Thank you.

you ever race h22's with your f22?

the f22 is definitley the way to go, i made 176whp and 155wtq in 100+deg weather with high humidity. now i found out that was with a bad intake manifold gasket and a pinch in my downpipe on my bisi header. we are thinking 190whp on a good day with the stuff fixed. dropping the temp down to the high 70's with 8% humidity yeilded 185whp and thats with the problems still. i wish i could find my digital sheet to upload. the whole build can be done for less than 4k. here's the one in 100+deg weather.

I love my H23. It's like an f22 but you already have the big intake mani and an extra cam. Plus alittle extra compression never hurts.

[jdm92_accorn]

most of the h23's power is in the cams and the intake manifold. if you're going to change camshafts anyways then the h23 starts falling short and you can just swap the intake manifolds and sell the h23 to buy your cam and valvetrain. big plus of the f22 is the non-frm sleeves, so pistons are easier to get. your build can be done cheap. it just depends on what you want. if you want a reliable dd pm me and i'll hook you up.

I did race one from about 50mph and had about 4 cars on him at about 120mph. I got barely walked by jose's H23VTEC.

well, i was going to use h23 pistons, rods and crank in a bored f22 block, with a f22 head, (P&P, plained, bisi or delta cam) h23 IM+TB. If i did that then all i would have to do is get my block bored, head plained and buy my cam, because i already have everything else.

let me know what you do with a custom headgasket because i was going to have one made until Cometic lost my package so i have to send them another headgasket so they can make it.

mine was going to be 87mm bore, roughly .080 thick. the piston is going to stick up out of the block because of the compression height.

i thought the pistons were the same as f22 pistons, just bigger bore.

[wed3k]

i thought they were closer to h22? but you may be right since they have the same length rod while h22's have a longer rod. only thing is less compression...im running a stock domed h22. so my compression should be up there, lol.

[corkum]

Yeah, hopefully they're the same hight. I'll let you know when i get the pistons in.
