Hi, I got some more questions to ask on my on going quest to gain ultimate knowledge and become the chosen one............ errrr yeah right :conf:

 

basically, I'm gonna be getting a Supra pretty soon, and its most likely going to be an Auto. Now how much BHP can the auto boxes take before any serious mods need doing to them, I've read they can handle up to 380BHP with just running different grade CVT oil?!?!? is this true HELP!!!

 

Also I know the UK spec comes with steel turbos as standard, and the J spec have ceramic, what was the reason for this and are there any advantages for either?!?!?! I assumed it was because the UK spec has 330BHP, large throttle body and injectors etc as standard, but like i say i'm not 100% on this!!

 

well if you can shed some light on these points that would be cool!

 

cheers guys

Hi,

 

I believe the auto boxes can take much more than 380 BHP, and you don't need to change the oil. Just keep the standard Toyota oil; in fact, you can damage the gearbox by using incorrect fluids.

 

Ceramic turbos spin up a little quicker, so may be give fractionally better acceleration, but are more fragile, i.e. more likely to break when increased strain from more boost is applied. Steel turbo blades can take a higher boost pressure.

Hi Paul, so the Auto boxes should be able to take more BHP then, thats good because I just wanted to know for sure really because engine mods are alway a possible thing incase i ever get the need for more ponies under the bonnet :D

 

and as for the turbos I the steels ones are heavier like you day as I've just been reading some other threads too

 

hmmmmmm I think that gives me more to think about now!! cheers

 

all i got to do now is find the right car!! :confused:

 

I've been for a few test drives now and every time i get back i've got a grin from ear to ear!!! just cant wait to have my own!! ahahah

 

cheers
