Im lookign for something less aggressive for my DD 328. I am shortly going to install the support bracket on this 3.91 so problems with the diff bolt wont occur. LEt me know If there is any interest.

Straight up trade if your 3.15 is in great condition. If not, I will need +cash depending on condition. Looking for something local (LA area), but im open. Let me know

im not quite sure at 70, at 80 im pushing 4000rpm, top speed calculated to be around 130

Yes, it is a world of difference. They say aggresive gearing = poor mans forced induction. it drives much differently than a regular 328. Id reckon i could hang with a stock e36 m3 till 70 or so, Im lightly modded.

4 or 6 bolt flange?

Can you deal with down time? Or would I need to send the 3.15 first.

I really cant deal with much down time. il already driving my moms 528 for a week waiting for my AA dsb. Cant go on much longer, thats why i prefer local.
