aight guys i just swapped a b20 into my EG hatch..the thing is i used to have an LS in it and ended up reusing the same intake manifold because the crv one is way too big...

the question is how do i route the fast idle because on the crv intake manifold the fast idle seems to be attatched to the throttle body and and somehow ties into the IACV for coolant...but on the LS the fast idle is attatched directly to the intake manifold and redirects back to the block...now my problem is im using the LS manifold, throttle body and fast idle and there is no return nipple for the fast idle on the b20 block like there was on the LS one

 

pretty confusing.. but i used a ls tb and manifold.. i think i know what u talking about though.i had to rig that somehow.. i prolly check later.

 

I have the same swap. You probably have the B18A ls intake manifold. Get the B18B ls intake manifold where the fast idle valve is attached to the TB just like the B20's.

 

yeah ill try to make some calls i think i know a few people with some LS manifolds
