How much boost can you safley push to a stock jdm h22 bottom end? anyone know? Ive got a turbo but I dont know if i want to install it with out building my bottom, depending on how much boost I can push to it. id probably have to change out my stage 2 cams back to stock because of the high compression ratio right? any input would be appriecated.

I say 10 reliably. the H22 sleeves are probably just as strong if not stronger than the F22 sleeves. its the rings you have to worry about

I thought everyone was afraid of the sleeves b/c they are aluminum and not steel they can't take that much boost. And if you mess it up you have to put sleeves in b/c you can't bore them. That's what Honda Tuning said, you can bore but it's not anything worth bragging about and there are not a whole lot of shops w/ the equipment to do it. IMO, if you're looking to make real power just sleeve the block, even if you run lower compression pistons that still doesn't mean the sleeves will be able to take the heat.
Just b/c U post more doesn't mean U know more!

Bottom line is the sleeves are thin. If you not going to run in a safe low boost zone, then no you don't need sleeve. If you want to run higher psi then you need sleeves. Big price diffrence sleeves will hurt your wallet more then just lower compression pistion. Just go w/ what your instinct and wallet tell you.
Oh and post lost a pics and dyno sheets.
Just b/c U post more doesn't mean U know more!

BOOM!

The original question was how much the STOCK h22 bottom end can handle, and in my opinion it can handle just as much as an F22 until it needs new pistons, in which case it wouldnt be a stock bottom end anymore and its a whole 'nother thread
