First thread ever. Ive probably read a million but I'm in the homework stage of a 4.8 turbo build on my 2005 silverado.
I am looking to get 500 horsepower, which shouldn't be too hard judging by the numbers that people like foose04 and other guys are making with 4.8s! i want in..

I already have pac1218 valve springs, and DeatschWerks 60lb injectors. I need help for a turbo, a cam and hell anything else, im all ears (or eyes).

I was a red c*nt hair away from pulling the trigger on the MPT70 turbo, but theres so many options for a/r I bitched out. I know theres guys on here with fast 4.8s. help?

I like a S475 with a 83 turbine and a 87 to 92 for max power.

87-92 a/r? and what kind of exhaust set up?

Mm turbine size with 1.0 to 1.25ar. Exhaust size for 500hp 3.0 is good. 3.5 for max power if you want to turn it up. I think some have push the 3.0 over 500rwhp. I always think about having move to make more later down the road.

from the website it looks like they only deal with turbos as a kit. I forgot to mention that i have all of the ceramic coated piping for a mid mount set up on a t4 flange. I just need the turbo itself and everything to lubricate it. and thats a huge turbo!

Rick can get you any part of a turbo kit. Call him and please say Mark Byrd send you to him. He is a great guy.

Oh can with a mid mount I'm not sure what turbine would work best but he will.

S475/83 is way too much turbo on a 4.8 for his goals. For what he wants, an S366 would be my choice - optimum combination of power potential and spool.
