Check out my thread on "GT35 for 3.4L"...exactly what you are asking. I have the G50, 3.4, Motec, etc..but a relatively large turbo that doesn't kick in until 5500 in any gear (set up for track). I hate that I can't "scare" myself in 1st gear! (and need to be doing 60+ to feel the boost)

So...I am in the process right now of installing a GT35 and retuning. Hopefully, I get some boost in 1st gear and lower the boost threshold in the other gears - based on the facts (ball bearing, going from .96 A/R to .82 A/R), input, and other's experience - this should be the case.

I will know FOR SURE in a couple weeks and glady report on the results.

ps. if you get a GT35 be sure and NOT get the anti-surge option....tuner says it will increase spool up RPM by approx 300RPM, and surge is not an issue for these motors. It isn't a problem with my large turbo now.
