If you are trying to find an Intake manifold there are many different manufactures and I doubt you are even close at needing an aftermarket one. The 1g/VR-4 Intake manifold can push out 400hp easy without chocking. You only get one if you are trying to squeeze out more or every little bit of power possible.

As far as for the exhaust manifold, if you have the OEM still they tend to crack over a long time. You can upgrade it to a 2g exhaust manifold but will need to grind down one of the corners near the PS pump. You can spend a bit more and get an EvoIII exhaust manifold or an FP.

Tunersnation has bolt on exhaust in a few different styles. Not many intakes are straight bolt on unless you can find an amg. Or cyclone intake but even the cyclone requires some tinkering to get it working properly. But like stated before you don't need an intake mani yet. As far as exhaust mani the best options have been stated.

You aren't exactly clear on what you are trying to acheive, is it performance or looks? More noise? If you aren't looking to make any more power,the stock stuff will do. /ubbthreads/images/graemlins/wink.gif

By "intake manifold",do you mean the intake pipe before the turbo,or the actual intake manifold that bolts to the head?

By "exhaust", do you mean the downpipe/cat/pipes/muffler,or the manifold that bolts to the head?

SO you just need to REPLACE your current manifolds?

Stock manifolds can be found on other:

1991-1994 Mitubishi Eclipse Turbo (GST & GSX models)
1991-1994 Eagle Talon Turbo models
1991-1994 Plymouth Laser Turbo models

exhaust manifold can be bought from rockauto.com direct fit, no grinding etc, intake manifold may be on their site as well, but replacing the intake manifold is not a common thing so maybe not.

Why are you replacing these manifolds?

That's the problem,you need to put it a little less simple. You may be able to deciper what you meant,but judging by the replies you initially got,obviously no one realized that you were looking for stock replacement parts either!

Like mentioned before the 2gen ('95-up)style manifolds are the next closest replacement to the '90-'94 1g style/original part. It has a 6cm collector opening to match the stock 14b exhaust housing (The EVO III is otherwise similar but with 7cm matching a 16g). You still can get the them from Mitustishi through JNZ if having factory parts matters. IIRC,the heat shield is different between them and the '90-94 versions.

The cast those manifolds are made of seems to grind easily. If you were to source one used or new cheap,or just want to upgrade (they don't crack as easily),I wouldn't let that be a deal breaker.


The only replacement intake manifold without not requiring any modification to work as it's intended is the stock manifold,turbo or non turbo. I'm not aware of anything that would go wrong with it to need replacement,and even if you decide to mod the car later guys have gone 10's with them at least so it should be good for a while.

thank you and everyone else for there input.
I really appreciate the input and I am sorry for not making myself more clear in the original post.
I just wanted to know what to look at in case I had issues with the current stock parts that are on the car.
