Dollar Amount for C4 to C2 conversion?
Seems like there are a few C4 Widebody 964s for sale. Knowing that they are just fine the way they are I am still curious....
I know it's expensive, but what is the actual $$ amount for a C4 to C2 conversion?
Thanks.

I think it depends on how faithful you want the conversion to be. Barest minimum is to change the gearbox from a G64 to a G50. But then you've got all that unwanted weight up front in the form of the front diff and drive shafts and wheel carriers.
Not to mention the electronics for the PDAS which will get all upset if you remove the diff locks. Then you've got an ABS system which may be unhappy about the PDAS removal.
And having spend $000's you would probably want to commit suicide through the realisation that you would NEVER get any of it back, as well as throwing away what the original C4 was worth in the first place.

Not if you want to do it properly. Cheapest way of doing it would be to get a 964 turbo and swap the engine - but then you're de-valuing the 964 Turbo.
As a example I was quoted 1800 Euros to swap a 964 turbo engine with a 993 NA engine on an exchange basis - this was before I came to my senses . I was also quoted, by the same shop, between 5000-9000 Euros to convert a C4 to C2 - the lower price was for a stock C2 gearbox and the higher price was for a RS gearbox. Biggest cost will be sourcing a G50 gearbox. I personally don't think it's worth the effort/expenditure - I'd only consider it if my AWD system broke in such a way that it would be more economical to convert to C2 spec.

NB body chassis with WB panels is great if you want to fit fat tires. I really don't see why my method would be considered not properly. If you're taking something stock and transforming it to something else, might as well start with a low cost C2.

Sorry what I meant was if you use genuine Porsche parts, the parts cost alone makes swapping out a turbo engine a more economical proposition IMO. Obviously it will be cheaper if you use non-genuine FRP parts which is what I was alluding to.

Getty design carbon fibre Kit (front and rear fenders, both bumpers and rocker panels) goes for roughly 8K. Add install and paint. I would say 11K once your done. Glass fiber is cheaper. I would ask Geoffrey since he started his race car project with a regular C2.

If it were me and I wanted a widebody, I would start with a C2 turbo and install a N/A engine and N/A trailing arms. It will be less expensive than converting a NB to WB assuming you wanted factory body parts.

Why, because less hassles with body panels fitment, but how about price difference between C2 turbo (91-92) and regular C2.

A bit off the topic -- but will a C4 drive ok if you simply remove the front driveshaft?
Does the "middle diff" sense there is no traction to the front and lock up and does that make all power go to the rear -- and would that leave the rear diff with its locking mechanism all working ok?
Is it possible to permanemtly lock up a C4 tranmission so that it will work ok as a rear wheel driver only.
and... no... I am not thinking of doing the above my C4 is well sorted and after much work it does not oversteer (except at very low speeds) and it is (apart from rubbish air con) my favourite car

Michael,
The short answer is ... NO. If you disconnect the front driveshaft there is no drive whatsoever to either axle - the car goes nowhere. The mechanical torque split seems to allow all of the drive to go to the axle of least resistance, i.e. the disconnected front. I had first hand experience of this when some bright spark wanted to do exactly this in order to run the car on a 2 wheel dyno and he was somewhat red faced when he couldn't reverse the car off the ramp!!!

PS. The viscous coupled centre diff on a 993 acts completely differently. There you CAN disconnect the front to get 2WD on the rear.
