so if your planning on building a street car with about 600 whp on gas (just useing an example) would it be better to use higher compression pistons or lower?

A higher compression motor will make more usable power on a street car. The motor will make power lower in the RPM range and will spool a turbo faster. Your max boost level will be less on a high comp motor all other things being equal, but its power that makes a car fast, not psi.
I would rather have a motor that makes 600 hp at 10lbs over the one that makes it at 30
Yeah. But when you run high compression with a turbo you are more likley to blow up your motor...

Also, running alcohol base fuel like E85 uses less energy than the equal amount of gasoline thus you can running a higher compression block.
E85 has higher octane rating than gasoline so it can be used in higher compression engine which tend to produce more power per unit of displacement than gasoline.

Lots of people in here making that and more with 2.0 liter 4 cylinders. I suggest you try some of the Ls based forums, or yellowbullet to learn how to maximize the power from your engine.Hey
I have a 1998 Ls1 iron block Twin Turbomaking 650 RWHP.
Lots of rip offs in my drive to get it all to work.
My Engine is 9.5:1
All high grade components
**Due to trying NOS
Felpro Gaskets
Larger ARP Bolts
** Rocker arm train: tied all rockers together
I pulled a lifter
I used the STS rear mount Turbo
It took 3 shops & $6000 to get them to work properly
