Also if i sleeve the block will the head take all the pressure from the amount of boost? how do re-enforce the head? thanks for all of your help and suggestions!
I dont know if anyone makes pistons for a S2000 but crower will make whatever you want. Alls you do to lower compression is get dished pistons most hondas are domed to raise compression lower it like around 8.5: or even 8:1 and toss 25lbs at it all day !! Sleeve the block post it if you want, Billet H beam rods.. Balance the internals, Build the head with ferra valvetrain nice crower turbo cams adjustabele cam gears AEM EMS or MOTEC or some sort of managment. Just the basics, Build it for what you want. add a nice fuel system and say hello to m lil friend. You could bore it if you want but i dunno the specs on the F22 to know how far you could take it maybe like 2.4L 2.5L might be pushing it. BUt thatd be a beast !!
