Hey guys,
Just wondering how many of you are running limited slip differentials. I'm just wondering if its worth going the extra $1500 beans to add one to the box. Of course, if anyone knows of a less expensive way to go, I'm all ears. I've been thinking of using an Audi 5000 box. Any suggestions.

do the 944 boxes come with limited slip? That could be a good way of getting limited slip and a gear ratio change for the Audi box at the same time. | |

Some of them did, Gary. The 1984 944 that I owned came with limited slip differential, which was an option. | |

For anyone whose interesed....... I just got my porsche transaxel back from Jim Ellis Porsche where I had it cleaned and inspected. the shop forman said it would do if I didn't plan to break the tires loose while driving. Seems it has some good points and some bad ones. I am planning to offer it up for sale as a parts transaxel.
The badnews:
the dog teeth are rounded, the syncros are worn, the imput shaft has been altered ( I presume to fit the 351 it was mated to ), and the shift fork has been altered so as to work with a cable. The trans has never been run with this engine as the engine was recently rebuilt and has never been cranked.
The good news:
The transaxel is an 86 or 87 ( could not discern the numbers ) It is a 930 positraction unit.
This from a shop forman with 20 years experience who knows his stuff and would vouch for the information about the unit. Anyone interested should contact me and I will send closeup pictures of all the info here. this probably should be posted in the for sale section but since you were talking about posi units, I thought someone might have an interest. If none develops it will go up on ebay.

I have a Phantom Grip installed in my box but have not yet run the car. Runs about US$350. Local autocrossers had high recommendations so I figured it would be worth a shot... http://www.phantomgrip.com/ | |
