F22 or F23 ... (boosted)
Ok, So Im planning on Finding a Low Mileage motor to replace my turbocharged Original F22...
My question is: ....
Which motor is better for boosting? The F22 or the F23 ?
I Do Not plan on touching the internals...
Thanks

The compression ratio for the f22a1, f22a2, &f22b1(VTEC) is 8.8:1.
Compression for f23a1, f23A4, and f23A5 is 9.3:1
This is according to the Specs from a link in the DIY section. I believe the data is taken from a Chilton manual so I'm not 100% sure it is totally accurate. The same table shows the f23A5 puts out 150hp and I know that is wrong (it should be 135).
Looks to me that if lower compression is what you are looking for, f22 is your winner.
It is also my understanding that turbo manifolds are pretty hard to find for the f23, whereas they are readily available for the f22.

Ok cool,...... well then, If I plan to stick to F22 so Everything fits Exact.... Do you know which F22 (VTEC or Non-VTEC) has a lower compression?
Im sure they both have the iron block?

MSN.com shows the VTEC f22is much lower compression than the non-VTEC: http://autos.msn.com/research/vip/sp...&trimid=-1
Again, I cannot vouch for the accuracy of MSN, but I think they are usually pretty good.
Crap....I just realized MSN says they are DOHC (obviously wrong) It also says the f22b2 is turbocharged [:@]
Here's Wikepedia's specs on f-series engines: http://en.wikipedia.org/wiki/Honda_F_engine
