G96 Drawing or Dimensions?

[Paul Proefrock]

I am trying to do some layout work for my build. I am awaiting delivery of a transaxle so don't have a piece of hardware to measure.

Does anyone have any dimensions or drawings of the Porsche G96 transaxle? I have scoured the internet and keep drawing blanks. I can find pictures but no drawings and little if any reference to using them in our GT40's.

Most specifically, I am looking for these dimensions

A) Bellhousing face to centerline of axles​

B) Axle centerline to centerline of rear support bushing.​

C) Centerline of input to center of rear support bushing​

D) Center of input to center of axles​

E) Outer diameter of bushing hub​

Hi Paul,
I’m looking for the same information. I’m also looking for details on the input shaft. Did you find what you were looking for?

The website Darius mentioned has some good information, but no dimensions.

I’ll get you dimensions when I get home

Does anyone have a diagram of the bolt pattern to the engine with the input shaft as a reference?

Not sure if this is correct.

The dimension "D" on the side view should be 3" assuming the bottom dimensions are correct.

Just a point of clarification if accuracy matters, this is a Porsche transaxle right? The dimensions are likely in mm and the rounding errors could be painful.

It does look like 4 of the holes are in a circle. I wonder if the quaife box has another intermediate piece in between.

257.17mm is almost exactly 10 1/8”.

Inches. To clarify. These are approximations. Useful for someone figuring if things will fit, not designing an adapter etc.

I would think all the dimensions should be metric?
