do anyone know if the h22 on 4th gen and 5th gen are the same?? i kno the length of the downpipe are different, but does all the bolt holes match????

 

good question

the blocks are basically the same but the closed / open deck issue

i dont see why not??

 

Nope. I am sure you could make it work. For the most part I beleive they are different. Where the cat mounts and where the down pipe mounts to the rear bottom side of the block, that mounting plate is a bit longer on the 5th gen than on the 4th gen.
I ran into these questions myself when my swap was done. What it that you are doing?
Are you putting a H22a4 into a 4th gen? If it has everything Header & Downpipe, I would think all you have to worry about is if it lines up @ the cat> I don't think they do.??????> I could be wrong.

 

the header bolts to the head the same for all h22a engines.

 

yes, but Cat locations and ill the hangers still line up....Im looking at getting the GReddy 4-2-1 and it says i is only for the 92-96 Vtec, I know same engine and same type chassis (BB), but my question...actually 2 is will everything line up with no modification, and didnt GReddy make a 4-1 stainless header?

The original poster acknowledged the difference in lengths...

4th gen header is about 6 inches longer than a 5th gen base, maybe 2 inches longer than an SH header. Greddy only makes a 4-2-1
