This likely needs some testing but give it a try (if you want). Door Panel Removal/Install Instructions

Is it the lead that plugs into the relay sockets?

Yes you can likely get it in Savanna. But, as Gert said we need to know the type of seats (sport, comfort, or standard). p.s. We know your car is a MY99 Cab ;)

Note: - The following values relate to the empty weight, i.e. full fuel tank, vehicle with spare wheel/collapsible wheel and tools, but without driver and without additional weights. - X74 = 30 mm lower. This can be identified by 1 yellow mark on the shock absorber.

If required in a customer service matter, a caster adjuster may be installed (Serv. No. 40 19 23/Installing caster eccentrics). - The toe-difference angle value is also influenced by the vehicle height! For this reason the measured result must be evaluated accordingly! No action is necessary in the case of small deviations from the toe-difference angle required value, as long as the value to the right and the left is almost the same.

Joel Reiser just answered this question at the PCA website. (BTW... 986 and 996 use the same coolant). Here is what he had to say about coolant:

The front bumper removal and installation is covered in my DIY for the 3rd Radiator Install. This should have everything they need. Be sure and get some before and after pics! :jump:

Chad, Here is a link to a large (2.5 MB) PDF file for steering wheel removal and OBC hack. You may not need the OBC hack but the steering info is good. Steering Wheel and OBC Hack

The tank is on the right (passenger) side of the car. My understanding is you would need to drain the oil from the bottom of each turbo and that it is an 8 mm hex bolt. Sorry, I do not have a picture or diagram. I'm trying to arrange to take pics with a local guy on his TT oil change. BYW... even after draining all three there is still 4 liters of oil in the engine.

IMHO Yes. Here is why I think so... The X51 beefs up the engine, oil system and cooling. Here is a short list: - new intake manifold with modified cross-section (material: sand cast aluminium ); - new intake pipe supports adapted to the form of the intake manifold; - new exhaust manifolds with larger cross-section and optimized flow behavior; - new cylinder heads with optimized, CNC-milled inlet ducts; - new camshafts with larger valve stroke on the inlet side and modified inlet and outlet timing; - inlet valve springs adapted to the enlarged valve stroke; - modified partition box in the oil pan; - modified maps for the DME control module. - new underside panel in the transmission area; - additional radiator in connection with modified front spoiler, except on the 911 Carrera 4S (996). or you could always go with the new GT3 where you get the base for the R and RS racer cars... or better yet a cup car ;) wait I guess that is not streetable... darn :rolleyes:

JayM, I sent you (via email) a link to a draft of TT oil change instructions. Have a look and tell me where it can be improved. Thanks! :beer:

Ben, 3.4 liter or 3.6 liter? Option on a new car? or add on to existing car? :huh:

Jonathan, Here is an online source I found. Not the least expensive but they do have stock and free shipping. 1st Optima Battery Sales

Jonathan, If you look at his pictures... the original (Porsche) battery has the positive terminal on the passenger side of the car closest to the windshield. When the guy in the article mounted the Optima Red Top battery the positive post was still on the passenger side but to the trunk side. So, my point is that if you got the Orange Top Reverse Post battery the posts would be in the original postion (passenger side - closest to the windshield)... perhaps allowing you to use the existing cable. Or maybe it is still too short... we won't know till we try ;) BTW... I agree with the centering of the battery on the plate.

Well, there is are two TSBs for this so your dealer may still do it for free. Certainly worth asking about. If you want the TSBs with the part numbers and instructions, email me or join the forum so I can email you. Thanks and welcome to RennTech!

Specs on the 34R Reverse Post Orange Top (identical to the 34/78 Red Top): Volts: 12 Amp Hours: 55 CCA @ 0° F: 750 CCA @ 32° F: 980 J240 Life Cycle: 10-12,000 Deep Cycles: ~50 Reserve Minutes: 104 Physical Size L" x W" x H": 10 x 6.8 x 7.8 Weight Lbs.: 38.8

Ok, your oil change page is ready for testing... Gt3/TT/GT2 Oil Change page I am not sure on the engine drain plug part number -- please verify with your dealer (and let me know). Also, let me know the wrench sizes if you can...

I think the one to try would be the Optima Model 34R Orange Top Reverse Post Battery (same specs as the 34/78 used in the article). It seems like it might solve the cable issue since the posts are on the correct side. You would still need to make a mounting plate though.

Ok. I don't know if this is true or not, but I was told (by a paint guy) that "L" stands for laquer, or an "A" would stand for acrylic. He went on to say that Porsche does not use anything but laquer.

On pre MY02 cars they used a separate color code for water based paint vs. conventional paint. For Ocean Blue Metallic -- 3AZ is water based paint and 3AY is conventional paint.

The OEM clutches are good. I don't see any reason to go with a sport type clutch unless you are changing the flywheel too. The dual mass flywheels on these cars make them very "driveable". A lighter single mass flywheel and HD clutch will make the car need a lot of revs to get off the line -- kinda like a race car. Porsche introduced a new clutch pressure plate in MY02. The driven plate has also changed (from 996 116 013 05 to 996 116 013 06). I don't have details on why or when but they changed the (MY02) pressure plate. But... the part number (for MY02 and newer) has changed from 996 116 027 05 to 996 116 027 06. So I would make sure your dealer does not use old stock -- get the newer pressure plate (996 116 027 06) and the newer driven plate (996 116 013 06). p.s. THANKS! Glad to have you here

According to the Porsche Tech Manual... Yes, they can be machined. Here are the specs (Carrera only, GT3 specs are different): Brake disc thickness, new -- front 28 mm, rear 24 mm Minimum brake disc thickness after machining* -- front 26.6 mm, rear 22.6 mm (* The brake disc must only be reworked symmetrically, i.e. from both sides evenly.) Brake disc wear limit -- front 26.0 mm, rear 22.0 mm Peak-to-valley surface roughness of the brake disc after machining, max. -- 0.006 mm Thickness tolerance of the brake discs, max. -- 0.02 mm Lateral runout of the brake disc, max. -- 0.03 mm Lateral runout of the wheel hub, max. -- 0.03 mm Lateral runout of the brake disc when installed, max. -- 0.06 mm

The Optima battery is a good one IMHO. Lighter and gel filled. I have seen them in Costco here for $99 (USD). Now the bad news -- it only comes in one size -- which means you will need to make a mounting plate to secure the battery in your car. I am attaching below a PDF from a guy that wrote up his experience in the San Diego Region PCA newsletter. He made a mounting plate and changed the cable (as the old one was too short). I wonder if the longer cable would be needed if the mounting plate were made to more center the Optima in the original battery position? --- Ah, another project I haven't gotten to yet...
