915 gearbox

[Bugat5speed]

Hi Mikey,

in fact it was the 901-gearbox that you discribed.


Hi Turbo Haraune,

the 915 easily stands up to 300 PS and 350 Nm of torque. We are running it with Subaru Turbo engines with that power and it is perfect.
The 901 and 914 are also ok, but stand less power/torque. I have customers with 2.8 type 4 engines with up to 220 PS and torque near to 300 Nm with 914s, but they do not have a turbo and by this the torque at higher revs.
We offer conversion parts for both, 901/914-gearboxes and also 915-gearboxes. For 915s we have short nose cone (-20 mm), traverses and axle flanges. Have a look at our site www.bugat5speed.de and look for Umbauteile Porsche-Getriebe (for 901/914-conversions) and look for Projekte for 915-parts

This new nosecone for the 915 box... how much fwd can i move the box from its original position before it interferes with the torsion tube?

I want the gearbox to be 50mm fwd of the original position..do i have to cut the tube?

Reason for this is that the subi motor interferes with the back of the car if not moved fwd..!

What about gear linkage?

Hi,

as the nose cone is 20 mm shorter the distance to move forward is 20 mm. By lowering the position of engine and gearbox you can find another cm. My colleague always cut out half of the torsion tube in the past, but did not adjust anything at the nose cone. He had 5 mm space between the nose cone and the half tube then. His engine/gearbox is lowered by this 1 cm.

He told me that with the new nose cone it´s only necessary to grind the thicker ends of the tube and make them flat. It´s anyway better to drive with spring legs in such a car, than with the torsion bars.

For any other questions please contact me directly!

Cheers Martin

hmm... Thanks guys. I'd rather be corrected then keep going being wrong.

I love your direct translation of 'Federbeine'
Strangely it translates to 'coil-overs', but what the heck

I have only removed the plate of the torsion tubes where the 2 gearbox bolts are attached/welded on. With only a few mm's clearence, my early 915 gearbox is now with its beel housing in the same (original) position as the original type 1 gearbox was...
So I never really have understood the neccesity of shorter nose cones...
Drove it even on the track, but nothing touched or interfered. I just need the syncho's replaced

Hello bugat5speed, will you have an english version on your site soon?

[Bugat5speed]

Hi,

there will be an English version of my site in a few months time. The software with which the site was made only allows a single lingual version. The software will be updated soon and then a multilingual version will be possible also (and will be done).

Wally, it´s nice for you that your English is better than mine. Congratulations on it.
Are you sure talking of a 5-speed 915-gearbox being in the same position as a Beetle gearbox? Nothing is cut off at the gearbox, or the spring tube at the frame? The 915 is even longer than the original 901-gearbox with a short nose cone. A 901/914 with my short nose cone has 10 mm space to the spring tube in the front and in the back it is there where the bellhousing of the type 1 gearbox ends.
Can not imagine what you wrote here. Have lots of customers who have worked with 915s in the past and who are all expecting my new 915 nose cone. Are they all on the wrong way, or do they like spending money without a use of it?

My remark was in no way meant to be offensive Martin. It just read sort of funny and I hope a little humor is allowed in Germany as well as over here

I just described MY experience from doing the swap. I am in no way an expert to this, as I have only done my own conversion.
In the past I have described my 915 swap in detail with pictures, which sort of let you see, what I described
The info is right on this site:

http://www.germanlook.com/Forums/sho...&highlight=915

I have had the same engine in the 1303S trans and with the same BAS exhaust header, I had even a little more clearence with the 915 then with the 1303 tranny. Not kidding. You may not believe me, but thats not really my concern.

I have only grinded away the mounting plate where the original two tranny bolts had been attached to. That gives a fair amount of additional clearence. The torsion tubes themselves, I have left alone, as well as the nose cone. The clearence with the torsion tubes and trans is however only 2 or 3 mm's, but I have raced this set-up hard on our track at Zandvoort and with many drag-style starts and nothing touched ever!

Also, my trans is a 915/40, so yes, its a 5-speed and it even has the 100mm CV hubs, so any 100mm VW Bus T2 CV will fit (I use T3 axles). And this is stock from the (porsche) factory.

If you have any questions Martin, please feel free to ask them.

Mit freundlichem Gruss,
Walter
