F20B FAQ
F20B
Accord/Troneo Sir and Sir-T (CF4) (JDM)
197hp@7200/145tq@6600
85mm bore
88mm stroke
145.5mm rods (f20b rod length = 145.425)
1.65 r/s ratio
55mm mains like h22a4 block
rod journal has been offset ground on both sides to the size of a b-series rod journal.
11.0:1cr
smaller, b-series rod journals
beefy rod, like a s2000
23mm wrist pin
exhaust manifold = H22
intake manifold = h22
dizzy = h22
timing belt = unique, uses 156 teeth, you can use a h22 one. (see below)
waterpump = h22
Oil Pan = F23

Belt that came with my f20b from h-motors
14400-PCB-004 Teeth count 156
New H22 timing belt part number
1400-P13-003 Teeth count 155</TD></TR></TABLE>
Engine is a mix between the H22A4 and F23
Misconceptions about the F20B:
1. It does NOT come with a single stage intake manifold. That is found on the H22A7 European Accord type R. For everything that you'd ever want to know about that intake manifold click here:
https://honda-tech.com/zerothread?id=1960750
2. It does NOT have type S cams. It is believed that it has the same cams that are found in the JDM H22.
EDIT, 09/11/07: Manual version has type S cams, Auto Version has regular H22 Cams
3. Most engines will be from the automatics which have a smaller tb and weaker camshafts.

Specs of other honda ~2 literish engines for comparison

Re: (HeikDiesel)
So just to clear some issues up on another forum. On the F20b's does it actually have that stamped on the block (I believe they do)? Or does it still have H22 stamped (which makes no sense to me).
Gracias!

I am going to have to disagree with this comment. I have had 2 F20B motors and am currently using the F20B cams in my car. I spec'd them and also degreed them in the past. They match up IDENTICAL to the H22 Type S cams listed on the Crower site.
http://www.crower.com/cat/impo...shtml.
Normal JDM cams have the same lift, etc as normal USDM cams. I have dynoed both cams on my motor and F20B cams have much more lift and different duration and ramp angles than normal H-series cams. Here was my dyno comparison: http://www3.telus.net/public/unrynhen/camdiff.jpg
