914World.com _ 914World Garage _ Downfalls of the 915 mag trans

Posted by: echocanyons Sep 7 2003, 04:14 PM

I am thinking about picking up a 915 trans but it is an earlier one (75) that is magnesium not aluminum.
other than strength and wieght what are the disadvantages?
My goal with this will be a sideshift conversion for a higher HP powerplant

Dont let the mag case catch fire. 911 perf. handbook does not really go in depth as to the differences/advantages of one or the other. I think it is kinda spendy to convert a 915 box to mid-engine usage..

Kelly.. stay away from them. The pinion bearing race has a bad habit of getting loose and spinning in the case. Sooner or later this causes ring and pinion failure. We are starting to see this same problem on the later aluminum cases also...

Two candidates on EBay less than a day ago. Wait until you see the show box (for the German Autofest)
