hey guys i have a rev hard log style manifold for a d-series. i was wondering if the rev hard manifold is compatible with a 4 bolt t3/t4 garrett turbo. the manifold is meant for a 5 bolt turbo. some people say it should work no problem but others say that it won't because it can cause leaks and make the turbo boost late... PLEASE help me out!! do i have to buy a new manifold??

Um, the bolt pattern on the downpipe won't cause it to leak... I'm confused.

I think, but could be wrong, one of those manifolds was designed to use a four bolt turbo ( I believe, or vice versa ) and with the wrong turbo, it runs into the block.

 

Rev-Hard was similar to Inline Pro for a time, they had a cast manifold for 4 bolt exhaust turbine housings and 5 bolt. The ones for 4 bolts typically were not A/C compatable, and requred the turbo to be on the other side facing the driver fender. The 5 bolt ones were made for A/C and P/S. The best way is to show a pic and compare that to Rev-Hard's website image link . That way you know for sure.
