want to make my C4 a C2

[Porsche964turbo]

I want to make my C4 a C2. I do not like AWD because of its annoying understeer and that it does not take very well to launching. I dont want it to be an american strip layer, but i do want to destroy anything Japanese when it pulls next to me. Now all B.S aside, what will I need besides the tranny itself? Will the front brakes need to be changed? What about the front hubs, shift linkage, or if it applies, computer? Any advice welcome (besides selling the car)

P.S: Anyone interested in buying a 964 AWD setup with low miles?

Sell your car. Buy a C2.

Plenty of folks out there who like the C4. Almost no one will want a C2 that "used to be a C4."

yea, but I already have: 3.8 pistons, bilstein coilovers, big reds, mass air, custom fabricated exhaust, 3.8 bi-plane wing, center-force clutch, RSR cams, and many other small items that are one-off things. If I sold my car, it would meen starting from square A. Also, I plan on keeping this car seeing as the chassis has 193,000 miles on it. Also, I plan on installing low compression JE 3.8 pistons and doing a motronic turbo setup this winter along with completly striping the car of its Gaurds Red and painting it that non-metalic dark grey that Audi has on its TT. This is going to be a fast, good looking, yet understated car. If i knew I could get enough money for my car to buy a decent C2 and do most of my mods to It, I would.

ditto on what Moses said...

Get a C2 donor and put your engine in it.

Put a 3.0 engine in the C4 and sell the car on ebay as a "custom car". Then put your 3.8 into a C2 with a blown engine.

but it would be soooo easy to do a conversion, all I would need to buy would be the tranny itself, and a few small misc. parts. then i could sell my awd for as much if not more than the 2wheel

Might be the dumbest idea I've ever read about on this board.

[Matt Smith]

Not exactly a lot of support for this mod is there?

It doesn't seem too dumb to me. Although I have no idea how to do it, surely a nice compromise would be to keep the 4 bits so you could change back again for sale or whatever. Best of both worlds?

I race against a guy with a 993 GT2 replica built from a 993 Carrera 4S. -I think all he did (apart from installing a twin turbo 993 motor) was remove the front drive shafts. His car can be converted back to 4wd in an afternoon and know one would ever know.

If you're going to add a turbo, aren't you going to want the AWD? You might not have traction issues now, but you will after that!

[Adam]

Once you turbo your 3.8, you'll want your AWD back... especially if it's a daily driver.

Spend some $$$ on the suspension. You'll cure a lot of the understeer.

[edit]Colin beat me to it.

There was an article in Excellence a year or so ago on exactly this "reversion". I know what you are after - and so does the owner of the car in that article. Shaved a bunch of weight off the car and gave it back the driving characteristics desired for a track car.
I'll see if I can find it.

I think you will need to change the nose of your tranny not the whole thnig. I don't know about changing hubs or anything.

Go to http://www.turbo911.com/ and post the question

Or http://www.c2turbo.com/

Good luck

There was also an article in either Excellence or 911&PW (I'll look it up) about how to drive a C4 thru corners equally well as a C2, with some mods to the suspension and a different cornering technique. After they were done, they felt there was minimal difference.

That said....

I'd really be tempted to buy a C2 in the color you want or close to it, and just swap engines and any other parts you wanted. Then you'd have a stock C4 to sell which is attractive to many and a C2 platform for your future desires. Given that you dont like the present color and the desire to change it, the money seems in favour of my suggestion I would have thought.

Just my 2c

Rook in Atlanta was doing a GT2 conversion on a 996TT. They had to change the Tranny and the whole strut assembly. It is completley different. May not apply on a 964 though

[k9handler]

ok....you pay shipping and I will trade you! I know what you are going for...but the AWD feature is better off in your car, so leave it alone and trade me! HA HA....enjoy the car as is!

You don't even need to change the tranny, just lose the driveshaft coupler, remove the front drive system (and shaft housing), block the hydraulic diff locks, and presto! Instant C2! That's why the 964 C4 manual only needs a small separate section for the C2, they are basically the same car. Been there, done it. I do seem to remember that the original Turbo Perfomance Center conversion was a 964 C4 that showed that all the original C4 needed was enough power to make it break loose...

[caliber60]

Porsche964turbo, you are joking.

[CamB]

Ignoring the less helpful posts, it looks like you need to get a really good handle on the differences between the two cars, then make a decision as to whether you should try and simply rmove bits until the C4 becomes 2WD, or if you should replace C4 bits with C2 bits.

Personally, I'd do the latter. But then again, I have no idea of what is involved
