Many of these cars have already been converted to a more conventional (single plate) clutch system. There is also a large number of tech bulletins for the G-50 clutch system to '89; I don't know how many of these issues were resolved by the time your car was built. Without knowing your skill level, and your resources (tools) its hard for me offer guidance. You'll need a repair manual and the only manual available for your car is the factory manual (very expensive, and not for beginners). You'll need a hydraulic floor jack, jack stands, 8/10/12mm triple square tools, complete set of tools (metric wrenches, sockets, etc.), and a torque wrench. Then its just a matter of buying a clutch kit (plus CV gaskets), dropping the motor/trans assembly, splitting the motor/trans. Tom in parts (1-888-280-7799) can get you everything you need, but if you have never done this before, you should seek the assistance of somebody experienced in turning wrenches. Its not real difficult, but it will require allot of nut and bolt turning. Please feel free to contact me if you need further assistance; I can offer you more details when your ready..

You really didn't need to pull the motor to do it. If you are considering new chains, you might also carefully inspect/replace the gears and of course upgrade to the new guide rails. I'm not sure what to tell you about the cam shaft: cams are always a trade off and there was a good reason why Porsche used the ones they did. You might get a little from a new cam, but it wont be enough to get excited about. For real power in your car you'll need to up the compression and open the intake ports. Same really goes for the flywheel. You might get your flywheel lightened by a machine shop, and use a "S" aluminum pressure plate. Your car will rev a little quicker (hardly noticeable) but it will be more difficult to drive around town. Now is the time to do any clutch work though, (and perhaps a valve job). Most 911s like Sport Mufflers, but they can be noisy. I wouldn't do it to an old muffler unless it was in very good condition. james > If you are interested in ordering a kit, please give Tom in sales a call at > 1-888-280-7799, and he can help you out. > > Mtcorwin@aol.com wrote: > > > I just took out my engine from my 1971 911T.

Glenn Subject: Re: 1983 porsche 944 > Hi Franklin, there is nothing special about that part of the A/C system. Any qualified A/C technician should be able to service it. If your A/C seems to be working OK, I don't know that I would mess with it too much. I forget the name at the moment, but the thingie with the sight glass is a filter (of sorts), it may be defective, (common replacement item). To replace it will require evac and recharge of the entire system; not cheap. There is a very lengthy factory technical bulletin concerning A/C and retrofit to 134a. You may want to talk to a local shop that specializes in A/C only. I don't to too much A/C work these, but if you need more answers, I get them. Good luck james > > "Franklin A.
