F20a Sohc

[B00STd_FoeDoe]

I drive a 93' Accord. I've read that the f20a shares the same block as the f22a6. So when purchasing performance parts do I purchase parts for the a6..?! Also, has anybody built an f20a n/a and has a decent amount of power made an would like to share their build with a new kid on the block..

so do you have the f20a in your car now? if so, buy parts for your engine specifically. a lot of the parts may transfer over, but its better just to buy specifically for what you have.

if your looking for power, stick with the f22a6. it, along with many other, are far superior to the f20a

I bout the car with an f20a in it already.. But so far I haven't seen many parts for f20a's. Or maybe I haven't been looking in the right places..

The F20 sohc share's the same head as the F22ax. So if your thinking about cams, headers etc. Then your good to go.

^^ i have to thank Mr. Deevergote on that one

The block is not the same. The F20A block has an 87mm bore and 88mm stroke, whereas the F22A has an 85mm bore and 95mm stroke.

[B00STd_FoeDoe]

noobish question.. but i see f22ax a lot but what does the "x" mean.. All f22# motors..?

[deevergote]

That's exactly what it means.

deev, I just measured my pistons on my F20A and they are 85mm. The blocks are identical as well.

Then you should probably head over to wikipedia and edit the information there... because that's where I got it!

I'm usually good about double-checking information I don't already know for sure before I post it... this time, I trusted one source. Not smart on my part!

Surprising enough, you got the bore right on in another F20 thread.

[deevergote]

I probably did proper research before posting that time!
It's all just numbers to me. I don't have any hands-on experience with that stuff yet. Soon, I hope... whenever I get around to ordering pistons for my project H22, I'll need to know what I'm doing!

F20A has DOHC and SOHC variants, the DOHC is bore 85mm stroke 88mm and the SOHC is bore 87mm stroke 88mm

[B00STd_FoeDoe]

So what makes the DOHC better..The fact it has two cams, which makes it possible for better tuning..

The only F series motor in front drive configuration that doesn't have an 85mm bore are the F23s. (S2000 are not even the same block.)

87mm was for the H series motors.

[deevergote]

Was the F20B a true "F series" or was that closer to an H series?
Dammit... now I feel like a noob! Gotta learn somewhere, I guess!
