f22b..to f22a or f23

[H.R.C..CB7 jdm]

i have a f22a nd also have a f22b head i was thinkin if i was to put the f22b head on to the f22a would i have eny type of problemz?? but then i was told if i was to put the f22b head on to the f23a i would get more hp..can someone tell me witch one would be less of a pain...

[wed3k]

the dohc f22b heads are a direct swap onto a f22a since they are essentially the same bottom ends.

[cb7_orlando]

wats the up gain with the dohc head over the sohc f22? And isn't the f23 more up then both? Idk how much power the dohc pushes

[Houston93CB7SE]

Can you do a F22B head on a F22A and keep the F22a ecu? What all is involved with the swap?

[deevergote]

The F22B DOHC makes 160hp, and most people do retain the F22A ECU.

The SOHC F22B heads are garbage.

[bagoon316]

the f22b dohc is 160, but it wont make that on a f22a bottom, cuz the compression is less. it would be a better gain still though over a f22ax though.

and yes deever said it best, f22b (cd5 heads) are garbage.

[deevergote]

What's the compression on the F22B DOHC? Is that due to the pistons or the head?
People keep saying that the F22B and F22A bottom ends are the same, but does that only refer to the way the block and head mate up?

If the F22B DOHC pistons give higher compression, that could be something for the F22A guys to look into as a performance mod! Then again, if you're replacing pistons, why use old, used pistons when there are better aftermarket pieces that can be custom made to any application...

with enough money, time and patience, anything can be done.

usually cb7tuners only have time.

the specs for the F22B are listed here^^. I just had this thread going about 2 days ago with a poll on it. I have learned alot through the research I have done and came to a conclusion yesterday so, good luck with your decision.

[Houston93CB7SE]

So with a F22B head, on a F22A1 block & internals, what sort of gains would that net?

hahah so true.

even better, you get to be in with the DOHC hype!!!!

[wed3k]

technically you wouldnt gain anything more than a regular f22b. if you milled the head, did a competition valve job and delta cams, you could probably see 20hp with a tune.

mill .030 and gain half a point of compression, you'll almost be to 10.1

Too true.

So, about 20hp with just a F22B head, on a F22A1 block?
About 45hp with the whole motor swap, give or take a bit?
