Hey guys, sorry to be bothersome, but i have some questions. Im about to buy a pettit subframe, does it take care of the bump steer problem? Also can i use stock oil pan with that subframe.

 

Also how bad are the stock turbos? What is needed to get them to perform to get me to about 350-400hp tops.. Thats where im gona be happy with.. with all that tq.. lol

 

You will be able to use the stock oil pan with the subframe. You will also need to get the new spindles to help correct the bump steer. Lastly the stock twins will easily give those hp figures, but they will guickly run out of breath in the upper rpm's.

 

Also here's a dyno gragh of the stock twins on a stock rebuild 20b(no porting) :

These runs were done with 10psi & 15psi boost.

The owner of this vehicle has over 40k miles with this set-up and has been very reliable.

 

Thanks so much tvon! Is there any websites with good info on the swap or any install guides to help with stuff?

there is a nice list of parts and swap info out there but i cant find that link now

 

The only thing that is needed is a good boost controller and a good engine management system...two things you're going to get anyway. I'm getting 427 hp with a stock motor, stock turbos, Apexi AVC-R and twin Electromotive Tec-II's.
