is z supercharged? because a 2JZ-GTE would be,
2 gen, autochoke, supercharged, performance dohc, turbocharged, efi
:dunno:

the JZ in 2JZ is the JZ engine family, usualy after the dash the "Z" would mean Supercharged

Great info post Supra_RZ!!

supra Rz is correct on that one.

oops... shouda noticed that :retard:

good post :thumbsup:

i was confused when i saw that too, then did some research to confirm it ....:smilie_da

interesting so in my 7th gen Celica I have a 2zz-ge which is 2nd generation engine in the ZZ engine family? G=Performance wide-angle DOHC E=Electronic fule injection. that awesome :) great info guys

thats awesome for new comers like me to find out engine types
i got a 1991 Camry V6-2VZ-FE

I'll stick to Honda's, there a lot easier to understand, jk great post, never new toyota had so many abbreviations for there engines

All the info seems correct, definetly a good post
