One Thing You Could Do Is Search Because There Has Been Alot Of Threads On This!!

Ok!

This engine also spawned many variants, according to market, but the specs remain largely similar

My ride, also a F20A

2.0L F20A DOHC

I too have a lot of questions, since I just joined the F20A bandwagon. The first thing I realized was that my stock F22A1 (rotting in some garage) is much quicker at accelerating than this one, although it's still fairly new to me (as my car is still at the body shop).

On a lighter side, can I stick a 2.0 Si emblem (from a Civic) to my cb, since they're the same specs anyway?

[deevergote]

No, don't put the 2.0 Si badge on... it'll blow up your motor!


Just kidding. Do whatever you want. It's a badge. At least it'll be accurate!


The F20A has less displacement, so the low-end torque isn't there like it is with the F22A. The F20A should be a better performer than the F22A in the higher RPM range.

[F20A CB7]

Ok which F20A do u have?

The F20A si (dohc) is much like the f22b/h23.

Now for the SOHC which i can relate to, cuz i have it, is very similair to the F22A motor.

U can change out yout INTAKE MANIFOLD for the H23, u will have more air flow by doin this.

U can get a cam, and jus about anything else u can put on a F22A u can put on the F20A sohc.

The Heads are the same, jus the bottom end is smaller, so u will have quicker/higher revvs

Now the F20A Si, is 10 hp and 10ft tq LEss than the JDM f22b.


I have 2.25 from cat back, 11.5 flywheel, and a stage 1 clutch and i couldnt b happier with my MOtor. TWIN cam f20a costs jus as much as a SOHC

[lokuputha]

my stock F22A1 is much quicker at accelerating than this one, (F20)

my F20A DOHC & tranny combo is much faster than my F22A1 ever was.

yeah if you have the economical SOHC thats another story.

[lonski]

So just to clear things up, SOHC is not Si, only the DOHC? I've definitely got the SOHC, do you have a link of where I can buy the intake manifold upgrade?

[F20A CB7]

my F20A DOHC & tranny combo is much faster than my F22A1 every was.

yeah if you have the economical SOHC thats another story.

Theres nothing ECO friendly about the F20A sohc motor. I waste jus as much gas as a F22.

lol.

[F20A CB7]

I would like a twin cam, but for now i would like to at least get a 272 cam, h23 mani and header, chipped ecu.

Then ill get a SI , i wanan c how good she will run with the SOHC 1st b4 i upgrade.

SOHC can be a pretty mean setup. Considering you have less parts moving, it might even be more reliable if you make it into a high rpm or a turbo setup.

of course some good head work should be considered.

[F20A CB7]

F20ACB7= PS, How can i know how much HP i have from my F20A, its from JAPAN, but is it equal to the dx, lx, or ex motors?

I thought that the F20A from Japan was smiliar to the F20A2,4 in Europe.
That means that you have 136 HP, just like the EX engine.

ACCORDIN TO LO-SPECIALS...

does this sound accurate?
