Other than that Im not sure, maybe a higher cam lift, better air to engine, better fuel, Honda does crazy shit like that.

i have an a4, and it has a regular ol' stock header, which i doubt its any diffrent then the a1.

 

[mrm190]

yeah my a4 has a stock header but they wouldnt change the casting numbers just for the header.I figured it would be internal .

isn't the f22a4 the EX version accords?

From what I read, the 90-91 Accords came stock with a 2.0 liter engine, and the ex's came with the 2.2 liter engine. There might be a few changes from one to the other. In the 92-93 EX engines, the added a header, a different intake manifold, and a different cam. They look almost identical. 92-93 EX engine was the F22A6 = 135 hp

Just a few little changes, for just a few more horsepower, period.

Later

all 90-91 accords came with the F22A motor

Oh yeah, duh, brainfart, I was thinking of the JDM 2.0 liter engines, which have higher compression, and 20 more horsepower. My bad. Later

I have a 91 EX Coupe with an F22A1...but I have a wrecked '93 Prelude S with the F22A4. The motor from the prelude is fine...do you think it would be worth the trouble to swap?

 

[dohcvtec_accord]

Nope. It's pretty much the same damn engine.

Oh yeah, next time, start your own thread for the question.

 

[1991AccoLudeCoupe]

Sorry...it was my first post


Sweet ass ride, by the way. I hope to have my engine swapped in as cleanly as yours.

 

[dohcvtec_accord]

No worries. Next time you're banned though.



Thanks for the compliments on my ride. The swap wasn't too bad, I was amazed at how easily it went it.
