home made turbo kit?

Right now another big turbo company and myself are working together to build a turbo kit for the P5. It'll be an all 304 stainless steel header setup for an external wastegate...
Next week the header flanges will be cut.Hopefully we will have the header complete in the next month or 2.

coo, keep us posted.. do u have any ball park prices for a manifold, or its just a full kit?

The manifold will be avaliable seperate.For an all stainless uncoated it look's like it will be in the $500-$600 range, don't quote me on that though.
 
EWWWWWW 304 stainless on teh EGT's we are running means crackity crack crack on teh mani...I would serioulsy consider changing that to 321 SS I knwo its more but you won't have the complains of cracking manifolds like you will with 304

Alot of the cracking comes from using the wrong rod when welding primaries to the flange and not back gauging it.

I am aware of the cost of 321 but the cracking in 304 with turbo applications is not the weld as i have welded many many 304 manifold cause people wanted that due to cost and used the correct rod TIG welded the heat makes the heat cycle of 304 SS SUCKS and the metal is way too brittle even with a porperly designed manifold it will still crack....if you decide to use 304 i would not put a warrenty on the 304 manifold against cracking unless you are using some really thick gauge steel or some really beefy supports.
