Have any of you ever heard of a (not OUTRAGEOUSLY expensive) turbo kit for this car? It's obviously got a 3UZ-fe v8 and I want a little more kick. I've got a catback exhaust and an injen intake on it already. Suggestions?

 

Your better off getting a supercharger as kits are a little more available and easier to setup.

Currently there are not any turbo kits available for the 3uzfe. It will be custom and the only one that exists (as far as I know in the US) now resides in Texas.

Look into pro-charger, universal kits that can yield good numbers with the right tuning.

 

Actually this company offers a twin turbo kit for the 3UZ but I dont think it comes with a fuel management or intercoolers.

I've seen that many a time and my number one question every time I see that is what kind of tranny would you run with that? Surely, the stock 5-speed (01-03) would not be able to withstand 700whp.

 

please note they are advertising a "built" 2UZ-fe meaning the internals are changed out with beefier parts - the stock internals of the 2UZ and 3UZ cannot handle that kind of power - the Rod beams and main Journals are waay too thin.

 

It is very possible to put a supercharger on an ls430.
I currently have an rmm supercharger in my gs430 and it is awesome. Same engine essentially would work just fine. The only thing I see that would probably have to be changes is the intercooler piping and that is fairly easy to have done.
