Are there no tuning options for the factory 2JZ ECU? The TJ manual transmission (AX-15) is essentially the same thing as a Toyota R154, so it should hold the power.

Once again, a perfect candidate for a 1UZ swap!

Yeah, but I don’t spend thousands of hours sitting inside my iPhone. What if I don’t want the default interior color, seat material, etc...? If I’m buying a new car, I want the one I want.

I wonder if it’s related to the cart/irl V8 that spawned the LS400 1UZ V8

I don’t call changing almost everything on the car a “few mods”.

Agreed. This car is trashed

I really don’t understand how you could possibly call this car clean and unmolested.

Did you really just use “silky smooth” in the same sentence as a 5.9 Cummins? Those engines are anything but smooth. Same goes for the Jeep 4.0 and Ford 300 for that matter.

The supercharger feeds the turbo in this application. It’s not necessarily the volume of air that matters, but the mass of air. The blower is still passing 400 RWHP worth of air-mass through it.

Look at the other video. Supercharger feeds the turbo.

1JZ is down on displacement compared to a 2JZ, so it’s harder for it to spool a big turbo. Making it laggy on the bottom end. Supercharger provides boost until the turbo gets going.

The supercharger feeds the turbo, which is then aftercooled. So no, there isn’t any more chance of heat soak. Also high intake temperatures do not cause a lean condition. They increase the chance of knock.

That M90 cannot be happy pushing 400 RWHP of air through it. That’s way above what those things top out before they just start heating the air uncontrollably.

It’s covering the injectors, which are typically very loud. Especially in GDI applications.

...and that switch and how it functions is described to the EPA.

The PCM, air-intake, etc...are all street legal, emissions certified and do not affect the warranty. Chrysler may have some internal regulations about selling a car that can run on “race fuel” - or they may just be doing it for safety, just in case NHTSA or the EPA could possibly object to it.

It’s an option package that comes with the car, and is still all street legal and emissions certified.

I give a lot of credit to these NASCAR engine builders that can keep 2-Valve OHV valvetrains together for extended periods of time at ~9,000 RPM. Valvetrain issues like that are one of the main reasons why most modern high-RPM engines switched to 4 valve DOHC cylinder heads.

These stunts are just insulting to anyone who has an introductory college physics course under their belt. You’re towing something with wheels over flat ground.

Inherent balance doesn’t mean the engine is vibration free or smoother running. Toyota/Lexus’s 1UZ V8 was quantitatively smoother running than comparable BMW and Mercedes “naturally balanced” I6 engines.
