f22 block with f20 head?
hi i'm a brand new member at s2ki, i dont have an s2k but im intrested in purchasing one, i own an h23vtec prelude and i have the following q's about the s2k.
i did a lil research on this but didnt have any luck trying to find out if any one has f20 head on an f22 block? i dont know much about s2k motors and im not sure if there is even a difference in the ap1 and ap2 heads. i was interested in building a motor like this cuz i think that would be a good setup for all motor, cuz i dont see that there is that much benefit in allmotor aftermarket parts for the s2k.
this is the setup i think should get a good hp/tq #
f20 stock head
f22 block (balanced/blueprinted/knife edged crank, not sure what pistons to use ithink jdm f20c pistons for a lil higher compression)
stock i/h/e
some sort of fuel manegment not sure which one yet
what do you guys think?
sorry if there is any stupid q's or comments im a newbie to s2ks

FI......A local I bought the head from had a similar setup as me. The only real difference he was running an AP2/AP2 setup. We made around the same rwhp, but I made it running 4psi boost less then he was. My mechanic attributes that to the block/head combo.
For your case since you're both running AP2 cams you'd gain ~10% from redline benefit but the 2.2L would gain ~10% from greater displacement, which would be a roughly a wash. The block head combo had little impact here. The reason your system is more efficient is in the turbo design/tune.
