First off, I would just like to remind those who didn't understand fully, I am NEVER selling this car-I dont care if I become the richest man in the world, I will keep it untill either the car or me or both expires.

Second, useless comments like the example above are not appreciated- If you dont believe in my cause, don't say anything. This conversion is going to be done by me and me only. I am only paying for the parts to do it. Im sorry if this person dosen't like what I am going to do, but judging by his comment; I have made fecal matter that is more inteligent than he. So if you want to give me advice (whether or not its what I want to here) I thank you. If not, I will see you in my rearveiw with my speedometer gauge inching towards 200 M.P.H
Peace out

You posted your request for comments in a public board. By the board's nature, there will be positive and negative comments. If you truly believe in your case, ignore the negative comments, do what you want to do, and forget it. Your car, your money, and you don't need to ask for permission.

But you did ask for comments, and you can't just ask for and expect only positive comments.

I happen to be very interested in this thread. Hopefully you'll let us know how it can be done. I would like a 964 next, and there seems to be 10 C4's for every C2 964 that comes for sale around here. I simply have no interest in an AWD 911. Hopefully it turns out to be as easy as "69 911s" says it is in his post. Good luck.

Is it true that the 964 C4 is really a front wheel drive with power applied to the rear when needed? If so, I understand where you're coming from. Keep us posted!

Elombard · 07-01-2003, 02:36 PM

Good point Rob. I too wuold like a C2 and have 0 interest in a c4 and there are lots of C4s out there ( I wish there were a way to convert a Cab to a coupe :-)) I will start watching more carefully. I dont care if it ends up a Bastard car, I would buy it cheap wrench on it enjoy it and sell it cheap.

You asked for comments, how useful the comments are is up for you to decide. I said I thought the idea was dumb (IOW, don't do it). I stand by the comment.

Are you sure about that? That's a pretty harsh comment coming from someone that has been a member of this board for all of 3 days. I'll match my intelligence against a 22-year-old construction worker any day. I hope your spelling isn't any indication of what I'm up against. Name the stakes.

hallo
You can remove the Axletube and Front-diff. with Axles . Pull the Plug on the AWD valves in the Trunk ( so you can leave the Hydraulics ) .
You need a 2 WD shiftlinkage and the Frontbracket ( goes on the Frontaxle and holds the linkage ) You need the Tube below the Shifter
in the Tunnel and the Bracket to hold it ( you can not buy it from Porsche
look for a wrecked C2 ) . If you are happy with it look for a 965 Turbo Gearbox or a 6 Speed 993 with LSD .

A 964 C4 has 31% of power to the front and 69% applied to the rear. It is the only true AWD that Porsche makes. The 993's and 996's use a totally different system.

I have a C2 and have considered getting a 964 C4. All this sure makes theworld go around.

My thoughts...

I would try talking to some others that track their C4's to see if your driving style can be modified to suit. I'm assuming you're not really that interested in drag-racing otherwise you wouldn't have bought a 911... right?

So I've driven both C2's and C4's and the driving required to get around the corners is different.

Does the C4 understeer more? Yes, but in my expereince only upon turn-in. During track out/apex acceleration they understeer LESS because of the weight and power in the front.

IMHO the C4 is still faster. WHy? WIth the AWD you can enter the corner faster and trailbrake to overcome the understeer, and since you can get on the gas harder and earlier, they exit faster.

Before you sink the big bux into switching the trans, you might try a little more trail-braking (not for the faint of heart in a 911) and get on the gas even before the apex, hard, and steer your way out...

Seriously..

Jim Smolka · 07-01-2003, 05:22 PM

There have been reports that the C4 has been able to eat up transfer cases when the are tracked - raced. I have been following this post since I have a bought a slightly bent 964 C4. I would like to make it a track car, but it may be best to part it out.

I was under the impression that C4s had a viscous center differential. I read somewhere that they ran 5% power to the front wheels under ideal conditions, with a maximum of 40% to the fronts under extremes. Perhaps I've got it mixed up with 993 C4s...

Does anyone know for sure?

Personally, I'm thinking seriously about a C4 as my next 911. I have had long-term AWD cars and loved the grip in the wet and uber-grip in the dry.

Victor · 07-01-2003, 05:49 PM

Hey Adam, I think DDR964 (Brett's car) is for sale. If you can stand the color.

expat · 07-01-2003, 06:25 PM

Ok guys dont upset me...I've just bought a C4 yet to be picked up.....

Anyhow...Chris Streit is correct, driving technique in the C4 is different and with correct understanding and application can be equal to C2's in cornering. I will definitely dig out the p-mag article from last year on this and get back later today with an explanation.

(sorry, hope I'm not robbing your thread!

)

Cheers

I think thats the system in later C4's. The 964 was/is fixed AWD.

If you buy a C2 it will come with an engine....

Put it in your C4 and exchange them out. You also know where your engine has been after its done.

69 911s · 07-02-2003, 04:49 AM

Chris,
I had so much understeer that I was balancing myself against the weight of the wheel in certain harder turns, car control was completely different and 4 wheel drifts were just about impossible, with a performance aligned, corner balanced, 18 inch wheeled, H&R sprung C4. That's why when the DM flywheel puked I left the sleeve to the front drive off. Changed the whole personality of the car. That's why I went to a light early car with only RWD. The C4 was a great car, but I couldn't take the track driving characteristics. Too much like a Golf on steroids.

1fastredsc · 07-02-2003, 06:21 AM

Although the design of the later AWD's are different, the idea of removing the front it essentialy the same. My old boss just did some mods to a 996 tt and all he did was remove the front drive assembly, changed the turbos, and chipped it with a map for the turbos. It put out 550 at the wheels.

jrb964 · 07-02-2003, 07:28 AM

Chris from Glasgow is absolutely correct. The 964 is a true AWD, while 993 and 996 are viscous couplings.

Porsche964turbo · 07-02-2003, 08:53 AM

I am still looking for somone to buy the awd setup in my car. once that is sold, I can get the 2 wheel drive tranny of my choice. I want a 993 six-speed box, but they are around 3,500$. I know that if I wait, I can get around $3,000 for my tranny. so my idea is to buy a 964 g50 without the limited slip and then with the extra money fit a Quaife limited-slip unit in there, then I will never have to worry about grenading the diff.
So If anybody is interested in a low mileage box that was run on red-line synthetic oil, drop me an E-Mail.

Alright, this is going to be the last post that I am going to waste on this person. Numero uno, I have only been on this post for a few days because I actually have a life out-side of computers, E.G working, racing, getting laid, etc....
You defenatly are trying to match your intelligence against a 22 year old construction worker because your still talking. speaking of age and occupation, you don't have any put down. This leads me to believe that you are probley some high-school kid that is on this post speaking about his daddy's car (sooooo cute). And my spelling is a little off isn't it? I'm sorry, I forgot that you won the spelling contest at school.
Oh, and one other thing, its not inteligent that I would bring my car up to 200 M.P.H? It dosen't do 200 yet, but I get to about 178 or 180 given the air density and temperature. This is not a question of intelligence, but a question of balls (anybody who has seen me drive knows I have them). Im just saying, don't get mad at me because your car or your daddy's car is slow- I have nothing to do with that. Now all B.S aside, I am not going to post anything more on this subject, I am trying figure out how to make my car 2-wheel drive....Hence the name "Want to make my C4 a C2".
