Default EJ25 Intake Interchangability

Hello,

I bought an EJ253 (99 2.5RS) long block and I need to now find an intake manifold for it. I found one (on ebay) off of a 1998 Forester w/ 2.5 engine, it looks very similar to the older ej22 intakes, with the iac on the side of the plenum near the throttle, etc.

Is there a potential that this has the same bolt pattern as my EJ253? If not, which intakes will fit the EJ253?

Won't work. There are 3 bolt patterns. Early Ej22 has one. DOHC EJ25 is another. SOHC Ej25 is the third one. You need a manifold from a 99-03 2.5RS.

Ok so I guess I'm most curious if the EJ251, 252 and 253 SOHC's all have the same intake bolt pattern.

Also curious what the variations in actual iac location are in those intakes - all built into the throttle body, or are some direct to the intake?
