but does anyone have a JDM WRX intake manifold laying around that I could see if parts would fit on.

 

if things work like i hope they will i would be in the market for one. but if it doesn't then you would save me from buying one and finding out that way that it didn't fit.

Maybe you could list what you're doing and ask one of the many members if they've tried it themselves.

sounds good, i'll give it a shot to explain.

 

i have a 90 legacy and i am putting a phase 2 ej25 in it. the intake between the ej22 and the ej25 are not even close to fitting. i have heard of someone that used a 99 wrx intake manifold that used the older style IAC that is mounted to the intake and not the throttle body like the phase 2 ej25 and the ej18.

 

so my options are, use the ej25 throttle body and intake, swap TPS from the ej22 on it and live with out a IAC (which i have been doing for awhile now, just got to keep your foot on the gas when you start it up, and it's on my rally car so i really don't care to much about cold idle)

 

next would be use a ej18 throttle body on a ej25 intake and go that route. i would have the IAC from the ej18 throttle body. not totally sure if this would work because of the different styles of IAC between the ej18 and ej22, but the plugs are the same between them. don't want to really go this route because the throttle body is the smallest of them all.

 

next would be, use my ej22 throttle body on the ej25 intake and forgo the IAC, again, not the biggest problem in the world.

 

and the best combo assuming it would all work. ej22 or ej25 throttle body(which ever one is bigger, not sure yet) on a 99ish WRX intake with a ej22 IAC on the intake. so it could idle if I needed it to cold.

 

the main question is, does the JDM WRX intakes fit the the phase 2 ej25 heads. the next question would be would the ej22 IAC fit the JDM WRX intake.

 

So if that made sense that is what I am trying to do.

cool thanks i'll call him tomorrow.
