i got a fully built b18 and runnin around 15lbs of boost. i got a precisioin sc61 turbo and it puts out great power it just takes to long to spool and hit full boost. im lookin to stay at around 475-525hp and still maintain a spool range of around 3500-4000rpm. any suggestions would be appreciated

 

You're not going to find a turbo that spools before 4k and still makes over 500whp. The closest you'll come is 4400-4700rpm. If you ran something like the STC Silver Surfer, Borg Warner S256/S258, or a GT30r, you could see a good improvement in spool and still make the power you want.

 

alright thanks. what about the gt35r. would you have an idea of where it would spool around and how much power it would make on my setup.

With the GT35R, you're in about in the same boat as your SC61, with a little improvement. The larger turbochargers are not going to help you with the response you're looking for wether it is a ball-bearing cartridge or not. Your displacement just won't move anything that big that fast...
