As per title, few questions for those who have converted their car to 2WD by disconnecting the cardanshaft ( or whatever it's called... ).

1. How many miles since the conversion?
2. Any problems regarding the transmission?

Has anyone gone the hard way, ie. removing the front output completely from the transmission? It can be done with Motorsport parts, expensive though.

 

A 996tt can be converted to full RWD with 0 cost, only about 2 hours of your time. PLENTY of threads here on that, do a search...

 

1. 8000 give or take
2. No

3. thread closed, please

Very easy to do.

 

I'm aware of this, the question is about durability. There's a rumour going on that transmission will eventually fail with this kind of conversion and I'm trying to find out if it's just a urban legend.

Thanks justinn, anyone gone over 20k mls?

 

Transmission failing? By reducing load? never heard of it...

 

I've never heard such a rumor, where did you hear it from?

 

If I recall correctly you will have PSM issues if the car is driven hard and you don't change the ABS hydro unit for the GT2 part.

 

Not if you turn the PSM off........ Of course with it on, one rear wheel will constantly be freely spinning under cornering so you won't go very fast without interruption.

However that is not transmission failure, nor is ABS which can fail on AWD as well.

I do believe from personal experience that you will eat away your gears way faster, our open rear diffs were not designed to put power to only 2 wheels. But this is track stuff. I can't imagine anything being a problem on the street other than traction.

 

Apparently PSM can not be turned off completely without replacing the ABS hydro unit.

 

unplug your MAF, trigger the PSM ABS lights, plug back in the MAF, and try that might be off then

Yes it can, just takes some tricky wiring techniques. I know some people (shops) that have done it. I just haven't gotten around to it yet.

 

there are tons of people converted to 2wd no failures caused by conversion alone so far

 

My car has been on and off as a RWD (mostly RWD) for teh past 2 years or so.

It is not a full conversion in that it's only a cranshaft removal.

My latest round of mods have me considering AWD again. The car has No traction in 1st and 2nd and I think the AWD will help hook a lot beter.
