67 Camaro LQ4/T56 - help me pick a turbo! So, I'm at the point in my build where I need to start looking into a turbo. I'm set on running a single for packaging reasons. The car I want to be a "jack of all trades" so to speak.
I don't want it to drive like a big turbo Supra that only has 1000rpm power window - a strong midrange is what I'm looking for. I want it to be enjoyable on the street, run well on the highway, be functional enough to road race and occasionally go down the 1/4 mile...all listed in order of importance. I plan to call Forcedinductions when I'm ready to squeeze the trigger, but wanted everyone elses opinions first.
I'm strongly considering a PT76-GTS, or to a lesser degree an ST76/ST80. The max power I want the turbo to be able to support would be 800rwhp, but would more than likely keep it in the 650-700rwhp range. I plan to use a FMIC and meth w/91 octane. Its a stock LQ4 now, but will be a forged 9.5:1 370 soon enough.
Thanks for any input!

PT76GTS - winner!
I don't think you will get 800 out of it on a 370 based on dyno posts I've seen.
The ST with the 83mm turbine should. You'd have to ask Dr Turbo or Jose about the spool.

Does anyone else have any info on the spool difference between the two? How about the weight...I'm told the ST80 weighs a ton - does anyone have any idea what the weight difference would be between the two? I realize it seems silly to compare weight, but I went to the effort of moving the battery to the back and want the car to handle somewhat, and putting 50+ lbs on the nose of the car is a step in the wrong direction handling wise.
