Was wondering what sleaves i should buy for my 92 h23 si engine? Can i just use my new pistons that are in the engine or do i have to buy new ones? Going to buy new rods.. Anything else would i need for the bottom end?
Since your gonna rip apart the engine anyways u might as well drop in some forged pistons. But when using forged pistons on a h-series motor u have to resleeve it, u can't just use a block gaurd. As for sleeves, any sleeves are good. They can all pretty much hold more boost than your ever gonna throw at um. Most sleeves can handle 40-55 lbs. You can use AEBS, Golden eagle, Darton, there more but i can't think of them now.
Well the h23 is a closed deck block. also if i were you i'd go with darton sleeves. they don't sell the kits for them but they sell the individual sleeves for 46 buck. So that's about 185 for all 4 sleeves, then just take it to your local machine shop and have them install them. it shouldn't cost that much. I was quoted about 380 to sleeve my h23 and put in pistons and rods.
