Thread: RWD exhaust manifold?

I'll probably get flamed for this one...

I thought I read somewhere that it would be feasible to use a turbo manifold from an SR20DET on an SR20VE. In other words, the flanges for the exhaust side are either the same or so near it makes no difference.


I did a quick search and haven't found the answer yet. I'm also not home to mock up parts.

The reason I ask is because I found a great deal for a twin scroll mani that was built for the DET. I wanted to use this for my RWD VET build.

Anyone with experience? Thanks.

Depends on how it was set up, if it places the compressor housing towards the front of the motor instead of facing towards the rear then more than likely it will fit and work. Same goes for the other way around.

The exhaust flanges are the same but the ve ports are slightly higher so you would have to oblong the holes and lift the manifold up or just port match them by opening up the ve exhaust ports more and porting the flange to match as well. Most people just oblong the holes and lift it till it lines up.

EDIT: I missed the part about him wanting to use this for an RWD VET setup.

You mean towards the rear, front of the motor is the side with the pulleys, rear is the flywheel side. If it's placed towards the front then you will have a hard time getting the downpipe on without hitting the coolant hose, Alternator and AC compressor.




Though be careful, some RWD flanges might not be as forgiving like mine is.




How much to be removed on all flanges:

Reading owns you Vadim. He is looking for a RWD manifold setup, lol. But the one advertised is for a fwd det. But there are some custom manifolds for the fwd's that put the compressor on the front side of the motor instead of the back side. If done properly you will have way more clearance for a downpipe than trying to clear your alternator and a/c if you still have it. Your coolant hose doesnt come anywhere near that close.

Anyways if the manifold was built to put the compressor towards the rear then it wont work on the rwd's as the flange is alot further away from the head and you wont be able to put the turbo on without hitting your strut tower, BMC and other things.

Yup I fail, guess I'm just used to FWD guys posting up asking about RWD manifolds

Thanks guys. I appreciate the feedback. I also forgot to mention the manifold I was looking at was made for the RWD DET. So I'd say that takes some of the guess work out of the equation.

I'll ask the guy to take more pics of the flange itself to see how much clearance I would have for port matching.

Which ever way you go, you definitely want to make sure you don't have any direct restrictions. With VE's high cam's high overlap it will eat some ponies .
