berty987

I suspect the sensors are already fitted for oil pressure and battery voltage as the 987 has indicator warning lights if either fall below a set value. The question is whether the wiring loom to the existing 987 cluster is a CAN based loom or multi strand. I seem to recall there being some discussion its a CAN based system and the cluster is linked to the rear DME ( ECU) so that clocking the car is not possible by swapping the cluster. I suspect you would need the official PWS tool to re learn a new cluster to the original DME and then configure the cluster as a 911 part, thus activating the additional inputs on the CANBUS so the additional gauges were activated. I know the 987 and 997 share the same rear DME this allowed me to retrofit the PSE to my 2005 987 using the signal from the 997 PSE code in the PWS to activate the DME output. As I recall you connect the PWIS to the ECU then tell the PWIS it is a 997 rather than a 987 and use the 997 options menu to activate the additional functions you require. If the 987 and 997 use the same canbus architecture ( ie all the signals are there ) you may be able to simply add the 997 clocks, but I think it still needs coding to the rear DME

I have a 987 3.2 which is a pre production model with a few prototyp labels, so it has a few anomalies in terms of parts fitted , so far I have discovered a different AOS and the rear ARB which differ to the standard PET parts list and the ECU seems to have a different AFR setting. I am about to overhaul the rear suspension and again have a few part numbers which don't seem to match the PET listings. Though I˙m sure I can fit standard parts , if they are different or unique I would like to keep the originality. Rear Coffin arms are 996 341 341 08 - I think this is a standard part same used on the 986 and 996 Track control arms are 997 331 245 03 and 996 331 245 10 - Parts listing seems to suggest 045 in the last 3 digit series ( one side may have been replaced ) Long Fork Arm 987 331 143 02 - Again an unusual part number, generally its listed as 043 in the last 3 digit series Any help much appreciated.

I took a vernier to a cayman r pse and boxster spyder pse , the tube that connects the rear muffler to the manifold are different sizes 47 and 55. the bigger diameter gives a deeper note.

Unfortunately you wont be able to fit the base model cluster either as the speed range is different and i suspect the clocks are calibrated to the model based on the pick up from the gearbox / wheel hub and gearing used. You could try contacting reap automotive in the uk , they have been changing clock faces on porsches for many years.

For power increases on a 3.2 987 there are some cost effective options which give real gains. First up is to replace the 68mm throttle body and split intake plenum with the larger 76mm unit from the later 3.4 boxster/ cayman engine , used parts will set you back around 200 plus a set of silicone reducers to make it fit, for another 50 odd pounds. Adds around 8-10 hp. Next step would be to have an ecu remap for around another 400 pounds and will give about 10 hp. After that you are into exhausts and manifolds which are pricey , starting at 600 for manifolds or rear systems on a budget going upwards to 4000 for a complete system from someone like milltek. Expect another 5-8 hp peak from these mods. Forget air filters they are not required on the 987 as its already well over specced.

The Bose system consists of an amplifier plus additional speakers. The PCM / CDR must be coded to use the MOST system to communicate with the amplifier. The Bose amp will also have its own power as well as the speaker output loom which goes to the door, dash and rear speakers in the sub woofer box. You wont find a TSB on retro fitting BOSE because porsche didnt offer it as an aftermarket option. Ideally you need the wiring diagram and the workshop guide for replacing individual components.

Interesting project but I think you need more than the motor and a set of new clocks. The 987 S uses either a 3.2 or 3.4 engine depending on the model year (3.2 up to 2006 and 3.4 after), the 3.4 is an M97 engine which uses variocam plus so there will be more to the wiring loom and control in the rear DME. The 3.2 engine will aslo use a different engine map to the 2.7 so the DME must be changed or at least modified with the correct fuelling and ignition control. Then there comes the issue of the main gateway being coded for a 2.7 but the DME being a 3.2 or 3.4, I.m not sure how the engine swap gurus overcome this mismatch. The S clocks are ranged differently to the 2.7 model due to the different gearing and final drive ratio , are you planning to fit the S transmission as well as the motor to overcome this ?

The 3.2 engine is an M96 and uses a single row 20mm bore 47mm outer diameter by 14mm thick 6204 bearing, the later cars use a larger bearing. An LN engineering upgrade is available that replaces the standard bearing with a ceramic hybrid unit and can be done with hte engine in place without the need for a full strip down. Its still a costly exercise as the gearbox , clutch and flywheel need to be removed to gain access.

Will be interesting to see if Porsche either release the rights for navteq to sell update discs or launch a new update themselves. The mapping data on the 2008 disc is actually 2007 ! That makes it 5 years out of date ...............At the moment the only choice is to buy a map DVD from Porsche.

Are you able to eject the CD you put in the PCM to do the upgrade ? The PCM has a software reset by pressing 148 on the keypad. Alternatively you can pull the fuse that powers the PCM in the fuse box and leave it out for a few minutes. The PCM update should be done only when you are sure you know what procedure is required. This means you need to interrogate the PCM first to find its current software level and what other devices software levels are on the system. Depending on the date of manufacture and options fitted , sometimes a Bose update is required or in a few cases a complete replacement of the bose amp to a newer model.

The 987 3.2 had a motorsport AOS developed for it ( I have the prototype fitted to my car !) , but it was never offered as an official option. The actual option code identified but never listed was 661 Verschaerftes abgasconzept ( roughtly translated - stricter emissions concept) . Whether it was ever actually intended for motorsport we will never know , but its similarity in design to the 996 motorsports AOS suggests it shares much of the same capability. The part number for the AOS and associated hoses only exists in the main dealer "special parts" catalogue. Unlike the 996 motorsport AOS , the 987 part has provision for the secondary air pump found on the boxster and design of the 987 engine layout (reversed to the 997 / 996). With the 987 3.2 engine being essentially unchanged from the 986 (ie its still an M96 variant and uses the same throttle body and inlet manifold , heads / valves etc) I suggest the motorsport AOS will actually fit both the 986 and 987 cars. The price is somewhat prohibitive at nearly double the 996 motorsport part. Here in the UK the part is listed at close to a thousand pounds ! Details of the part can be found on planet-9.com here : http://www.planet-9....stallation.html Here is the thread which shows the subtle differences between the boxster and 911 "motorsport" part and original part: http://www.planet-9.com/cayman-boxster-modifications/25166-oil-separator-modification-pics-aos-motorsport-vos.html Others on the planet-9 forum have experimented with cutting and modifying the 996 part to look like the 987 original. Not sure if the 987 part would be allowed in motorsports race series , but suggest its more likely than a 996 part as its developed for the car as a specific part (even has a 987 part number !). What other "hidden" developed parts for the 987 or any other model exist we can only guess. Every now and then I'm sure another gem will come to light.

mwswenson is correct. The 987 uses a diversity antennae on the pcm or singular antennae from the windscreen on the standard stereo. The connection under the windscreen cowl is I beleive for the PCM/ navigation antennae . The connection for the radio antennae is under the passenger footwell cowl.

You dont need to update the PCM software , only the Navigation software. This is done as part of loading the navigation DVD . The only time a separate disc is required is when the PCM or navigation software is pre level C ie the map DVD originally is 2006 or earlier.

I beleive the I tunes format is different to that of standard MP3 , this may be the cause of your problem. Have you tried using MP3 files that are not from I tunes ?

Hi Volker. First you need to remove the headlamp from the front of the car. There is a metal tool for doing this in the tool kit in the front luggage trunk behind the cover where the warning triangle is located. To remove the headlight you need to open the front hood and remove the rubber bung in the bulkhead next to each headlight. Insert the tool and rotate by 90 degrees and the headlight will become free to remove. Take the headlight out and remove the 4 screws on the rear cover. Looking inside the headlight you will see a small metal tag on the rear of the headlamp reflector, next to the tag are two stamped letters O and T. O is set for the country of origin (in this case RHD ) T is for touring (IE LHD). You need to move the lever/ tag on both headlights to the T setting.
