I know, i know, im an idiot but can it be done? Is there some magical chance that the CA18ET exhaust manifold fits on the Z20?? I just bought the entire turbo set up from a ca18et off of ebay without thinking about logistics (it was cheap ok) and I need it to go on a Z20. I know its a 99% chance the bolt pattern is different but maybe someone out there has done it with minor modification? Any help would be greatly appreciated.

Z18 should be like the Z20...

This KA24 has a Z18 manifold fitted.





Nothing like a CA18 manifold..Not even close enough that you could modify it. If it was on an offroad buggy, you could make up an interface manifold. But that's a heap of work.

A Z18 manifold has a T3 flange not T2 flange like the CA18 and SR20.

z18 bolts onto Ka24e but the ports dont line up.

As dattodude said I would assume z18 would be fine on the z20, but theres no garantee that if it bolts up the ports would line up.

Cheers,

Richard
