F20B V-tech

[Alex13mod]

Motor is getting put on now with a Stage 3 clutch , I cant wait to break in the clutch then rip it . The vtec solenoid is freaking huge for a single cam.

Wow... I do believe that is an F series that I've never seen before! It's not the SiR motor that you think it is. That thing is pretty much a 2.0L version of our F23A... a standard Accord motor. It'll have less torque than a USDM F23, and probably makes the same 150hp. Certainly not a bad motor, but it's not a performance motor by any means. If you bought it under the impression that you were getting the SiR motor, you'll be rather disappointed. If you were led to believe that you were purchasing the SiR motor, then you have a lawsuit on your hands!

Good luck with it. I hope to see it in person some day! I'm in South Jersey myself, but I work up near Perth Amboy on occasion.

You can't forget about the 4WD civic

Integra and Torneo too

Too bad Hondas 4WD system for these cars isn't a performance 4WD system like the Subiez....

Thats one of the main reasons you never see companies like Spoon or Trust etc. drop the conservative F20 Sohc or even the weaker F18 engine for a H22 etc and mate it to the 4WD system. It will never perform like a WRX in a drifting event Honda built it's 4WD system mainly for safety rather than performance.

yerp, honda's 4WD system aint that capable, actually, its essentially a dual pump system, not a full-on torsen type..

some peeps have dropped in the B18c into an RTSi civic, but the 4WD diff cant cope.. but im planning on dropping an H22 into my mums 4WD ody..

the F20B was offered in the CF9 Accord here in Malaysia, the F23 offered in the same gen CG2, i think.. and also the RA6 ody (2nd gen)

You have pictures of your swap? or anything?

[Alex13mod]

Ill have picture by this week hopefully, my mechanic keeps changing dates when hes mounting the motor. I talked to the boss and he Guarantee's this Thursday. If not im taking it to another mechanic.

I'm not sure how to go about saying this, but I believe you've been misinformed about your new motor. The F20B SOHC does have the 85 bore and 88 stroke BUT it has a 9.5:1 CR, not 11.0:1. It makes 150HP/6100 and 137TQ/5000. You can read more about it here (second post):

I think someone gave you some wrong figures It's not a bad motor at all, you're going to have alotta fun w/ the 88mm stroke

[Alex13mod]

ok good new motor is installed and running ill have pic tommorow. ANother thing te driver side motor mount is using a stock motor mount of my F22 um what custom mount do i need for it?

oh yeah that 150 hp is the non v-tech look
1997cc
F20A DOHC non-VTEC--obd I/F20B SOHC non-VTEC--obd II
150hp/6100rpm
137tq/5000rpm
6400rpm redline
9.5:1 compression ratio
85.0mm bore x 88.0mm stroke
closed deck and no LSD

[F22NVtec]

11:1 is pretty high for a single cam. I didnt kno they hav a Sohc Vtec f20. I thought it was Sohc n-vtec F20a then Doch F20B

[bruno8747]

There were SOHC F20a And DOHC F20a. The f20b is the destroked version of the H22A.

[Alex13mod]

Anyone know what mount i need? from driver side since im using the stock mount but is not the rite one.

[F22NVtec]

Thats koo, i didn't kno that. I have a question about electrical if anyone has some knowledge in that area. The high beams don't work and i don' kno if its the wiring or what Both lights are good an its not a fuse.

[deevergote]

The mount is correct. You shouldn't need any custom mounts for that motor.

Also, from what I could find, the VTEC motor is the 150hp motor. That is NOT the SiR motor (which was DOHC)

Motor is on and now im having idling trouble im thinking the manifold is not compatible or throttle body.

Also my O2 sensor is not plugged on could the be the idling problem?
