Okay, here's what I'm thinking. My girlfriend's '91 G20 has 5th gear pop-out. I would like to use my '91 SE-R tranny in her G, then fix the pop-out and put the G20 tranny in my '91 NX2K. Any difficulties in the swaps, or is it relatively straightforward? Also, anyone have driving impressions on the 2750lb/.30 cd G20 with the 4.176 drive ratio...or impressions on the 2460lb/.32 cd NX2K with the 4.058 ratio? Thanks!
