Turbo guys I need your help...

I have a chance to buy a gt45 turbo from a friend for 300bucks. What I need to know is, will the turbo support 650-800 horsepower? And, will it support it to 6500. It will be going on a forged 346 or a forged stock crank ls2. Or is it too big?

so a 45 is 75-100 hp more-

it also depends on the a.r also-

pm drturbo has those guys sell them for a living-

from joining the website i have seen a lot of people talk about the gt42 or gt45-stating that they are knowed to cause back pressure problems-

maybe search that kind of thread- but i dont know which turbo cause the back pressure debate but was 1 of them-

hope that helps-
