Re: Whats wrong with f-series?
7k would be fine with me, thats all I rev my b18b to anyway so no difference there. And as far as bearings, if the mileage called for it a mild rebuild wouldn't be a big deal anyway, and would give the opportunity to throw in some arp rod bolts and headstuds. Ok another question-- would using the h 50mm crank destroke the f series, hence giving it higher compression and less displacement? I dunno if I would do that, especially if people are getting good results with the stock f crank. And the h22 head would prolly be an availability/cost decision -- if i found a good deal i'd go for it

Re: Whats wrong with f-series?
the f22 mains are also 50mm. if you were to use f22 rods, you compression would drop to 8.5:1.
but if you used stock h22 rods, then you would run into valve to pistons clearance problems.
what would be the reason to swap that crank in? to simply rev higher? you would have to install some oil squirters, and ive heard its kinda hard to do that on f22's.

yes, the ports alone are better flowing than that of the h, you shoulda stated that when you said that. overall, it doesnt, not stock anyways.

but i dont think he's gona go through all that trouble just so he can rev higher. especially since he's trying to go hmt style.
and i dont know who chad is.
