berty987

Personally I'd stick with Bridgestone or Michelin , The N rating means they are designed specifically for Porsche cars and in conjunction with Porsche , so they should be the optimum for your vehicle.

I think they're the lightweight magnesium wheels and cost about 1000 pounds a wheel. Here is a pic of a set on ebay for sale (unfortunatley from a 997 and in the UK)

Sidelight and foglight connections may also need changing over to Cayman items. If you are looking for someting different , try this from Ingo Noak in Germany .

Why are you considering changing to a wider tyre ? I doubt you will get better grip, more likely worse grip in the wet. It may also be difficult to get the correct N rated porsche approved tyres in this size.

Don't forget the 997 and 987 are basically the same car when it comes to the center console and doors , only the dash top is different. your other alternative may be to find a breakers yard that has a 987 or Cayman. May be worth extending the e bay search to worldwide, it may still work out cheaper even with the postage.

You could try e bay. A lot of this stuff is actually made in China and the far East, often the suppliers try to sell it direct on e bay.

I picked the car up last night from the workshop and spoke to one of the people in charge while reviewing the parts. Really strange , the clutch friction disc still has plenty of material on it , the pad sections still clearly visible on both faces and no signs of bad scoring , just one small piece missing (about the size of a jean rivet , but only about 1mm deep and friction material still underneath). The pressure plate is also in good nick , no broken fingers and only discoloured where the friction material sits on its surface not blued or straw colour suggesting its got excessively hot. The fingers of the lutch cover are blue in colour but not sure if this is how they look after treatment or if they have become hot. The DMF is the same story, no surface damage , just slightly discoloured wher the friction surface sat against it. I tried the twist test and the two halves of the DMF do move about 20-25 mm with little effort , then it just locks up and you can definitely feel very strong resistance. The movement appears to be free travel though, as the rotation isnt self returning over the first 25 mm. The clutch pedal doesn't seem to have a biting point any lower than before either , so i'm still confused why the clutch was slipping when you pulled away with some urgency. This was the only time i felt the clutch slip and it was severe (3-4k revs and in gear with no movement , just piles of acrid smoke from the engine vents and under the car !). If it had happened only once , then i could understand the clutch may have been hot already , or prerhaps glazed. I havent tried any grand prix starts since getting the car back and the mechanic tells me there is no adjustment in the clutch so the biting point must be normal , but it feels about half way on pedal travel.

The seller has an 02 996 , michael has an 03 Are you suggesting the PCM in the 996 was originally a PCM 1 and changed on model year 2003 to PCM 2 ? If not , then i'd argue these disks may well work. The part number listed is for one of the Cd's for great britain and not the whole set .The part number is applicable from chassis number 991S6 03524 to 991S6 42489. If the car that Michael has falls between the two chassis numbers then it should work on the system. Take a look at this thread, i think it answers all your questions and may well give you the opportunity to use a cheaper map source : http://www.renntech.org/forums/index.php?showtopic=13578 There is also an upgrade disk available for the PCM2 to take it to version 3. Around 2001 DX coded maps started to become available for most nav systems , these allowed for additional info such as TMC to operate. This may well be the difference between PCM1 and 2 regarding the map type , so a DX coded vauxhall /opel Cd may well do the trick. Best to talk with one of the suggested suppliers before spending out.

Michael. Advertised on E Bay at the moment are nav disks for a 996 look here http://cgi.ebay.co.uk/Porsche-911-996-PCM-...1QQcmdZViewItem Item number: 200100984090 Part Number: 996 642 133 06. Contact the seller ref details. If you need help with an upgrade i have the version 3 software for the PCM 2 purchased in error.

The current generation PCM 2.1 has only just started to include parts of Europe such as Greece , so you will probably need a MAP update from late 2005 if not early 2006. Navteq and Teleatlas (Navshop.com) have the OEM map market sewn up , so one or other will supply Porsche the map disks. I remember reading of a guy that could mod the PCM 1 to allow a GM/ Vauxhall Navteq disk to be read on the Porsche unit. I think the company was satnavsystems.co.uk. If you have the PCM 2.1 with the external DVD unit then there is a software update that will allow you to use the map DVD's produced after 2004 on your PCM. I've no experience with the PCM 2 so dont know if its any different to the PCM2.1 other than the front panel.

The indie that have the car seem pretty thorough and seem to know their stuff. I've decided to get the DMF replaced and follow their reccomendation, the part is minimal in cost compared to having the whole transmission out again in a year or so if the DMF fails. Luckilly no signs of the dreaded RMS leak and they have advised if it aint broke dont fix it, so although an unexpected additional cost , its still cheaper than OPC prices and i have peace of mind. to be honest when i bought the clutch I did consider going the uprated route with lightweight flywheel, but decided against as I want to use the car for touring and road use rather than sprints and track. Since VW/ Porsche have their hands in each other's pockets I'm not surprised that the transmissions are similar if not the same on the 2.5/2.7 and Passat/ A4 . Certainly porsche seem to list a lot of special VW tools for maintenance tasks. Regarding Oil on the Vw , I've been using synth Castrol GTX magnatec since I heard of the sludge problems caused by non synth oils on the turbo engines. Like you the Vw is now old enough to get my full attention and I do what i can on the car myself. With its current mileage the top of the engine is a little tappety but I'll probaly have the cam covers off to inspect if it gets any worse. I'd love to tinker on the Porsche but the stakes are higher if something goes wrong and people like to see official reciepts for work when you sell it on. So money on the table and wait for the call its all fixed ready for collection , then off to enjoy "the best summer ever" we are promised this year !!.

Thanks for the responses .. Mine is an '05 987 S ... saw a post that referred to an '04 987 ... sounds like your salesman was right .. although, even if released in '04, I would have thought they would have titled as an '05 Yes they are called 987 models and designated 2005 model year , though actually manufactured in 2004. Thats what I have.

Spooky world that you have a '99 passat with 115,000 miles as a second car.....so do i , with the same mileage and on original clutch too. I wouldn't take the car to porsche because of the warranty clause on wearing items and also if unsuccesful in the claim it would be a crippling 2000 pounds for the work (this is costing just under 900 including the DMF and clutch ). I spoke with tech support at LUK (DMF suppliers/ mfrs) and they quoted there is no specific tolerance for the amount of movement between the two parts of the flywheel. Though the TSB suggests 15mm is allowable LUK suggest that up to 30mm is common depending on the application to which the DMF is fitted. It will be hard to prove the car has not been abused , since clutch slip at 26,000 miles is very unusual , and i purchased the car with 20k on the clock , so i have racked up some fair mileage. What is interesting is the guy at LUK said that the two parts of the DMF are separate and there is a friction section sandwiched in between. This is sacraficial in the event of an excess load being placed on the gearbox or engine and can itself cause clutch slip symptoms if damaged. The DMF can also only be truly tested if it is seen in a dynamic state , so the bench test is somewhat limited. Are you suggesting in your post that the Passat DMF and Porsche item are actually the same device ? There seem to be very different capabilities and horsepower requirements between the two engines.

I think my car was the 16th boxster 987 S built and was pre registered by porsche in stuttgart with the prestigious S GO 1000 index. Originally registered in September 2004 i imported it myself about a year ago after purchasing from porsche after they de fleeted it.

Calling toolpants or any service techies out there. I have a 2005 model boxster (3.2 s)currently in with an indie for clutch replacement. The car has covered 26,000 miles and symptoms were high biting point and clutch slip when pulling away from standstill when driving enthusiastically. The indie has taken the clutch apart and advised that the dual mass flywheel needs replacing !!! The clutch doesnt seem to be worn out , and there is no scorring on the flywheel , so they put the slip down to a weak pressure plate and the flywheel. They are suggesting the flywheel needs replacement becuse the tolerance is out on the amount of slack between the two plates. anyone know anything about testing the dual mass flywheel (same as 986 boxster) or what the tolerances are ? Is it normal to replace the flywheel with a clutch or are they being over cautious ? Need to confirm tomorrow so any replies welcome. thanks

Sounds a pretty comprehensive device , though most of the options i already have , and the number of times I feel i'd need or use the stationary "one touch" may be limited. If you own or are buying a 987 without PCM / electric seats I can see the attraction and it looks simple to install. Question is how much ?

This subject along with K and N filters seems to emerge time again on these forums. There is no benefit to adding more air , unless there is fuel to combine with it and the ignition timing altered to compensate. The only time you need mod the air box or filter is if you have an ECU remap to take advantage of it. Adding too much air makes the fuel mix run weak and overheat the engine causing damage both short and long term. The dyno figures don't mimic the car moving through air , where there is a forced induction process taking place. On the DYNO the ECU overfuells by its allowable tolerance , giving a very marginal gain for the additional air being drawn in. On the road , in real life you actually get too much air as the baffle isn't there to limit the ram air effect , resulting in a weak mixture and the engine running hot . This is particularly evident after extened speed and high rpm runs. An overhot engine means the oil doesn't do its job properly and things can start to warp or crack. You're wasting your money and taking a risk , fitting a performance air filter or worse still removing the baffle without an ECU remap. The CAYMAN uses the same air box and filter to supply a 3.4 L engine producing another 15 bhp , the differences between engines are in the intake manifold / throttle body, not the airbox part of the induction system. The 9ff modified boxster 3.2 uses a modified inlet manifold , air filter , cams , exhaust headers and ECU to produce close on 340 HP. The ECU remap with performance air filter alone gives close to 300 HP , suggesting the baffle isn't really doing much to restrict power.

I have a LHD boxster with this mirror tilt function , and as I found out , it requires additional wires in the mirror loom to function properly. On my 987 I have the electric memory seats with mirror position memory. If you don't have the extra wires in the mirror then i'm not sure the mirror can return to the original setting after the reverse gear is de selected and you start to drive forward. Also im not sure how you would set the lower position of the mirror since it has no memory. If you are only getting the relay mod for the dipping mirror function for a 987 I'd look a little deeper into what its actually going to give you for your $$$. The OEM unit gives you a memorised position for the reverse function, and it can be turned on or off as a function by the position of the mirror knob in the car. It also resets the mirror to the original drivers position after you get above 5mph in forward gear , or you move the mirror knob to a different setting. If this aftermarket kit can do some of this functionality then it sounds a good investment and it will save kerbing those nice alloys particularly as the 987 feels much wider track at the rear compared to the front.

Strangely they released this hard top for the 986 first ! Not cheap and made of carbon fibre rather than aluminium like the OEM hardtop. Looks good ,but a bit of a pain to keep removing the boot lid when you want to fit it.

I had the same issue. You will need to update the software in the PCM to be able to use any map DVD later than 10.2004 release date. try porsche to see if they will do it for you , but usuallly they insist you buy the update DVD with the software as a pack from them. Its not cheap ..in the UK it costs the equivalent of 800 USD.

Bridgestone also offer N rated tyres for the Porsche as well as Michelin and Pirelli. The N rating is an additional spec reccommended by porsche for fittment to their cars. I have michelins on my 987, and a 997 targa i drove recently had the bridgestone items. Have to say considering the additional tyre width on the 997 the bridgestones did seem a very quiet tyre.

Thanks for the info. I talked to the people at Thatcham today and they told me that the tilt sensor and battery backed up siren was developed by porsche in conjunction with them to suit the Uk market and insurance companies. Apparently the I536 option which is only standard on UK RHD cars includes not only the tilt sensor, bracket and Battery backed up siren , but also a shaering lock nut for the ECU. Apparently a security feature addition required by Thatcham to get approval status. I have managed to find another UK 987 which has the alarm and now know the wiring colours , so hopefully a bit of additional digging will confirm if these wires are in the loom and just not terminated with a plug. The siren is just a two wire device so hopefully it can't be too difficult to retro fit. Ideally I need someone with access to the Porsche technology database to dig out the UK wiring diagram for me....Loren can you help on this ? Thanks

Thanks toolpants. The siren and tilt sensor can be purchased over here without issue, its the wiring side of things that concerns me. I beleive the 997 and 987 have a different alarm system to the 986/996 is this correct ? do you know what the wiring loom for the upgrade consisted of or have apart number ? Certainly the tilt sensor looks like the same as I have seen in the parts catalogue for the 987 , but the alarm battery backed up siren is definitely different to the Uk ones. Also i am told the tilt sensor is fitted under the drivers seat in the Uk. I will continue to Press porsche for some answers and let you know the outcome. In the meantime if you have the part numbers or any more pics , please let me know. Many thanks again

I have a European spec 987 s , it is fitted with the factory security system including immobiliser, separate horn and interior sensing with luggage comparments. In the Uk I am told all UK spec cars are fitted with an additional battery backed up siren and tilt sensor. The part code for this additional equipment is I536 and consists of siren 955 618 237 01 and tilt sensor 997 618 265 00. There is no mention in the parts list of it being specific for Uk vehicle ie only available RHD or with option IC61 (uk) so i am assuming that all porsche 987's carry the same wiring loom to allow retro fittment. I contacted Porsche Uk but there seems to be some disagreement between porsche Uk and local dealers as to whether the wiring is in existance and also if it can be retro fitted. Any technical people out there that can shed some light on this? Also it would help if i knew where the tilt sensor and battery backed up siren were supposed to be fitted , so i can check for plugs myself. Thanks

Though there is no alternative map that will run on the porsche PCM2.1 than porsche's own brand , the maps are supplied and manufactured by Navteq. Typically navteq update the mapping data twice a year (in europe) so there is usually a new map DVD available. This will have updated maps but probably no more levels of POI. They are expensive too, in europe the MAP dvd updates cost about 500 euros (700 USD). The update DVD is usually supplied with a firmware update disk that allows the earlier 2004 model PCM2.1's to run the later map disk and may enhance the features and detail on later PCM 2.1 units. normally the supplying dealer perform the updateof firmware free , when you buy the map update.
