the boring but meticulous 2.7i

[modernist]

Can't wait to install this 3.73 LSD! Just got the cover back from the sandblaster, got fresh hardware.

Any pro tips?

Got the old diff out. The bolts were totally fused in with rust. If anyone wants it, it's ugly but quiet. 2.93 open. $100 plus shipping

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.

Great work!

Yes - the 3.73 will transform the car!

Nice work, want to come switch out my diff too?

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.

Also, a sign of things to come ... :D

Yay, standalone ecu.

Wasted spark? Are you going turbo?

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!

I'm about to swap mine after the winter and was lucky enough to find a medium case 4.10 lsd =)

Going to use new hardware too just like you and the dealer. This car is dope I can't wait to see what's next

Going to use new hardware too

Nothing like shiny new hardware. One of my favorite things (if that's not obvious yet)

Just submitted this to a laser cutter ... just for cheap clear acrylic prototypes.
