Turbocharge a 2001 4.8 chevy shortbox
Hey there performance people!
So I have taken it upon myself to turbo charge my 2001 silverado 4.8 LS. I want to get between 500-600hp and still run off pump gas. Will also need to find a tuner to tune for the boost.
First off what size and make of turbo is going to give me a fast spool speed and still create up to 1 bar of boost?

Any decent 75-78mm turbo should get you there but you'll need a nice camshaft along with injectors/fuel pump aswell. I'll leave the brand up to you, some can be had for 400-600 from vendor's like VS racing or you can spend more on a borg or precision turbo.
Just be aware that around the 500-550hp is the limit on a skinny rod 4.8 like you have.

Do you think these flowtech forward mount turbo headers will be any good for my project?
And would 57lb/hr injectors be enough?

They'd work if you want them to work. You can buy a turbo manifold from a vendor and build your hotside if you wanted too. Or create a fully custom hotside. Using those would keep way more heat in the engine bay though.
57lb/hr would be enough for 500hp on pump gas for sure. Just make sure whatever injectors you get are decent quality.

Which vsr turbo would you recommend I'm thinking of doing a rear box mount to save money on piping plus under hood temps would be able to use my stock manifolds. Only my intake and intercooler would be in the bed.

I know this is an old thread but I have seen a couple rear mount setups not doing to bad lately. Most recently an 80 mounted in the bed of an S-10. CX racing A2W in bed also. Turbo sizing and pipe sizing being the biggest factors.
