f20a swap

[Murph2381]

i have a 92 accord ex and it has over 200000 miles and the tranny is out. thinking about buying a f20a from jdmengineworld? any help would be awesome! i plan on doing the swap my self cause I've got around 30000 invested in the car! i used to show it a lot and i won first place at nopi in my class in 2001. so i don't want to take it to just any shop.

So...you invested over $30,000 in your CB7?

F20A is a downgrade really, it has a little bit more HP but less torque than a F22A6. If your going to swap get at least a F22B DOHC, H23A DOHC, or H22A.

H22A is your best bet.

Side note: Do you have any pictures of your "$30,000 CB7"?
I'm just curious.

Its not really a downgrade. Its about on par.

[CB7Nub]

Less displacement, I'd say that's a downgrade. It's about par now power wise.
Oh yes, I'm assuming the OP is referring to the F20A DOHC, not a SOHC F20A.
F20A SOHC is definitely a waste, F20A DOHC is about par now.

But here is the problem.
Good luck buying parts for it, anywhere.
Less displacement.

For the price of the swap there are better options.

[Tippey764]

Good luck buying parts? There wouldn't be any problem getting it parts

The head is identical to the h23a for the most part ( cylinder bore holes are different so the head matches it but the rest is the same )

Timing belt is easily had if you are smart about it. You could also just convert it to use an h23a timing belt.

Displacement is everything anyways.

Plus the motor stays true to the accord platform.

That statement isn't even good enough to wipe my ass with. So you're saying a 2.4L F1 V8 is insuperior to a 7.0L LS7 V8? The F1 engine makes 950-980hp and revs to 18,000 rpm. The LS7 ONLY makes 505hp. But crap, it's almost three times the size!

I only get so passionate about countering the comment because this thread was already proven worthless when the OP said he spent $30,000 on a car that doesn't even have a swap. Not saying it can't be done. Only that he didn't.

[deevergote]

.2L hardly matters. Honda guys talk about fractions of a liter like it means the world when it comes to torque. The F20A SOHC is just fine. The F20A DOHC is an upgrade, and was in one of the top CB models in Japan.

Hell, a 1.5L engine would move these cars well enough. They actually came with a 1.8L in other markets.



Also, what is this current fascination with jdmengineworld? They're crap. www.hmotorsonline.com is the only place I'd ever trust for a swap.

[F20A CB7]

The f20a sohc is not a waste , tell that to f20accordturbo lol.. a down grade. Not by much. Actually when I installed the f20a sohc and drove it felt like a 2.2 didn't really see a difference... the tru thing I did notice was I can take it to a higher rpm.


2 weeks later I found the dohc f20a and I was .. for 50 beans more u can have a dohc.




did y'all ever see the accord f20a si vs 1.8 teggy in a tunnel in ny I think?

[Murph2381]

thanks for the info

im new to all this stuff and was trying to get a plan for the swap. thanks for the input on jdmengineworld! ive been told to only go with hmotors but they didnt have the f20a dohc the have the f22a i think. also how do you post pics on here so i can show my car?

I never said displacement is the all in one winner.
We all know that ANY engine can be built to make power for your needs.
The issue is that some engine builds are:

1) Easier to get parts for
2) Have more aftermarket support
3) Cheaper

For example.
The H22A has way more aftermarket support and makes way more power out of the box. For a little bit more you would be much better off. Plus the H22A was sold in some cars here. So if you got a USDM H22A you don't have to go mix and matching parts and "testing" or "researching" to see if they fit or not.

F20A DOHC - $1100

H22A DOHC - $1400 (I know this is OBD2, they didn't have any OBD1, OBD1 is cheaper and is what we would swap in our cars)
http://www.jdm-online.com/jdm-engine...-motor-97.html

Even if you spent $500 on the F20 DOHC is would make less power than an H22A DOHC.

Now over to the displacement issue.
Do you realize the cost of a F1 engine versus a LS7 in your example Jarrett?
Of course the F1 engine makes more power, it's designed for one thing: racing. Not to mention the cost everything versus the two setups.

There is a reason why most people swap over a H22A and not a F20A DOHC.
You would be unique though...

.2 isn't that much of a difference anyways.
Your choice OP lol.

Note: OP if your going to buy a motor don't buy from the link. Go to H Motors, I have heard nothing bad from them.
They are a little bit more, but the engines are quality.

EDIT: OP easiest way to upload pictures is:
1) Go to imageshack.us
2) Upload your pictures and resize to a reasonable amount so the whole screen isn't one picture
3) Post the image ([IMG]) code here.
4) Hurrah.

[Murph2381]

[Dani Filth]

Yes.

I always wondered what size they were. Never bothered to look it up though!
