Is there any higher compression pistons for the le5 ecotec? Would be nice to do a 11/11.5-1 or even 12-1 N/A set up on a 2.4 le5 to keep it street friendly and have fun with a 200hp+ N/A 4 banger. Anyone ever seen high compression le5 pistons? How much do you think it would be for oversized 11.5-1 pistons?

 

i know you can get camshafts and neutral balance shafts not sure about larger pistons though. contact zzp as they make alot of custom parts for the cobalt.

 

I don't recall seeing anyone that provides pistons like that. I've seen 10.5 and lower from zzp and others. Perhaps contact zzp and see what they can do? Otherwise call a manufacturer like Wiseco or something. Hat goes off to you if you do it.
