Re: H22 MOTOR WITH H23/F22 CRANK AND RODS (NICEHATCH)
This is just my 2 cents...take it as that...
Honda/Acura's have tight tolerances for bearings, with that said the h23 vtec it's even more crucial. I would say on the safe side would to get it balanced. You will need to bend the oil squirters. I think they are necessary for longer lasting engine. I was planing to use ARP rod bolts with the f22 crank and rods. GSR 9mm rod bolts will work on the rod I do believe. From an h22 I believe the GSR 9mm rod bolt hangs about 1/4" longer which may be/may not be a problem for clearance when you drop everything in. The pistons will stick out of the hole .020. thats .026 above stock. Since the piston from factory is .06 in the hole. I wouldn't chance reving it too much past 7500-8k rpm. I can't see agressive cams lasting too long with the engine. If you want to use agressive cams might want to use aftermarket rods and pistons maybe...which would require a proper honda hone...if you did want to use agressive cams a thicker head gasket may be a good idea...for added valve to piston clearance...for a race motor that isn't ran often/last long you can get away cheapily...
