Kinda newbie question... what do you guys mean by resleeving? Is it something to buy or labor... etc?

satan_srv

both. It involves machining out the stock piston sleeves and putting in stronger iron ones.

Resleeving is needed for those of us who want to run aftermarket pistons. The blocks in our preludes have an aluminum based sleeve, designed to work in harmony with the oem pistons and rings. Aftermarket pistons will not work due to the increase in friction it can and will cause. So we resleeve.

That involves drilling out the stock sleeves and pressing in aftermarket iron sleeves. They then are sealed in the block and tested for pressure. You can then have the piston bore enlarged(bored) for more displacement. The main benefit is for the ability to use forged pistons, but the potential for more displacement doesn't hurt either.

The cost for sleeving ranges from $800-1000.

If i were to resleeve my block with darton sleeves then have it bored .25 over, what would my displacement be???

satan_srv

.25 like mm?

H23 Bore: 87mm
H23 stroke: 95mm
Stock displacement = pi*(87/2)^2*(95) = 564728 m3 = 564.728 cc x 4 = 2258 cc

Bore = 87.25mm
Stroke = 95mm

Displacement: 2271 cc

If you're gettting sleeves why wouldn't you bore out more? Forged pistons come in lots on bore sizes...up 90mm

mmm 90mm bore, 95mm stroke = 2.4L!

Like satan mentioned, you want to think mm's not inches. You mean .025 (twenty-five thousanths) and that is roughly .6 of a mm.

If you were to bore 2mm over, like I did, it would be closer to .080 (eighty-thousanths). Ask any domestic guy if he ever goes .080 over, wait to you see the expression on his face.

To check your displacement, without having to know the formula, there are a ton of calculators available.
