its tall stance and off-road-friendly proportions. In this context, it’s the truck that received a Cummins-style diesel injection setup, showing how these swaps can turn an old Ford into a modern-feeling diesel workhorse.

The Ford Falcon is a mid-size car platform that became a popular base for engine swaps because it’s relatively simple to modify. In the segment, the host describes swapping in a Mercedes diesel into a Falcon, which is a standout “why would you do that?” build.

The Mercedes OM606 is a diesel engine family (a 3.0L inline-six) that’s popular with swap builders because it’s compact and robust. Here it’s used as the donor engine for a Mercedes-diesel conversion into a Ford Falcon.

A “dog leg” five-speed is a manual transmission layout where the shift pattern has the first gear positioned down and to the left (often with a more race-like feel). It’s commonly associated with certain older performance transmissions and is sought for the way it changes driving feel.

“Diesel gate” refers to the emissions-cheating scandal that came to light in the early 2010s, where some diesel vehicles were programmed to behave differently during testing. It changed how people viewed diesel technology and led to heavy scrutiny and regulation.

“Rolling coal” describes intentionally modifying a diesel to produce excessive black smoke under acceleration. It’s usually done by increasing fueling beyond what the engine would normally deliver, often at the expense of emissions compliance and sometimes engine longevity.

M119 is Mercedes-Benz’s internal engine designation for a V8 used in certain late-1990s performance models. The host calls it a “fantastic engine,” implying it’s a desirable swap candidate, even if this particular shop build isn’t using it.

The Mercedes-Benz M113 is a V8 engine family known for being relatively straightforward to adapt for swaps, including pairing with a manual transmission. In this segment, the host points out it can accept a manual “bolt-on,” which makes it a popular starting point for engine swaps.

The Mercedes-Benz 500 e is a high-performance W124-based model that’s used in this segment as the swap platform. The host describes ripping out an M119 and installing an M156, then pairing it with a manual—highlighting how drivetrain choice and packaging drive how feasible a swap is.

The Mercedes-Benz 400 e is a W124-era performance sedan that’s relevant here because its engine bay dimensions differ from the car the host is swapping into. That difference is part of why the M119 swap would require major changes like firewall and cross-member work.

The Mercedes-Benz M156 is an AMG-developed 6.2-liter V8 known for its quad-cam (four-cam) valvetrain layout. In this segment, the host calls it the “spiritual successor” to the earlier Mercedes V8s and describes swapping it into a 500 e with a manual transmission.

“Quad cam” refers to a four-cam valvetrain design, typically meaning two camshafts per cylinder bank (four total) controlling the intake and exhaust valves. The host uses it to describe the M156’s valvetrain architecture and why it feels like a next-generation Mercedes V8.

“RPM” (revolutions per minute) is a measure of engine speed, and “revs to 7,000 rpm” describes how high the engine can spin under load. The host contrasts that with daily-driver needs, implying that a high-revving engine can feel less relaxed in stop-and-go driving.

A “5-speed” refers to a manual or automated gearbox with five forward gear ratios. Here, the host is talking about the transmission choice for a daily-driver cruiser, specifically mentioning a five-speed as part of the plan.

A conductor plate is the electronics/control layer mounted on top of a transmission’s valve body. It carries solenoids and sensors and routes signals to control shifting. When it (or related sensor connections) fails, the transmission can lose key inputs and fall back to limited behavior.

Electronically controlled transmissions use sensors and solenoids managed by a transmission control unit to command shifts. The electronics depend on reliable signals like speed sensing. If sensors crack or lose signal, the transmission may not shift normally and can get stuck in a default gear.

The valve body is the hydraulic control “manifold” inside an automatic transmission that directs pressurized fluid to clutches and bands. Even in electronically controlled transmissions, the valve body still does the hydraulic work. Electronic components (like solenoids on the conductor plate) command the valve body’s fluid routing.

Solenoids are electrically actuated valves that open and close to control hydraulic flow inside the transmission. In electronically controlled automatics, solenoids translate electrical commands into fluid pressure changes that trigger gear shifts. If the control plate or wiring/sensors fail, solenoid control can become unreliable.
