I think a S480 at 25psi would be mid 1000 wheel. I don't see that happening on stock rods, even the larger ones..

That said, one way to find out is to push it.

 

We'll see how far it goes in a couple weeks

 

Well Right now I still don't know which way exactly to go. I have both single and twin kit. I may stay single on the truck and do an s480 then keep the twin logs for a fox body I'm in the process of buying which I already have a 4.8 in the shop for. My main concerns were the oil feed and return locations. I wouldn't want to do it wrong and ruin 2 turbos lol. Ill post up some pics soon of the hot pipes I purchased for the twins

 

I drain the twins into the exact same spot I drain the single into. Makes no difference, just costs a little more for the fittings.

 

I wonder how much stronger they are? So far iv seen the 5.3s hold 250 more hp, I know 750 rw is the limit on the 5.3s before they start to shorten, and I guess theres a few in the 950-1000rw range on the new ones and haven't poped yet.. who knows

 

Ordered a set of cx racing gt35 turbos. Should do the job to get about 800+ rwhp
