620Turbo4x4...Your information about the Z22 pistons and valves not being up to the task is completely false. We do it all the time on HybridZ...bone stock L28's making north of 450HP when turbocharged...and we're talkin' 150,000 mile junkyard engines!

 

It's all in the tune. And no, the valves won't melt unless you don't keep the valve lash set properly.
