Now, if you decided that MPG is still high priority, then you could go with an LS tranny. Longer gears than the GSR to include a longer final drive. That would still be a fun Boosted LS and be able to maintain good MPG.
MPG has less to do with RPMs and more to do with Throttle Position.

anyways, I agree on the point of shorter gears being a pain sometimes on the daily drive, I'm constantly changing. You can, however, never leave 3rd gear while taking a corner at an intersection. It's just a different method of changing gears - for instance - where you would have to go down to second in an LS or GSR transmission in order to keep enough RPMs to make the corner; third works just fine in a B16. And yes, highway cruising is 80mph @ 4500... but with a decent exhaust (you have to pay to play) - it's not obnoxious at all until you punch it.
