Exhaust ; B Series Header fit A20 ?

[Fuzy Navel]

Will a B-Series Exhuast Header fit on a a20? just a quick question

[A20A1]

nope, not even a JDM B20A will fit.
Exhaust port spacing is even and the ports are different shapes.

You can come close with a F23A1 / F22B1/B2 (97 Accord SE), the port spacing are a closer match... but you'd still need to rework the exhaust port shape because those will be different. Also the angle on the downpipe, assuming the downpipe is in the right spot and will pass thru the gap in the oil pan.

I dunno if the outer ports are in close enough, and the middle ports will already have a bit more of a gap considering their shape.

no, the a20 exhaust ports look like this (O OO O) as opposed to a b-series where they're like this (O O O O).

Damn, $25

are you interested in using aftermarket performance headers on your a20?

Why don't you just buy a header for the a20, and if you want to make one heres the flange.......CLICK ME!

Well the reason i wanted to know is to see if i could use a B-series turbo header on a A20 but that idea went down the hole i guess if it was that easy everybody would have a turbo... but anyways I found a couple sites with flanges and i wanna make me a turbo header, Its just i raced a Del Sol yesterday and i was fast off the line but when i got into 3rd gear he finally started to pull on me just alittle but then we had to start slowing down because of traffic so we didnt get up to around 50 and that was about it but i just could hear his blow off valve and it just made me wanna have one so bad lol....

You should have said you wanted a turbo manifold in the first place.


There are places that have already made turbo manifolds for the A20.

has anyone ever try to put an f22b header or maybe even a turbo manifold

If the ports are close enough maybe you can cut them off and rotate them 90*

I would check the measurements of the gasket but I don't feel like buying a part I don't need.

The ports aren't the only worry though, you still need to angle the downpipe and make sure it doesn't hit the oil pan or front cross member.

Whats nice is they sell stainless headers I think. Greddy and Megan Racing and such.

Are those in stainless or mild steel?
