The Toyota GR Corolla is a sporty version of the Corolla. It’s built to handle rougher, faster driving better than a normal compact car, and it uses all-wheel drive. The podcast is mentioning it as one of the cars they worked on for performance testing or tuning.

Subaru BRZ
Car

Subaru BRZ

The Subaru BRZ is a small sports car made for fun handling. It’s usually set up to drive the rear wheels and feel responsive on twisty roads. The podcast mentions it alongside other performance Subarus, showing it’s part of that enthusiast lineup.

Brand

Subaru's

Subaru is a car brand that’s popular with enthusiasts. Many Subarus use a special engine layout and often come with all-wheel drive.

Concept

co-part

Copart is a place where wrecked or salvage cars get auctioned online. People use it to find cheaper cars for projects and swaps.

Chevrolet Corvette
Car

Chevrolet Corvette

The Corvette is a famous Chevy sports car. Here they’re talking about different generations—C6 and C7—because each one drives and feels a bit differently.

Concept

EJ swap

An EJ swap is when someone puts a Subaru EJ engine into a different car. People do it because the EJ engines are popular and there are lots of parts and tuning options for them.

Concept

view farming

View farming means making videos mainly to get lots of views, not necessarily because you truly care about the subject. The hosts are saying that approach can burn people out.

Concept

stance works

“Stance Works” is a car community/media brand tied to the “stance” style. That style focuses a lot on how the car looks—especially how low it sits and how the wheels fit.

Ferrari F40
Car

Ferrari F40

The Ferrari F40 is one of the most famous old-school supercars. It’s known for being fast and kind of raw, and people treat it like a collectible, so building one from random parts is a huge deal.

Concept

supercars

A supercar is a very fast, high-end sports car—usually exotic-looking and built to perform. In this conversation, it’s just part of the list of expensive dream cars.

Concept

hypercar

A hypercar is basically an even more extreme version of a supercar. It’s the kind of car that’s built for maximum performance and usually costs a lot.

RS6
Car

RS6

The Audi RS6 is a supercharged-up Audi A6 that’s built for speed, not just commuting. People like it because it’s quick and still works as a normal car.

BMW M3
Car

BMW M3

The BMW M3 is a sporty BMW that’s made to drive fast and handle well. People talk about it a lot because it’s popular with car enthusiasts. It may also come up because different owners have very different experiences with it.

Concept

building a car

They’re saying that building or modifying cars follows a similar process no matter the brand. The details change, but the overall steps and thinking are basically the same.

Term

full tear down

A full tear down is when a car (or major subsystem) is disassembled completely to inspect parts, replace worn components, and rebuild with fresh hardware. The speaker contrasts this with the broader “cycle” of how they got into cars, implying they’ve done deep builds rather than only bolt-ons.

Subaru XT6
Car

Subaru XT6

The Subaru XT6 is an older Subaru from the 1980s. The host is saying it was their first car, which is why they got into Subarus in the first place.

Cadillac XT6
Car

Cadillac XT6

The Cadillac XT6 is a larger, comfortable SUV made for carrying people and everyday driving. It’s meant to feel more “luxury” than a basic family vehicle. The podcast is mentioning it because it was the speaker’s first car.

Nissan 350Z
Car

Nissan 350Z

The Nissan 350Z is a popular sports car from the 2000s. The speaker mentions it to explain how they moved from that car to Subaru STI ownership.

Term

EJ engine

An EJ engine is Subaru’s common turbo boxer engine family used in WRX/STI cars. The host is saying they’ve owned a lot of them and never had one fail badly.

Term

EJ 33s

“EJ 33” is a bigger Subaru EJ engine setup (3.3 liters) that people use for swaps. Bigger engines often need more supporting parts and careful tuning to run right.

Term

EJ 25

“EJ 25” is Subaru’s 2.5-liter engine. Builders mention it by code because different EJ engines need different parts and tuning to work together.

STIs
Car

STIs

STI is Subaru’s performance Impreza model. Here they’re talking about STIs that were modified with a different (six-cylinder) engine instead of the stock one.

Term

full tune

A full tune is a more thorough engine software setup aimed at performance, not just getting it to run. It can make the engine work harder, which can change how long it lasts.

Term

base tune

A base tune is the first software setup that makes the engine run properly. A “full tune” usually means more performance-focused settings, so the car may be harder on the engine.

Term

Total run time

Total run time is a way of tracking how long an engine has been operating, which can be more meaningful than mileage for swapped builds that may be started, tuned, and tested repeatedly. It helps estimate wear and reliability when the car isn’t driven consistently.

Term

torque

Torque is the engine’s twisting force. Higher torque usually helps the car pull harder, especially when you’re not at the very top of the rev range.

Term

EJ based

“EJ based” means the build is built around Subaru’s EJ engine family. It’s the common starting point for many Subaru turbo builds because lots of parts and swap knowledge are available.

Term

dyno

A dyno is a testing machine that measures how much power a car makes. Instead of guessing from driving feel, it measures horsepower and torque while the engine is running.

Term

6870

“6870” is a turbocharger setup code people use in performance builds. It tells you what kind of turbo the car has, which is a big factor in how much power it can make.

Term

full tilt

“Full tilt” means the car is being pushed as hard as it’s meant to go. They’re talking about the STI at its maximum performance setting.

Term

mid to high eights

They’re using “eights” as a quick way to say the car is making numbers in the 800 range. They’re describing how strong the STI’s setup is.

Term

seven 60

“Seven 60” is a racing time shorthand—basically how quickly the car is running on the track. They’re saying their STI is in the 7.60s range right now.

Concept

keeping them alive

They mean making sure the car doesn’t break when it’s making big power. It’s about reliability, not just getting a high number once.

Concept

supers

“Supers” is slang for the Toyota Supra. They’re saying some of these cars you see for sale are built cheaply with shortcuts, which can hurt reliability.

Term

shortcuts cut

They mean people build cars cheaply by skipping the right steps. With high-power turbo setups, that can lead to parts failing sooner.

Term

wheel build

A “wheel build” means you’re building the car to make a lot of power when it’s actually turning the wheels. The cost estimate they’re giving is basically what it takes to build it for that kind of power.

Term

EJ case halves

On Subaru EJ engines, the bottom of the engine is split into two main “halves.” Builders often have those halves measured and machined so everything inside fits correctly and lasts.

Term

piston to wall clearance

It’s the small gap between the piston and the inside of the cylinder. The builder sets it so the piston doesn’t rub when it gets hot, but still seals well and uses oil correctly.

Term

bearing clearances

Bearings need a very specific “fit” with the moving parts. The right clearance lets oil lubricate properly and helps prevent wear or damage.

Term

head stud selection

Head studs are the heavy-duty bolts that clamp the cylinder head to the engine block. Picking the right ones helps keep the seal tight, especially when the engine is pushed harder.

Term

oil weight

Oil weight is basically how thick the oil is. The right thickness helps protect the engine across hot and cold conditions.

Term

11 mil head studs

This is a specific size of head stud. The point is that smaller studs may not hold the cylinder head securely enough when you’re pushing big power.

Term

half inch head studs

These are larger head studs (bigger diameter). Bigger studs can help, but they’re not a magic fix—your whole build still has to be set up correctly.

Concept

treated like a race car

The point is that if you drive the car hard like it’s on a track, it will wear out faster. To keep it healthy, you usually have to maintain it more often than a normal daily driver.

Term

E85

E85 is a gas blend with a lot of ethanol. Because it burns differently than regular gas, cars running on it often need more frequent upkeep to stay healthy.

Term

oil changes

Oil changes are when you drain old engine oil and put in fresh oil. Fresh oil helps protect the engine from wear, and with E85 you often need to change it more often because the engine tends to work harder.

Term

spark plugs

Spark plugs create the spark that lights the fuel in the engine. If you’re running a more aggressive setup, the plugs can wear out faster, so you may need to replace them sooner.

Term

wheel horsepower

Wheel horsepower is how much power the car actually delivers to the wheels. It’s measured at the tires, so it’s a more “real-world” number than engine horsepower.

Term

boost

Boost is extra pressure from a turbo or supercharger that forces more air into the engine. More air can make more power, but it also makes the engine run harder.

Term

detonate

Detonation is when the fuel-air mixture burns in an uncontrolled, violent way inside the cylinder. It can quickly damage the engine, especially when you’re running lots of boost.

Term

tuning

Tuning means setting up the engine’s computer so it runs correctly. With modified or high-boost cars, tuning is especially important to prevent dangerous conditions like detonation.

Term

wastegate

On turbo cars, a wastegate helps control how much boost the turbo makes. When boost is getting too high, it opens to let some exhaust bypass the turbo so the engine doesn’t get overwhelmed.

Brand

Haltech

Haltech is a company that makes aftermarket engine computers. Tuning with it lets you adjust how the engine runs more precisely than the stock computer in many modified builds.

Term

Mtron

Mtron is an aftermarket tuning/engine-control setup. The host is saying it’s harder to work with than the simpler “stock ECU” approach because it behaves differently.

Term

stock ECU

The ECU is the car’s main computer for the engine. “Stock ECU” means you’re using the factory computer (or its settings) instead of replacing it with a different aftermarket one.

2.5 RS
Car

2.5 RS

The Subaru 2.5 RS is a specific Impreza model. It’s usually considered a fun weekend car because it’s not a turbo and it’s built to feel lively and straightforward to drive.

Evo 8
Car

Evo 8

The Evo 8 is a Mitsubishi Lancer Evolution. It’s a turbo, all-wheel-drive car that’s popular with modders because there are lots of parts and it responds well to upgrades.

Term

F.P. Black

“F.P. Black” here is the name the speaker uses for a particular black paint/color setup on that STI. They’re basically saying the car looked best when it was still in its original black, stock form.

Term

factory BBS wheels

BBS is a well-known wheel brand. “Factory BBS wheels” means the car originally left the factory with those wheels installed, not as an aftermarket upgrade.

Term

stock body

“Stock body” means the car’s exterior is in its original, unmodified configuration—no aftermarket aero, widebody work, or major panel changes. Enthusiasts often prefer stock bodywork when they’re talking about preserving the car’s original look.

Term

pump

“Pump” means regular gas from a regular gas station. So “450 on pump” means the car made about 450 (usually horsepower) using everyday gasoline, not special race fuel.

Term

wide body

“Wide body” means the car’s fenders are widened so it can run wider tires. It’s both a visual style and a practical mod for fitment.

Term

wheel 40 50 K miles

The speaker seems to be talking about how many miles the car has been driven, but the transcript is unclear. The key idea is that the car’s real-world wear can be different depending on how it was driven and maintained.

Term

unknown maintenance

Unknown maintenance means the car’s service history isn’t documented or confirmed, so you can’t reliably know whether critical items (fluids, timing components, cooling system parts, etc.) were replaced on schedule. That uncertainty is a big deal when evaluating how healthy an engine or build really is.

Term

G the wingless GDSTI

The speaker is talking about a Subaru STI look without a rear spoiler (“wingless”). The exact STI model/generation is unclear from the transcript, but the point is the visual/trim difference.

Term

carbon fiber

Carbon fiber is a strong but lightweight material used on some car parts. People use it for weight savings and for the “race car” look.

Term

factory wing

A “factory wing” is the rear spoiler that came on the car from the factory. It can help the car stay stable at speed and it also defines the car’s original appearance.

mark seven GTI
Car

mark seven GTI

“Mark seven GTI” is the Volkswagen Golf GTI from the Mk7 generation. They’re saying their Mk7 GTI has been one of the more reliable cars they’ve owned, with only a couple minor issues.

Part

timing cover

The timing cover is a cover that protects the engine’s timing parts. If it’s leaking, it usually means an oil seal or gasket is failing, and fixing it can stop the mess and prevent bigger problems.

Term

electronics

“Electronics” here means the car’s computer systems and sensors. If they’re “rough,” it usually means the car has glitches or electrical problems that can be annoying to deal with.

Maserati Gran Turismo
Car

Maserati Gran Turismo

The Maserati GranTurismo is a luxury sports car meant for long, comfortable drives. It’s designed to feel special and drive fast, not just for short trips. The podcast is mentioning it because someone traded a car in on a GranTurismo.

Term

black box

A car’s “black box” is like a hidden recorder that saves driving data. It can show what happened—like how hard the engine was revving—so you can diagnose issues.

Term

highest RPM

RPM tells you how fast the engine is spinning. Looking at the highest RPM helps you see how hard the car was pushed during a specific drive or incident.

Term

money shifted

A “money shift” is when you accidentally shift into the wrong gear and the engine revs way too high. It’s a common way people can damage a manual car if it happens badly enough.

Concept

revert it back to stock

“Revert it back to stock” means putting the car back to the factory tune/settings. The host is saying that even after that, the dealership may still be able to tell it was modified.

Term

ECM

The ECM is the engine’s computer. When you tune the car, you’re changing what the computer does, and it can also affect what the computer records later.

Term

PID numbers

PID numbers are like labeled data points the car’s computer can report to a scan tool. The point here is that tuning can change what those scan-tool readings show, so it may not look “stock” to the dealership.

Term

warranty

Warranty is the manufacturer’s promise to pay for certain repairs. Here, the host is saying a tune can be detected, and that can lead to the warranty being denied.

Term

access port

An access port is a device that plugs into your Subaru to help tune the engine computer. It can read what the car is doing and load different tune settings.

Term

stock tune

A stock tune is the engine settings the car came with from the factory. The point here is that “going back” might still leave the car on a tune that isn’t truly the factory one.

Term

Cobb saves a version of the stock map parameters

Cobb’s tuning tools can save a copy of the factory engine settings. So when you “revert,” you might not actually be back to the exact original factory tune—you're back to a Cobb version of it.

Term

Cobb tune

A Cobb tune is engine software loaded using Cobb’s tuning tools. Even if it’s meant to feel like stock, it can still be recognized as a Cobb calibration.

Term

tuned

A “tune” is when someone adjusts the car’s computer settings so the engine runs differently. If you change those settings, the car may behave differently and could cause problems that the warranty might not cover.

Term

knock event

Engine “knock” is when the fuel-air mixture burns in an uncontrolled way inside the cylinders. It can be very damaging, so if it happens badly enough, it can hurt the engine quickly.

Term

external tune

A tune is changing the car’s computer settings. An external tune usually means a person or shop adjusts the software using specialized tools, so the engine runs differently than stock.

Term

uppipe

An uppipe is part of the exhaust system right after the turbo. People upgrade it because it can help the turbo and exhaust flow work better, especially when you’re building the car for more power.

Part

downpipe

A downpipe is part of the exhaust that connects the turbo to the rest of the exhaust. Changing it can help the turbo breathe better, which can add power—especially when you also update the engine software.

Term

intakes

Intakes are the parts that bring air into the engine. If they let more air in more easily, the turbo can work more effectively—especially when the car is tuned.

Term

E 40

E40 means a fuel mix that’s roughly 40% ethanol. Ethanol blends can let the engine run more timing/boost safely, which often makes more power than regular gas.

Term

catback

A catback is the exhaust part that starts after the catalytic converter and goes to the back of the car. People swap it to reduce restriction and change sound, usually along with a tune for best results.

Term

to the wheel

“To the wheel” means the horsepower measured at the tires on a dyno. It’s the number you actually feel at the road, and it’s typically lower than the engine’s advertised horsepower.

Term

flash tunes

Flash tunes are when you update the car’s computer software. That can make the engine run differently and produce more power without swapping many parts.

Term

91 shit

“91” is the octane rating of the gasoline. Higher octane fuel helps the engine run more aggressively without pinging/knocking, which can support more power.

Term

wheel Subaru

“Wheel” means the power reading is taken at the wheels on a dyno. It’s a real-world measurement of what the drivetrain is actually delivering to the road.

Term

reliable horsepower

They mean power that you can actually use without constantly worrying about breakdowns. It’s about building for durability, not just maximum power on paper.

Term

G 80

“G80” is the name of a Genesis model. They’re basically saying a different car platform can make it simpler to get the power they want.

Term

Subaru lever

They’re saying they strongly support something Subaru-related, but the exact phrase is unclear in the transcript. It sounds like a modding/build philosophy rather than a specific part.

Subaru 2.5 RS
Car

Subaru 2.5 RS

The Subaru 2.5 RS is a classic Subaru model that’s popular with enthusiasts. Here, the host is saying it’s designed to be kept strong and reliable when you tune it to a certain power level.

Term

600 wheel

“600 wheel” means the car makes about 600 horsepower measured at the wheels. The host is saying that number is where the build is happiest for long-term reliability.

Term

stages

“Stages” is how tuners talk about upgrade levels. Higher stages usually mean more parts and more power, and here the host is mapping what’s realistic for a street build.
