Hi All,

I am looking at upgrading the turbos from the JDM to the USA ones.
Has anyone here done this?
Any information would be appreciated.

Thanks

We're all NA here in the USA.

he probably wants to upgrade to the supra turbos, which is the engine in the aristo.....

don't waste your time... it won't be cheap and would hardly be worth the effort.
you'd need all USDM parts... turbo, exaust manifold, injectors, cams, etc...
just to have a minor top end gain and a slower spool up..

i imported a clip of a JDM ARISTO...
swaped out intake manifold, exaust manifold, & fuel system..
JDM cams are probably gonna be my limiting factor.

So the Supra turbos are bigger than the Aristo ones? I didn't know that.

Well i guess no one has done it then.
The JDM turbos give 15% greater flow then the aristo ones and the US ones give 15% more then the JDM.
So thats a 30% gain in power so it is worth it.
Currently have 240RWKW at 15psi that should increase to 280-290RWKW on same psi.
They bolt straight in and would just need to change to larger injectors and modify exhuast.
I will keep you guys informed of progress.

Cheers
Al.

JDM supra & JDM aristo are the same turbo i'm pretty sure..
USDM turbo's flow a bit more...
