Got some info present and to come for ya dude. I run a dom 2.5r on mine now, and see full boost on pump right at 4k, but I have a ppg helical 1-4...the turbo would be balls with the oe 5spd or a 6 spd. The coming news is tonite I bit the bullet and have my perrin 3076 .82 a/r kit shipping to me next week...I don't auto X, just a weekly drag racer. I am running 93 pump only and am looking for a solid 11 second set up which I think the rotated 3076 will do on 93. I'll post up the results soon after I get it in and on. The dom 2.5r will go up for grabs right after, has about 2500 miles on it at 20-23 psi max. For info purposes, I got a best time of 12.1@115 with the 2.5r so its not a bad turbo at all just not enough lungs for the ver 8 motor at the 1320.
