H23civichb

I'm about to pull a H23 out of a wrecked prelude with plans to swap it into my civic hatchback. The engine has 188k and with that I plan on a rebuild, but this is where it gets tricky. Not too far down the road, I plan on adding a turbo but i'm not too sure what kind of things should be replaced if I plan on turning the boost up to 15psi. I'm already looking for stronger pistons and rods, but would like to just get the stock crank turned. Any info. would help me out alot. Also, if there is anyone out there that has seen/done a H23 swap into a 5th gen civic, let me know.

Absolut

Uhmmm we do have an FI forum....

yes, 4th gen and h23 go hand and hand,

ok as far as teh engine gettin 15 psi of boost. that is a little bit of a stretch i think, cause i rarely see a prelude runnin boost that high, so a 15 psi of boost would require a full engine built up, piston and rod, and sleaves are a good idea, knift teh crank, lower compress to get that much boost, head work would be good, and dont change the cams, or get them regrind,(that all u can do to a h23 cam anyway) to ur aplication after u have finish, just the full built engine should do, 12 psi is wat i suggest, but teh FI guys should know better then me

good luck

h23 all teh way

Thanks for the info guys. I posted some stuff on the FI forum, and i decided that running 8psi would be plenty for now. i figure this should give me some good gains without having to completely build up the engine.
