Turbo 4 speed to G50
 

Hi all I am trying to get measurments or a diagram on machining G50 bellhousing and input shaft to fit it into a 1981 930 turbo I do not want to cut the torque tube... does anyone have a diagram...

I did on my 78'. Everything will fit. I will send you some picture when back home. I installed removable gearbox mount, spacers on the torsion bar and i made more space under the gearstick (less than an inch) to fit the g50 gearstick from carrera 89'. At the end the only modification i did on the car was this little box i made under the gearstick. I will check how much i cutted from bell housing.

Hi Mario did you find the pictures and measurments to install G50 into turbo 4 speed...

29mm max

Hi Lite 75.. is this of both bellhousing and input shaft are there any diagrams or pictures that would show the total swap...

yes, both. 28mm should do it for you unless its a 75-77.

what if 75-77 ?

Thanks

They will need additional room, either move the motor back or notch the torsion tube. 75-77 have the motor mounted further forward compared to the later models.

This is accurate. We usually say 1.1mm. That's how much our 3 piece mainshafts are shortened.

Matt

You mean 1.1"?

Yeah...that.

Thanks, I know the engine is mounted 2.5mm (as I am informed) closer to the center of car compared to a 78-89, what I ment was, do we have knowledge to the additional measurements that has to be removed on the shaft, housing etc. to fit a 75-77 OE mounting?

I was under the impression that a G50 bellhousing could be set up and shortened to fit a 75-77 without having the engine moved 2.5mm backwards
