I have an 86 951 with Huntley 2 turbo, MAF #4,ARC2 with recently developed transmission problems. Mechanic says need used or rebuilt one; I wondered if a 968 6 speed LSD transaxle could be used, and if its tuff/robust enough? any thoughts? thanx

here's some info if anyone wants to see the gear ratios:
1991-1995
NA, Cab, CS used G44/00
Turbo S used the G44/01
1st: 3.182
2nd: 2.000
3rd: 1.435
4th: 1.111
5th: 0.912
6th: 0.778
Rev: 3.455
axel ratio: 3.778
...the 968 uses "Torsen" LSD
1986 944 Turbo, gearbox: 016R
1st: 3.5000
2nd: 2.0588
3rd: 1.4000
4th: 1.0345
5th: 0.8286
rev: 3.5000
axel ratio: 3.3750
let us know if it works!

I have heard that 968 G-box, has a totally different speedo drive system compared with the 951. Dont know if this is true though.
Maybe someone could verify this for us
si 91 951s

The 968 trans doesn't have a speedo sender. The 968 gets its signal for the speedo from the ABS unit (after all, it's counting revolutions for all four wheels all the time).
Someone has a solution to allow speedometer usage with the 968 trans in a 944 car, involving using the ABS brain. Anyone?
UPDATE
I was looking through the 968 and 944 wiring diagrams, and the 968 gets its speedo signal from the DME box, but the main ABS wiring harness is a different number for the 968 vs the 944. I seem to recall that Gary Stone's solution was rumored to cost a couple hundred bucks, likely true if you have to mimic something found in the DME.

I've got a gearing chart on my website at http://members.rennlist.org/951_racerx . It lists all the gear ratios and the resultant speed in each gear.
Supposedly Gary Stone, the guy that had a 968 turboed by Kelly Moss racing has a solution. His car was featured in Excellence a couple of years ago. Also some guy mentioned in one of the other threads has a solution as well. Good luck - danno
