Would like to know some of this as well. Im trying to finish up my build and don't know if I need to go to bigger turbos or just up the boost with some meth. Im running 13 psi and put 660 to the ground.

Not in quite a while, im doing chassis work on it right now and its completely gutted. I decided against running my t56 and sold it, i placed an order for a stage5 4l80 from Jake's a couple of weeks ago. the turbos will spool damn near instantly with an auto and you still probably wont any noticeable lag with a stick.

I'm running a 378 cid 6 speed, Turbonetics 6165's, made 950 rwhp at 14 psi open down pipes. Went back with full dual 3" exhaust with mufflers and at 13 psi put down 904 rwhp but was smoking the clutch bad. I suspected the clutch was slipping this confirmed because at 16 psi the motor blew through the clutch like it hit neutral. Got the clutch up graded and haven't got it broke in yet to go back. But no doubt it will do 1000 rwhp. Oh and .68 A/R housings and E85.

is there anyone running the smaller turbine? the 62 vs the 65/6 or billet wheels? im guessing the the 62 should out spool the larger units but im worried it would choke in the top end?
i ask because i can get a pretty good deal on a pair of billet 64/62 .7ar TC
