968 box in a 944S2?

[gemmerson]

On a certain well known aution site there is a pile of M030 stuff together with a oil cooled gearbox complete with LSD from a 968 for sale.

With the obvious exception that the box would need checked to ensure its not a box full of neutrals, does anyone know if that would fit into a 944S2 ? Looked at most of the Porsche CD's and parts comparison and 968 parts seem to be interchangable. Just wondered if anyone knew before a bidding war starts !!!

If it's a 968 'box with LSD it will make all the money and then some is my guess.

It can be done though the boot floor has to be relieved I believe. I have been told that the 968 'box is both stronger and weaker than the 944 'box and I am therefore not sure if this is a good mod or a bad one.

Anyway I suspect several people with open diff 968s will end up bidding on it.

I have a friend who fitted a 968 box to his 951 so it can be done but I'm guessing if it's genuine that the bids have doubled while we're reading this.
Good luck!

A 968 box will fit in an S2 but will need floor modifications, the spare wheel well is larger in the 44 than a 968. A 968 box is a sweeter box than a 944S2 IMO, but arguably has 1 to many gears!

The m030 parts on ebay are of an 89 944 turboS not a 968 !!!

Here's a 968 box on eBay, it's priced a bit over the top considering there's no warranty:

A 968 box fits right into a S2/turbo and there is no modifying of the shell required at all, at least on LHD cars.
Apart the gearbox itself are required the right 968 driveshaft, the 968 gear shift linkage, relay G22 (FCU unit from 968) and 968 ABS control unit. Some brain use may be necessary with 944/968 wiring diagrams to make the speedo work using the two latter parts.

As has been said previously.. The M030 goodies are from a 944Turbo.. NOT a 968..
This is where it pays to correctly read the add....[8|][8|][][]

This is correct, and also contrary to popular myth you don't need to change your torque tube to a 968 one (although a 968 torque tube cuts the labour required to change the clutch by 40% so is probably a good upgrade if the opportunity arises). Early 944's with metal fuel tanks will need some modification to the fuel tank to clear the box, or replaced with a later plastic tank. I've read the 968 box is a nice upgrade for S2's but not so much for a turbo as the ratio's are all wrong, especially 1st and 2nd gear.

LSD boxes on ebay (or anywhere else for that matter) seem to fetch rediculous money on the basis that the LSD will almost certainly need a rebuild. I've read that 944 turbo LSD's are only good for about 40k miles before requiring a rebuild. In my view you're much better off simply replacing your the diff on your current gearbox that you know and love - assuming it's in good nick. This will work out to be a little more expensive than buying a 2nd hand box, but when you balance that against the risk you might have bought a bag of nails and that the LSD will almost certainly be in need of a rebuild it is a very sensible option. You will also have the opportunity to install a far superior aftermarket LSD unit or even a Torsen diff which is supposidly a better unit for the road. The oil cooler is a nice touch, but i'm sceptical as to if it is really needed if you're not a hard core tracker. I'm sure the non-cooled gearbox is perfectly fine for the track 'dabbler', especially with the modern synthetic gearbox oils that are in a completely different league to the oils that were available 20yrs ago that the origial box was designed to put up with.

Sorry about the title mix.............read the 968 bit and then didnt read the rest of the ad............that will teach me. Still usefull to know about swapping a 968 box anyway...........well it was for me.

I would imagine that the basic gearbox housing already has plug holes which one could use to tap in an aftermarket oil cooler?

This gearbox oil cooler - does it use an oil pump to move oil around the cooler, or does it work on the basis that the hotter oil rises to the top, and therefore if you plumb the cooler into the highest and lowest points of the gearbox then the oil will circulate through it? Or does it take off the oil from a known high-pressure area of the 'box (pressure caused by the movement of the gears) and return it to a lower pressure area (i.e. a built-in pump, effectively)?

I've never heard of such a thing, but can imagine that any would be viable solutions.

I don't know the answer to any of those questions, but the cooler is just a pipe with fins on it and I suspect it's either temperature or pressure driven.

It's a pinion-driven oil pump.

A dedicated unit?

Gosh, that's posh. Porsche at it's best, I guess. They don't seem to do things on the cheap, do they?
