I am looking for a turbocharger capable of handling up to 500Whp safely and fit a T3/T4 type manifold. What turbo can you guys recommned that is reliable and priced reasonable? Thx.

 

35R, 6262, pm user shodan about the "reaper"

 

I likes Garrett 60-1

 

You dont need a 35R to make 500hp. A 30R will get you there with less lag.

 

PM the shodan and ask about the following units

Reaper, 3540S, and Silver surfer. All custom by his company.

30r, S258, 5857, 6262,

 

^^^ This. ^^^

If your budget allows it, you can't go wrong with the GT-3076R for that power level. For something a little cheaper, with a similar powerband, look into the billet Precision 5857. The BW S series turbos (preferably the S258) are a nice choice. And as Alex stated, the Reaper and Silver Surfer are prime choice Garrett units that fit the bill, also.

 

My 84mm GSR with a GT30R made 550whp. That was at 25psi with it falling to 23 at 9k

 

Garrett GT3076r. You cant go wrong. On a b series the spool is awesome. Buddy of mine just installed it on his car and made 543whp with a 30r .63 hotside.

 

I used a cast wheel precision 5857 journal bearing turbo last year and it had an awesome powerband. I made 450ish on only 16lbs.

 

You'd be pushing that 30R to make 500whp though - he didn't state whether it was stock block or sleeved block.

Either way there would be little to no room to grow after with a 30R, I stick to my original recommendation - 35R, 6262, Reaper

 

It was on a 84mm sleeved block that made the 543whp on race gas. My brother had a stock sleeve LS a couple years back with his old set up on the 3076r it made 506whp at 22psi on race gas. It can be done and not so hard.
