ok heres the deal, i will be sleeving my h23 block for turbo, however right now i need to get it running asap, so is it alright to go ahead and get my pistons and rods and install them, then later on once i have the motor running i can sleeve it?i just wanna make sure that nothing will need to be altered or that i wont have an problems, because i dont have the money right now to do it all at once unfortunatly and i'm in a hurry to have a running car...

 

You can't run a forged piston against the stock cylinder walls.You could run stock pistons only without sleeving!

Pistons have a tendency to break after being pushed out of the block. Just wait till you have money to do the whole shabang

 

Why cant you run forged pistons in stock cylinder walls? What if they are the same bore? :\

 

because you will tear the hell out of the cylinder walls and most likely seize your engine. the cylinder walls are made of FRM which is aluminum rather than iron.

 

H22 & H23 use special material in the stock cylinder wall that only work with stock cast pistons.You must sleeve the block to use aftermarket pistons.

ok thanks guys, thats what i thought but was hoping i was wrong lol.....i'll just wait and do sleeves/pistons/rods all at once then my bottom end should be set right?

 

How much are you expecting to boost and what compression are you going to run? Take this info:

Compression <Boost
10.5:1 <8psi
10:1 <10psi
9.5:1 <12psi
9:1 <14psi or more

Good luck with everything...

Not to hijack, but what about d-series engines? I've just never heard of this. I knew about sleeving and honing, but never knew it was for this specific reason.

 

d series don't have the frm on the liners

 

Neat, so I can hone and go! Thanks! /return to original topic

 

i'm getting 9:1 pistons,je or cp

i want to run atleast 15 +
