The day has came and went; we finally installed the 3.46 differential i purchased 3 weeks ago. Got it from Reno Auto, a salvage yard. The 3.46 was from a 323i with 14,000 miles on it (less than my car). Sold for $325
The total time was 4 hours to install. We had two problems through the process; 1) my car was too low to get onto the lift lol (not a big problem tho) and 2) we raped the bolts that went from the rear L/R axles to the differential flanges. I had to go out and get new ones at the dealer which were $3.68 each! x 12 of them. Luckly Tischer BMW in Silver Spring Maryland are awesome guys and got me 20% off without hesitation.
The drive is spetacular! My car just feels 'lighter' to drive. It revs much faster and wtihout much hesitation. I cannot believe this is my car. This thing pulls and pulls without end. Every gear was improved. On the highway, i can pass people without downshifing to 4th...stay in 5th and go.
RPMs have changed...a bit higher, 12% increase about.
In 4th gear at 50mph, i was at 2550rpms, now with the 3.46 im at around 2950. 70mph at top gear is around 3100rpms
I recommend this mod to any 323/325 manual cars. BMW should have kept the 3.46 diff on the cars!
