i just talked to Rev Hard and they are coming out with a GTBB STAGE 2 turbo! i have the stage 1 from them and like it alot, im running 7psi right now, about to go 10psi, and bought another a3 block and a2 head and sending them away to be built so i can run 20psi+, but this stage 2 would be a hell of an addition. they said we should see 30-40 HP extra on top of the stage 1, which is at 75hp.....do the math and thats a good number around 115hp capabilities! i believe this GTBB stands for garrett turbo ball bearing, but thats just a guess...i Rev Hard makes everything themselves.....so anyone know what the GT may stand for? maybe GT like what every other GT stands for (i.e. mustang gt)? anyone else building their SI for speed? or just looks? i have done nothing to the outside of the car....my inside is custom....but no body kit or C/F hood....
