F20B question...

[Fzzy285]

ive been looking into these more and more as i realize an h22 is a lil pricey for me.

if i swap one in with the stock 5spd tranny that i have now, will that cause any major drawbacks or anything?

are they relatively easy to find? and what do i need to look for when i do find one?

opinions on the swap?

[jhondayaaj]

actually, I believe the f20b is a lil more expensive. with your f22 tranny and h22 motor, it will still be strong. But the power band will be very different with the f22 tranny compared to h22 or h23 trans. because the f22 trans will be a lot longer than the h series tranny.

[Fzzy285]

lookin off hmotorsonline.com, just the engine is $1000, and i can hopefully find one somewhere around here in a junkyard or something. there are no preludes anywhere in this town.

[jhondayaaj]

engine for what?? h22, f20b, which one was for 1000?? and good luck on finding an h22 at the junkyards. especially an f20b.

[Fzzy285]

the f20 was $1000, i know there isnt a huge difference in price, but i like the fact that f20's arent as common of a swap

[jhondayaaj]

true that. but as for the f20b being a high revving motor, I would suggest getting an h series tranny to feel it's full potential. don't forget to mention that 1000 is only for the long block, what bout the ecu??

[Fzzy285]

ecu and everything included, as for the tranny, im looking into some different options on that, nothing i plan on doing anytime soon. i wanna do things to my cb that have never been done, or at least not very often

The F20B is a Great motor from what i've read on here. ALMOST JDM has the F20B and he loves it. Its a Destroked H22 motor. which means it can revv higher/faster.

Its cheaper than an H22. and you could use your F22 tranny for now. The matching tranny for the F20B is short geared.

[Chev@Li3r]

if ur gonna go F20B, id definitely change out the tranny to get the full potential of the motor, the gearing of ur stock tranny might not do so, unless ofcourse you're going turbo, then the longer gears are great! lol

what ecu is the f20b on?

[deevergote]

The P13 would probably run the F20B, and chipped P28 would work well... but the proper ECU (not sure what it is) would be best.

The F20B is OBD2, so that's additional wiring you'd have to do.
The F20B has a narrow powerband compared to the H22. It's not bad, but the H22 has more usable power.
The F20B DOES rev to the moon, which would be pretty fun

If you get JUST the motor, you have to worry about the ECU issue. Also, the F22A transmission has very tall gearing for the F20B. In your normal driving RPM, you'll feel like you have less power than with the F22A. It'll take forever to get to where you make power. The H22 transmission would be much better in that case.

The F20B also comes in 2 versions... 200hp manual, and 180hp automatic. I believe the weaker one is more common... and there's no easy way to tell, especially before you actually GET the motor! hmotorsonline SHOULD be honest, and they're probably one of the only ones... but even then, I would avoid it.

The H22 is consistently $100-$200 cheaper than the F20B. Compare similar packages and you'll see that.

o deev i guess you missed the memo. I bought a prelude. building it up for backroads! buying f20b tomorrow! proper ecu is pcb! thanks again bud!

[Fzzy285]

yeah, i noticed today there are a few places you can get h22's fairly cheap.

and as far as the two versions, im gonna damn sure i get the 200hp manual, i already read about those a lil bit.

let me explain what i want in my car, i am a huge rally enthusiast, so i naturally want a rallyish car. now i know everyone is gonna say for me to get 4wd, but due to past experiences with a friend rallying his old accord, i think this car has alot of potential.

so i was thinking build an f20 a bit, put on a medium, nothin major turbo, dont know exactly what i want as far as tranny, i wanna get more details on the actual ratios and what not of the different trannys. that to me sounded like a great idea

[deevergote]

The F20B has very high compression... turbo will be tricky.



Jan, do you still have the Z, the xterra, and the old blue CB7?




I would love to play with an F20B, but there's really not much benefit to it over the H22. It costs more, it's OBD2, there's a chance of getting the weaker one (I wouldn't know how to tell by looking at it), it has a peaky powerband, and any part that isn't an H22 part would be hard to replace.

The motor was designed by Honda so they could compete with the Accord in a 2.0L class. They would've used the H22 if they weren't limited to 2.0L. Everyone says "Oh, the F20B was MADE for racing!" Bull... it was made to race within limitations. That's like saying the gold-medal basketball team in the special olympics could play for the NBA!

The H22 was originally intended for the NSX
