does H22/23 header bolt to an f block? - Honda Prelude Forum

would an H22/H23 Header bolt up to an F series block?
i wonder if the bolt pattern is the same.. anyone who's done
the swaps.. whats the difference? thanks..

isnt the F series SOHC. i dont think you can just put a DOHC onto a SOHC block. i think it would be more trouble than it would be worth.

Dont think there is much interchangability between the F adn H series (The fuel rail is the only common part that I am positive about)

nope doesnt fit. The h22 and h23 header arent interchangable either.

anyone know what the differences are? bolt patterns?

But the 92-9(?) Accords LX's would. They got the same engine like us.

The exhaust might not line up right. It might, but I cant say for sure.

the reason i'm asking is because obviously their headers are designed a little more performance oriented, and yes i believe the lx headers would bolt up with no problems, as far as exhaust not lining up, do you mean accord or prelude? and wouldnt the header fit either downpipe correctly? i mean if i purchased it i'd probably just grab the top portion not the down pipe..

what do you mean?

The complete Accord header, would be slightly different from the Prelude S header. The lenth of the cars is different, so chances are, the b-pipe length is different. The primaries however, should fit fine on both cars.

well thats pretty much what i'm after, i want the primaries
since thats where the power is pretty much, maybe open up
the downpipe a little i'm hoping for a little gain at least..
