Got the differential installed. Can't wait to test drive it! I've heard the difference between a 2.93 and 3.73 is extraordinary. Cleaned as much as I could while I was in there, of course.
its funny reading this thread. i pretty much went through all of this in the past year. the 3.73 transforms the car which you've probably noticed by now. another thing that made a big improvement was replacing my FPR with a brand new unit. If your FPR mileage is unknown, it might be worth replacing.
Hah, yeah! 3.73 makes it a totally different car. To be honest, I'm not completely convinced it's really a 3.73. I'll have to measure with a digital tach -- either mine reads waaaaay high or I was sold a shorter diff than advertised. It was missing the tag when I bought it so who knows. Either way it's a real LSD and it's quiet, so I'm satisfied. It had enough lockup to let me torque down the axle bolts by just putting the car in gear. I replaced the FPR with brand new Bosch last May, so it's good. Aside from a slightly erratic idle and burning some oil, drivability is top notch.
I just tried a 4.10 lsd in place of my 3.73. It was crazy fun, 5th gear at 75 was revving very high at -/+4,000. But it kept me honest. The fun part is it pulls to 100 very aggressively. I'm going back to my 3.73 for awhile but now I realize the significance of the diff.
Thank you for posting your detailing pictures, very inspiring!! Please keep posting. Best!
