which brand name piston has the highest compression for a gsr? I thought spoon was, but i might not be right.

 

if your talking about OEM than i would say PCT's (CTR)

arias pistons can make some heavy duty forged high compression pistons

 

If the ctr (PCT's) are too much then the JDM B16 P30 pistons are about 11.5:1 roughly.

 

you can get pistons made in any compression you want

True but with aftermarket pistons comes floating pins and then different rods blah blah.

 

Yeah you can't just throw in High Compression Pistons and be done with it.

But since you asked...Arias makes some REALLY good pistons.
