well okay now, the setup, Euro Accord R engine, stock manifold. HCP mounts. Inside a 95 GSR. My question is regarding a Skunk 2 manifold. I am having problems with my idle, as the intake manifold stock, was the OBD2B IACV. It would idle great when cold, but when warm, would be very erratic. I put on the upper plenum of an older OBD1 and IACV, and now it won't idle period. So my question is, will a Skunk 2 manifold fit? I've heard and seen on their website, that they say do not use with swaps... Help please?

 

bump. any word on a venom maybe?

 

Do you mean JDM H23A vtec?

I have the very same engine, skunk2 IM will fit on all the h series vtec head.

Regarding your idle, what injectors are you running?
Could be a issue if you are running chip ecu.

also on our throttle body there is no idle adjust screw so you have to adjust the idle by slightly open or close the throttle cable bolt.

 

You are absolutely right. To correct the problem of the IACV, I replaced the upper plenum of the manifold to my older, H22A1 plenum, IACV, and corresponding throttle body. That fixed my idle, and while it was apart, I found a piece of vacuum tubing between the two plenums, causing a huge vacuum leak where the two were not seating properly. Now my big question and concern is does an aftermarket intake manifold fit?

 

IM from skunk2 or euro r will work.

but skunk2 is more aimed at top end power.

There are several threads in the prelude forum discuss about different manifold.

 

im not concerned about fitment, im concerned about it fitting in the engine bay of a swap.

 

It would help if I know what car you drive.

 

so yeah, as quoted from the first and originating post
