I have a JDM F20a1 in my 92 lude si (2.3l). My exhaust manifold is doing something funky, and instead of wasting time with it, I'm just going to opt out for headers, which isn't bad either. So far, parts from an H23 (such as the ps pump, alternator) have fit. I need to know what headers are going to fit my car? The F20a1 is from a 90-93 Accord si, but from what I've researched, the American to JDM specs look different. I JUST DON'T KNOW!

Anyone?

Use the H22 header. The head is essentially the same as an H22

Does anyone else have an opinion or prior knowledge? Or does everyone agree?

I'd really hate to buy headers... and find out they don't fit.

THANKS!:bigthumb:

Problem is most people aren't familiar with that engine over here and aftermarket parts are generally geared towards h22 / h23.

I bet if you find the heads are the same, then yes, use a h22. I would suggest finding a template or just finding a cheapo junkyard h22 header (stock one) and seeing if that fits. Maybe find someone about to upgrade or take theirs off and ask them to draw you a template.

^all of them are the same. The Euro-R/F20a/h22 -

All of the exhaust ports are like this:

the H23/f22 is like this

He'd probably just stand there with his guitar on and just talk about irrelevant nonsense. Kinda like he does here.

Hey Jagass, post a pic of your Civic so we can all see your handywork.
