So, what does a decent used 930 box go for anyway? Not with any tricks done...just known good used. And on the same note, whats the cheapest you could get one for? Say, still usable but needs a rebuild. I have a rear engine v8 project in my future, and the tranny is still the missing key, space isn't an issue, so I figure I could go 930, or ??? will need to handle lotsa torque ~400ish...

Thanks,

Tony

oh yea, the ZF is a great choice, if you can afford one: STARTING bid of $5000.00

another one, STARTING at $8750...ouch

I noticed both are claiming brand new, so I'd venture to say that a decent used one is in the 2K range

I buy 930 boxes in this area with LSD's for around 1500$. Normally second gear sync's are toast. It was very popular in our area for shops to yank the 930 box and install 915's so we have them floating around this area.

Scott at RH does not run a 901 box. Hasnt in a few years now. He runs a 930box.

The G50 would be fine if you didnt have to run 20inch wheels/tires with it to get decent ratio's out of it (it isnt that bad.. but.. 17's are almost required)

I like the 930 box. Sure it is more work.. figure 7500-8000k for everything.

Guys,
I have seen a lot of talk about the Getrag 6 speed boxes being used on the european GT40 relica's, as well as the Audi 1E 6 speed box, both mounted to Ford 302's and 351's.... Does anyone happen to know if either of these boxes = the Boxter S box under a different name?

Ok,
Lets see if I can do this....
This is the Audi 01E box, supposedly the same as the 968 box, according to this website... http://elektro.cmhnet.org/~charlie/photos/...s/01E/ind3.html

Problem with the Porsche box:

NO provision for a starter. It was mounted to the bellhousing up on the engine.

I just barely have time to read right now.. you sent it to the right place.

Andrew.. too much work for little return. Look at what that guy went through to have a Boxster box mated to his aircooled 6 cylinder.

to do this properly, you'd want to have fixtures made so that when welding, everything is lined up, the fixtures alone could cost a small fortune unless you get access to a machine shop. Then there is the question of how compatible the two different materials are, both transmissions have had years to get oil soaked into them which will make welding a little harder.

Is the input shaft on the 944 gear box the same as the 901 box?? I'd imagine it being a bigger diameter, this means you'd be "stuck" using 944 clutch parts, which could be good or bad depending on how much they cost and how much torque they'll take...I'm guessing HP/torque wise they'll be fine due to all the high HP 951s running around.

For doing a boxster transmission > aircooled engine, I'd be willing to help or make the needed fixtures for free if i can get a completed transmission out of the deal (IMG:style_emoticons/default/smile.gif)

From what I have seen it’s a toss up between the Pantera ZF and the Porsche 930, in terms of power handling ability and cost. To have a 930 gearbox modified to work in a 914 ready to install will run you about 9,000 including the cost of the gearbox and you only get 4 gears. The Pantera needs no internal modification to be used in a 914, just need to purchase bell housing to mate to desired motor, and you will have 5 gears for 9,000. My choice was the Pantera ZF.

Regards,

Turbo Paul.
