Default K20 type R exhuast manifold fits K20a3 (EP3 SI) engine?

Just wondering if this works?

And also what is the going rate for a k20 ITR exhuast manifold, thanks

Does not fit for the exact same reasons as the RSX type S exhaust manifold does not fit. The flanges on the two exhaust manifolds are different in where the manifold lines up with the bolts on the head.

Did you have to do anything more to the manifold to get it to match right?

This may or maynot apply to the Ep3 but to be able to use the manifold on a base RSX requires you either modify your existing exhuast or get an S exhuast . The headbolts are the same. Kinda like on the b-series motors, where you can use a header for a b18c1 on a b18b with some exhuast shortening/extending depending on the car.

remember you'll need the electronics to go with the K24 intake mani if you wish to retain the butterflies............

It's cool, I'm fitting a K24 into mine but I gotta source a K20 head from the US (somewhere????) so I wanna make the intake and exhaust manifolds off the K24 head and then fit the K20 head and then I'm good to go
