400whp S2

[audspeed]

As new on 5cyl engine, just got on 1991 S2. My goal is 400whp. Already got the DTA Stand alone system. The manifold will be custom made for T70 garrett turbo. Wastegate will be use 46mm TIAl. My main quaestion will the inatke manifold and the trotle body. These parts would be able to produce 400whp? What about the S2 intercooler? Any opinions. Thank you. Rubens at www.audspeed.com

The S2 intercooler won't be able to handle that sort of power. Most of the people on here running big power use a intercooler with a core size of 600X400X70mm AFAIK. Audiman (Tom) is running 450+ Bhp on his standard 3B inlet manifold and throttle body.

HTH,

Cheers,

T70 is too big with big lag for that targeted HP level. Even T66 is too big. Turbo Inducer cold entry size ~ 56mm will probably achiewe that targetted power level.

T70 will too big even with stand alone? What about Garrett Gt35R ballbearing turbo??? Any Idea where I can find aftermarket intercooler for 400whp set up. Help please. thanks

Pretty much most people are using these 24x12x3 IC's at the moment, there is one for sale here on ebay at the moment.

Although the same type and size are for sale by a lot of different places.......do a search on ebay.

Albert here on the forum has used a GT35R with a stand alone (I think he is now using a GT42R?), you could also speak to Javad at 034efi as he can sort you out a decent turbo, or tell you what to use.

No not necessarily, Tom (Audiman) and MartinJS here have that type of IC fitted and have retained the standard inlet manifold:

Just make a new crossmember up to support the IC. Best to make sure your choice of IC is capable of supporting your power aims and make it future proof...........you only really want to have to do this kind of job once and once only BTDT .
