930 Transaxle upgrade

[Steve26]

So I'm thinking about putting a 930 transaxle in my car and looking at the different ways to mate it to the Ford 302 and while doing this I saw a great idea on the forum and now I can't find it. Someone here milled the bell housing completely off and attached a Ford aluminum bellhousing that had been modified to fit the 930. Does anyone know where that can be found and if the guy ever finished it? I think this is a fantastic way to make this adaptation because you can use all Ford clutch parts and starter. Here are some pictures of the guy's conversion. Please help!

I can't speak to this particular project - but I would be willing to bet that the folks at Quick-Time Performance are already looking into it...

They already have a bellhousing to go from the GM LS engine to the Porsche 944 (Torque tube) and some of their automatic bellhousings look like they would be good candidates for modification..

Hi Steve,
Yes that is my set up.
If you need dimensions and photos I can provide. When I take the gearbox out again, I'll take some photos of the individual parts if you want, although it won't be for some time.
I can't take credit for doing the conversion myself. That was John Wisher, but I did purchase it from him and yes, I have a full size clutch, flywheel and the starter points the right way so no clearance issues with the horseshoe.

rockonsmileThank you Martin. Can you give me the dimension from the bell housing face (where it mounts to the engine) to the center line of the output shafts? Also, the dimension from the bell housing face to the mounting point on the transaxle? I think I'm going to be able to buy a transaxle on Monday but would like to know some of what I'm getting myself into first. Thank you for responding.

By the way your build is BEAUTIFUL!!!!! You are doing a fantastic job and your attention to detail is superb...

Thanks Steve,
The bellhousing dimension you are looking for from flange face (engine side) to flange face (gearbox side) is 3 3/4".
Hope this helps. Any more questions, just drop me a line and I'll try to help.

That helps greatly, thank you Martin. Can you get the dimension from the bell face to the centerline of the out put flange? I should be able to buy the 930 box this afternoon.

Here's the only other measurement I took before I put it all together to trial fit. The spirit level was placed across the bellhousing flange to get an accurate measurement.
Cheers,
Martin

 

[Steve26]

Thank you Martin, If at some point you can measure from the centerline of the axle output flange to the bell housing face that would be great. How far are you from driving your car?

Maybe you guys should start a new thread entitled "930 Transaxle Measurements". I know that I have had two people PM me about 930 measurements in the last couple of years.

 

[Steve26]

Hi Ron,
As soon as I get a 930 box I will take all the important measurements and post them here wherever you think they should be. Are you feeling any better?
Steve

 

[Ron Earp]

That would be a good idea to post them up on their own thread.

I've got a fever but I do feel better than the last couple of days. Can't work though, just sit around.

 

[Martin]

Hi Steve,
Measurement from the bellhousing flange (engine side) to the centre line of the driveshaft flange is 9 1/2".
Is that what you wanted ?
I am hoping to be close to finishing the car by summer 2010, but we'll see. I'm not putting myself under pressure to finish it.

Martin

 

[Steve26]

That is exactly what I needed, thank you so much for your time and help. That's about an inch longer than I can live with, I need it to be about 8.5".Do you think there is anyway to make that dimension shorter?
Steve

 

[Martin]

Hi Steve,
I doubt it. The input shaft needs to be in the correct position relative to the engine spigot bearing and clutch frinction plate spline plus the clutch assembly is already a tight squeeze. My set up has been working in a forty already utilizing the mechanical clutch release mechanism but I'm having a little trouble getting a hydraulic release bearing small enough to replace it. I haven't looked that hard to be honest so I'm sure I'll find a solution, but in short, I think the bellhousing has directly replaced the amount of material machined off the front of the Porsche box, so I wouldn't want to take another inch off or I would think you would get other issues.
Glad to be of help, good luck with your project.

Oh shite, Ron has the swine flu.....run away!

Sorry to hear you're under the weather. I just got back from 10 days in San Diego and have come down with something too. I've been telling people I just came back from a week visiting my pig farmer cousins in Guadalajara but nobody seems to think it's very funny.....

It fits a Gen I and II as well.

If anyone is really interested just give Quick Time a call. They now have the 944 bellhousing because one of the guys on our 944 hybrids boards called them and worked with them to get it designed. He supplied them with measurements of the torque tube and the dimension required for the bellhousing depth. They are willing to work with you to develop new products. I have a stock Chevy bellhousing with an adapter plate on my 944 but will be buying one of the new Quick Time bellhousings now.

 

[Steve26]

I will call them when I get my trans axle, it should be here next week. The goal would be to make the 930 conversion like a ZF in that the bell housing would be the adapter and you would use the standard Ford flywheel and clutch parts. It can be done since Martins is set up that way I just need to get all the measurements to confirm how to do it. In the last three weeks I have found a few 930's for sale and the prices varied from $1800.00 for and open diff to $2500.00 for the one I bought with LSD! This is not expensive and if you can do the conversion using all the Ford parts and a "new" bell housing its the way to go as far as I can see. I'll call Quick Time after I get my trans axle.

Steve,
One thing to note is that the input shaft spline will be different on the Porsche than the Ford, so if you are using a Ford clutch, as I am, you will need the spline changed on the friction plate to mate with the transaxle.

Quite true... Also the pilot bearing will most likely require some attention..

Not quite sure if this is relevant here because i do not know the porsche gear box designations.

It might be of some interest as it looks to have a good torque rating.
