I'm doing an h23a swap on my eg does anyone know what intake manifold and harness I need , I just moved to Indianapolis and I have very little knowledge of any good shops here, so I'm doing it myself, any information would be appreciated greatly,

 

Er. I'm going to go out on a limb here but, the H23 manifold?

I have a question; did you read up on any resources before you tried doing the swap? I mean, it's been done successfully with plenty of guides, parts lists, etc. so I'm kinda not understanding why you're coming up short on information.

Like this link for instance.

Hahahaha

 

Thanks for the links, the information was extremely helpful, I have done extensive reading on the subject and have most of the parts I need, yet I've read tons of contradicting info on the intake manifold some say the h23a can be used most say they can't that's why I asked. But big thanks man I found tons of useful info in the links

 

If it's the JDM H23A dohc vtec engine, any H22 manifold or K20 adapter plate will work. If it's the USDM non-vtec H23A1 then you're stuck with the H23A1 manifold. The H23A1's upper plenum & IAB plate are identical to the H22 version, but the lower section has a different bolt pattern on the head.

 

Thanks it's a vtec, h23a I herd the h22 works but I think ima go aftermarket instead, might as well if I'm going to need to buy a manifold
