i am thrown between so many different turbos. which turbo should i get. i am looking to get 500 hp to the wheels max and about 350 when i am on the street. the 500 will be with race gas and a crazy map and the 350 at the wheels will be with american 91 ocatane. so many people are running such big turbos, but i am wondering what they rpm the lag to. also when do they reach full boost. i want to reach a full 26 psi at 5000-5500 rpm and 18 psi at about 4000-4500 rpm. please help. currently i have a turbo sitting at my house but its way to small to do the job. its a t3/t4 50 trim. if you dont know my mods, check my other post:

The bigger the turbo (cfm) the more lag, the less driveablity.
The s/r30 is as good as any IHI out there.
The s/r40 is my favorite combo for street and road racing on a track.
The s/r50 has produced 400 hp at the wheels with 12lbs of boost.
These are all instock ready to ship today.

those turbos are way to small. they are rated at flywheel hp. their biggest turbo would support maybe 380-400 at the wheels if their lucky.

 

You're looking for a drag set up?
Something that will come on boost at 5,000 rpm until 7,000 redline. Not my cup of tea. What ever floats ur boat.
