Re: Piston Help!!!!!
Personally, if you're gonna boost, I wouldn't go over a 81.50mm bore otherwise get your block sleeved. Wall thickness doesn't really determine what pistons you should get. I'm running some Supertech 81.50mm 9.0:1 pistons. They're forged, they're the same pistons a Mahle supposedly, and they only cost $380 with pins and rings!

Re: Piston Help!!!!!
Since you're gonna sleeve it, use darton sleeves and send it to a vendor who can do the sleeving for you. They have sleeves at different sizes or you can bore the sleeves out to the size you want. The bigger the bore, the more torque! If you really wanna go big, just get the 84mm bore size and some 84mm pistons to match it and you'll be puttin a ton of torque down. dancing_ninja is right. Don't go below 9.0:1 because anything below that is gonna be compression for a track car that's gonna be making 600+whp with 30+psi of boost. I know supertech has a 9/9.1/9.5:1 pistons from

You can choose the compression and the bore size you want, and they're only $390!!!!

Re: Piston Help!!!!!
see here is the thing my machinists scratched a stock sleeve and what I think I am going to do rather than sleeving it I'm just buying a new short block and boring it 81.5 with supertech 9:1 pistons would this be better?

I would go 84mm with Arias racing pistons 9.5:1 and Eagle H beam rods.

Re: Piston Help!!!!!
If you're gonna buy a new short block, I wouldn't even bore it then. Keep the sleeves as thick as possible. I only needed to bore mine to 81.5mm because I wanted my pistons to have the perfect clearance and a hone would've made it just too wide because its been honed before. If there's no need to bore, then don't. Hone it and leave it at 81mm. Sleeving is pretty expensive, and honda sleeves in a gsr are pretty strong as long as you aren't running too much boost and you have a good tuner.

Re: Piston Help!!!!!
arias pistons are the best, with stock sleeves go 81mm, for aftermarket sleeves go for 81mm too so if you damage a sleeve you can bore it again and again and again...
bigger bore doesn't make that much difference...
