Default Intake and Exhaust Swaps...

Does anybody know if the manifolds from a 2.0 and 2.5 are interchangable?

What about headers will the same headers fit a WRX and an STI and are the STI headers the same as an rs?

Any info would be helpful

Default fits?

I'm pretty damn sure Subaru has kept the same Measurements from exaust port to exhaust port. So I think all the ej series headers should be interchangeable. I know I can use iether WRX or STI headers on my 98 DOHC ej25. But the SOHC MIGHT be different.Anyone use WRX headers on thier GC8 SOHC ?

I think intake manifolds will fit all ej as well. But If I'm wrong dont kill me. I know I can use the ej22 SOHC on my 98 DOHC.

generaly its all interchangable except:

1. Single Port vs Dual port heads, obviously they wont match up.
2. Turbo vs Non Turbo crossmembers, A turbo header will run into the Xmember of a non turbo car, and visa versa. The Xmember has to match the header.
