Correct. Japan 2JZ CT20A, US 2JZ CT12B

[Norbie]

So do any of them say ct 12 b or ct 20 b on them. all the ones ive seen just say toyota.

Mine have CT20A on the compressor housings, but most others I've seen just have Toyota. I'm not sure why the difference, but according to the Toyota EPC they all have the same part number.

Norbie to the rescue cheers dude, i was wondering the same question

+ve for you

this is a bit of a "how long is a peice of string question"
What sort of grunt are people getting out of 2JZ's with a bar of boost and bolt ons such as exhaust and bigger FMIC?

About 230rwkw. 1bar is just above the boost cut point so youll need an FCD of some type to run this.

Max Ive seen is 300rwkw on JDM stock turbos (yes I mean stock, not hiflowed or steel wheeled)

241rwkw through and auto is what I have. And yes the turbos are definitely ceramic.

Youre running more than 1bar though arent you??

[MR 1JZ]

hmmm ok

good food for thought, naturally I am enquiring in regards to my aristo..so its auto as well

thanks for that people

[MR 1JZ]

also how the hell do you get 300rwkw from stock turbos?

wouildnt they just fall apart?

I am on the street in cold weather and long ramp rates (high gears). I wish I had a boost readout on the dyno that day but I bet it would have been around 15 psi 16psi tops with the heat and short ramp rate.

They lasted quite a while. The guy is now doing a big single swap and I dont think hes doing it cos his twins died. Yes it is crazy but he has dyno slips and trap times to back it up.

His name is Thadius on supraforums.com.au

[MR 1JZ]

phuck me thats insane....is he sure they were cearmic??

[2JZR31]

This guy also claims he ran 135mph on a standard 2JZ with stock turbos with usual mild upgrades. 135mph is good for a high 9 second pass and equates to around 620hp in a car of that weight. I am more than skeptical...

I have also seen 300rwkw. Southo on PF recorded one or two KW under the triple ton through an auto. (stock ecu usual basic mods, but with an accidental massive boost spike above 20psi) Even with the boost spike I am skeptical this reading was a true reflection that can be used as a comparison. Dyno readings are almost pointless for comparisons unless the same cars are compared on the same dyno on the same day.

im not skeptical, i say hes full of shit.

not time slip to back it up, there is no way in hell it ran 135mph trap speed on stock twins, not without about a 100 shot of gas.

747 to put it bluntly, yep
