f20b

[ntcb7]

Iam wanting to know how hard is it to convert the motor from 0bd2 to make it a obd1. or would it just be better to do a h22 motor.

Search? Its been covered about 500000000 times. I think its even in the swaps sticky.

i have an f20B vtec and had to be converted to OBD1 and had to change some sensor to take out that eractic idle noise.

That's right, you have the single cam though, right? I have to see that thing!

The H22 is still better all around. The F20B is a neat motor, but more work and a peakier powerband. The only reason to get it is it you specifically WANT and F20B. I'd love to own one myself, just for the revviness of it... but the H22 makes more power over a wider range.

is there any places that makes piston rings for this motor?? or anything similar that will work??

[almostJDM]

i havent found one yet but i know it has the same bore as the f22aX enigne's

[jhondayaaj]

I just got back from the junkyard a few day ago, and I got some piston rings from a f22a1 engine. when I rip apart my f20b, I'll compare it and will def. let you guys know.

sweet i know theyll be the right size around but the thickness may be different tho i hope not

This is off topic, and has prob been covered before, but is the F20B block Steel sleeved like a F22/H23, or does it have FRM cyl walls like the H22?

since its just a de-stroked version of the H22, i would assume it has the FRM clinder walls. i don't know for sure though.

[almostJDM]

no it doesnt have frm sleeves i belive its like the f22/h23

It seems to me that the F20B would be a better setup for turbo though deev. I assume it has F-series cylinder walls rather then the weaker H-series.

Its OBD2 I'm sure thats why its not a more popular swap (besides the modification necessary and cost).

Good point, only other thing is...would the .2 displacement but worth getting the H22 for boost over the f20b with the stronger walls
