Hello I'm new to this form and the ls world. I currently have a 99 ho 5.3 lm7 iron block. I was planning on putting a lsa supercharger on it but desided to go turbo instead. I haven't bought anything for the motor yet. This is going on a street car weekend cruiser but I would like to get at least 600+whp.
What kind of internals do I need to get to that mark and turbos. I plan on buying the Holley intake and larger tb. I read a lot of guys using stock internals but I don't want to go that route.

I wouldn't touch the bottom end for 600rwhp, especially on a 5.3.
