And to terminator below, the GT25R maxes out at 14psi, anything else is out of its efficency range and the turbo will only blow hot air. And honostly, the gt25 and gt28 should spool up almost evenly consider the gt28 is ball bearing, but is a larger trim. I can tell you a t3/t4 increases lag like crazy, i spool up at 2600 in my sr with the stock gt25, the gt28 should be around 2600 or so, the t3/t4 is over 3K, not sure how much, but its def. noticeable.

my friends 240 came with the GT25R when he bought it and he hates it. It takes way to long to spool up and is maxed out at 20 PSI. this winter he's doing a top mount with a bigger turbo, not sure which turbo he getting. he wants 450-500 to the wheels.
