Default 91 w/ 3.909 Torsen

1) How would this setup feel w/ ~190-200whp on a 1.6 w/ an SR20 T25?

2) Would a 4.1 be preferred for occasional track duty and mainly DD?

3) Should I just go w/ a 6speed while changing out the diff? Or stick w/ my stock 5 speed that grinds in 2nd?

Thanks.

1. I don't think that will be a problem at all. My 4.10's felt really short even below that power level.

2. I don't think 3.90's will hurt you that much on the track, and they'll definitely be nice on the highway.

3. If you've got the money laying around doing both would be awesome. If not, aside from 4 driveshaft bolts, swapping the tranny and swapping the diff don't really interfere with each other. I think I'd just do the 3.90's then plan to do the 6 speed later.
