i wanted to know from some of you that use this turbo what you think of it and which you would recomend for my setup i have a fully built gsr and i have the fueling for 500hp no problem, but i wanted to know if the .63 stage 3 would be the one to get or get the .82 ? thanks in advance

 

It's not bad, though for a little better spool the GT35E or SC61 would do much better. i've had both, but I've switch to TOUGE and road racing, so I went with the GT3037.

If you have a little extra cash, the GT35R (GT3040) would be the best for that GSR setup. Just finished a GSR which made over 526whp on 23psi. It was wonderful, and power-on-boost was not bad at all. PM me, I've got a spare one.

 

I have that turbo w/ .82 a/r fully built LS/Vtec and made 540whp and 400 lbs. trq. @ 25 psi.

 

i have the .63 and will be cranking to boost when my motor is broken in... hopefully it will handle 400 no problem
