Re: f22a block with f22 vtec heads

I hate to say it, but search first. I found heaps of info really quickly. Accord drivers ask this all the time.

The F22b with Vtec out of a '94 to '97 Accord is technically a Vtec motor, but it is a much tamer version than that of the H22's. The changeover is at only 2500RPM and is geared more towards fuel efficiency than kick you in the ass smile on your face happy times. This F22 is only SOHC too. They put out heaps less power than a H22 overall. The F22B out of an Si JDM prelude is DOHC but I don't think they were Vtec.

Adding Vtec to an engine is more complex than just swapping the heads over too. You could throw a H-series head on but the F series is not a high revving motor so it's not ideal for this without a fair amount of bottom end work anyway. Really, I don't think the small gains are worth all the trouble, just drop in a H-series.
