i have pe-tt and I'm going to install them with in the next 2 weeks or so.

i heard roamers that the manifold do crack after you boost more than 1-bar ?

i need to know if that true or not, so i can custom my own stainless steel manifold

 

Do you have the older header style manifolds? or the newer style cast iron?

I've herd under extreme heat the welds come apart (header style).. I've only herd of 1 or 2 cases on this board. My shop has done a bunch of the header style kits with no problems...

If you have the old style, you can buy the new cast ones from PE...

By the way, nice kit, what are you going to use for engine control?

 

They can crack but it isn't necessarily related to what boost you are running. Stainless steel manifolds just don't last as long as cast iron. If they are the cast then I wouldn't worry about it.

 

===================================

i have the old-style, so how will that work?
i know all about pe-tt cast manifold but the problem it cost 1600 for pair

the engine control am using is TEC3.

also,what i do know is that, the cast manifold don't last as long as the stainless stile manifold 302? i might be wrong but that what my custom shop tolled me?
