Man, no offense to any of the auto guys out there, but putting an auto tranny on a rotary engine is like putting ketchup on a donut...

I meant is it an AUTO Driveshaft? I am trying to see if the info I was told is right......an NA Automatic DriveShaft will fit a TII tranny AND an NA Diff(such as the GTUs 4.3 difff) I thought about it when I did the TII swap into my GTUs.....I never got an answer and I didn't want to buy a Driveshaft....so IS THE SECOND DRIVESHAFT AN NA AUTOMATIC DRIVESHAFT? the first is a TII, the third is an NA....

Is it just me, or is there very little difference between the T2 and the NA. the NA is a bit longer, but i thought it was going to be REALLY thin compared to the T2 drive shaft from the way the T2 people talk. As it looks, i think i might be okay with the NA drive train and my 200hp project.

Thanks for the pics!!!

Yes, NA with a manual tranny, and manual driveshaft, all original, and still going strong at 193,000 miles, even with the abuse I put on it...

Hehe, I all but snapped a uni off my N/A manual driveshaft.

Is was worn a little bit to start with (only 127,000km's... but i suspect bad tranny/engine mounts did the damage) but then after a little whee burnout it was hanging together by the thinest of margins...

shaking and carrying on even going the ~20km/hr on my 1km trip home.

only found out how bad it was the next day.

Bloody lucky it didn't snap, moral of the storey? Make sure your uni's are in good shape.

you are supposed to have the third Driveshaft if you have a 5spd NA..........I THINK the second one is an NA AUTOMATIC driveshaft while the third is a TII driveshaft(as he said in the beginning.) Very very interesting car you have there.....care to post some pics?

That's from another thread, referring to the skinny driveshaft (bottom in this thread's picture).
