Tought about 3.15 with G260

[Jim Lepage]

I need a diff and a local guy is selling a Z3 3.15 Torsen really cheap.

Will I cut all the fun I have (3.73 open with chipped M50) driving my car by swapping to a 3.15 ?

It will definitely be slower. If you don't do a lot of highway miles and are going to stay stockish M50, I'd pass on a 3.15. My M50/G260 is happy with a 4.10, I wouldn't go for under a 3.73 unless you are sick of shifting and want more of a cruiser.

Buy it then sell it.

With a G260, I agree. I have a 3.15 Torsen, though I also have a ZF320. This car will see a fair amount of highway miles; at 75mph I'm turning ~3500.

buy it, and proceed to turbocharge.
