I have been keeping up with this thread, and to this day, I am still unsure if it makes economic sense to turn a 996 Turbo into GT2 spec.

Being married to a lawyer, putting in rear seats in my GT2 is totally out of the question. And anticipating the need for a more familt friendly vehicle, I can't help but come to the conclusion that if there is somehow a way to make the Turbo a good old fashion honest to goodness RWD, it would be a great successor to my GT2 when the lease is up in 2009.

So, let's say I do the following:

1. Remove front half shafts, front diff, and drive shaft.

2. Replace front and rear suspension with OEM GT2 bits.

3. Install rear diff from the GT2.

4. Replace the wiring harness with GT2 wiring harness.

My question is, is there a cheaper way to permanently remove PSM from #4 and have the Turbo behave like a real RWD?

And yes, I can drive my GT2 sidways with my eyes closed just fine. PSM was the reason I sold my Turbo, and if there is a economical way to remove it, then it's built in rear seats makes the Turbo a economic family car.

 

Just remove the ABS/PSM fuse.

 

1. yes
2. you can do that or just get aftermarket coilovers like me and dial it in to GT2 spec alignment
3. It's a good idea to install a LSD (next on my list)
3. No need to replace the wiring harness, you can either pull the fuse/s or just turn off the PSM.

My 03 Turbo PSM would turn itself back on if the slip angle was too great.

Wouldn't pulling the fuse trigger all kinds of faults in the computer?

 

How would this transition do for a 700HP? I am interested to do this.

 

PSM only turns on when on the brakes. Just like 997 GT2. There aren't too many conditions in which the slip angle is there and you're on the brakes.

 

Well, you'll find that the car is a little quicker with the loss of the 80lbs off the front of the car. The car's steering is more precise and nimble and you lose some of the understeer plowing from the front.

 

it will take much more than aftermarket coil overs to get a 2wd turbo to handle remotely similar to a GT2.

 

And ive said it countless times.... At least with my experiences with both, they feel like completely different cars, and my turbo had no sunroof too!

 

Coilovers + GT2 spec alignment + corner balance = close enough to GT2 handling for someone like me...

 

GT2 has no PSM, only ABS. That is why I got it, and why I got rid of the Turbo.

PSM turns itself on, in my experience, when you are approatching the 45 degree slip angle.

I never had to countersteer the Turbo because the car would always correct itself, which is boring.

 

Which is why I would change the carrier, control arms, etc if I was to go this route.

 

A little help please...change the carrier?

 

AFAIK, the thingies that attaches the front wheel to the car is different on the Turbo than the GT2, because the Turbo needs to accomondate the half shafts on the front wheels, while the GT2's do not.
