Ive had my S for about 15k miles and have been through 2 manifolds. Both have been from Greddy, the cast iron one and and the stainless steel; both cracked in the same exact spot. The stainless steel one Ive had on there for 5k miles of that. I dont know what to do at this point. Ive noticed since Ive installed the stage three clutch theres been a lot more vibration coming back through the trans and the pumpkin in the back almost like the whole car is shaking. Ive been think of getting the Innovative motormounts or something, this may have attributed to the manifold cracking(engine flex). Im only pushin 10 psi so thats about 300hp to the wheels. I really need some feedback on what to do here, i cant keep going through manifolds like this.. So I guess I hve two questions. How do I take care of this vibration (especially on launch 1st) and what am I suppose to do with this turbo kit and cracked manifolds?

 

greddy manifolds seem to be crap. my buddy has gone through a few as well. PFab makes a replacement manifold for the greddy with a lifetime warranty and great quality.

just throwing my 2cents

 

Thanks, Ive heard some good things about them.. I like that 1151 btw, i was driving those things not even a year ago out the gates of Adder..

 

good times i bet... it was 08' i had an m1114 at first but it would start anymore so my command hooked me up with a fresh m1151 with plastic still on the seats! didnt last long with me tho.. road collapsed lol

GL with the manifold btw

 

Does Greddy replace the faulty manifold for free?

 

PFab is good stuff

 

^^^^ they should^^^
But why would you go with something that continuously fails?

Dont try to fix another issue to correct the one you have.

 

ebay has pfab manifolds for like 300 but if you bid on a new one i believe you can get one for around 200 shipped
