Who makes an off the shelf piston thats around 9:1? I've looked and JE, Arias, CP, Wiseco, etc don't show one. Crower has steel billet rods for around $700 and Pauter has some. What about head and main studs? ARP doesn't show anything, but could just be lagging on updating their catalog.

 

whats your plan?

most s2k ppl lower compression by changing the head gasket, but thats the cheap way...

 

Sleeved, pistons, rods, 15+ psi, GT35R

The cylinder wall is damaged and I'm willing to be that its deeper than .005" so oversized stock pistons are out of the question.

why not upgrade to a stroker kit...TODA...INLINE...then lower the compession and turbo that? no one has really done that yet, everyone is going the turbo route now, thats why im staying n/a...

anyway, ill try to find some pistons later...im sure a set for a different application might work...ex: integra low compression pistons might work or something else...

 

Only thing you could try is H22 or F22 as they don't make B-series pistons that big. The valve angles of the F20C and H22 or F22 are probably different so those probably won't work either. There are people with JE, Ross, CP, and others in their S2000's, but they are custom pistons. We're trying to avoid the price and wait time on customs.

Stock open deck sleeves, pistons, and rods can only handle so much boost.

 

They are 87mm pistons, regardless if its f20 or f22. I've heard of B series running 89mm pistons on an overbore, so it can't be that hard to find.

 

H22 is 87 also. I'd LOVE for you to find an 89mm B-series pistons let alone an off the shelf one.

I'm talking, call up, order the piston, have it the next week...aka off the shelf
