Elijah- thanks for joining the forum and for the compliments on the write up. Maybe this will help you or someone else down the line.
As far as the car goes, the trans I bought has had a crotchety 2nd gear synchro sine I installed it almost a year ago. As of a few weeks ago, I started to lose 5th gear and now it's totally gone. I picked up a 98/99 SE-R non-LSD from another forum member last week that I will be putting in today (hopefully). I won't be painting it to match as I plan on putting an LSD trans in there eventually. Says the Nissan gear bible, the G20 trans has longer legs in 3rd, 4th, and 5th so I can expect to lose a little milage but gain a little fun!
