Making a stronger LSA for the ZL1 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

1st Gen Forever · 10-04-2011, 02:06 PM

With the suspension and driveline of the ZL1 receiving upgrades for GM to offer a warranty on an almost 600HP car, it makes a better foundation for modding than the SS if the added up front cost doesn't create too much of a gap between the two...

If one was to mod the LSA in the ZL1 with more boost, even if it took a 2300 transplant, what would need to be done to the bottom end?

Are forged pistons all that would be needed or should rod bolts, rods, etc. be upgraded? How much power and torque do you suppose it could be made to reliably handle? Has anyone researched this yet?

IMHO - you need to establish your goals and expectations first. If you're looking for 700 FWHP, you should be fine with the LSA bottom end with a good tune. You're going to see eleventybillion negative posts about hyper' pistons in a few minutes and most of those always leave out the fact there are oil-spraying nozzles for LS9/LSA to help with the heat and it's not like these are standard LS3 pistons in there. There's lower compression so detonation can be kept at bay for longer. It's already got a forged crank and PM rods.

What's you goal?

The lsa doesnt have oil squirters, only the ls9

Just to be clear (focus around the rods)

Components and design elements that contribute to the LSA’s performance include:

Balanced, lightweight reciprocating assembly
High-strength hypereutectic pistons
Sixth-generation Eaton supercharger with four-lobe rotors
Center-feed fuel system
Piston oil squirters.

I guess we can safely say there are piston cooling jets.
