Mods & Updates

Buying a 993 can be very rewarding, and give you a very cheap to own car – with next to zero running costs. However, we all like to tinker a little bit don’t we?
The thing is, on a 993 – these things tend to become very slippery slopes!

This is what I have in the pipeline at the moment:

  1. Further re-trimming to ‘de-green’ more of the interior
  2. Live re-map @ ChipWizards
…..and these are the bits I’ve already done:

July 2017

Today I took delivery of the new front indicator lenses in the original Amber. This is the correct lens colour for the car, and matches the amber side repeaters and amber rear indicators.
It became popular some years ago to fit clear lenses with orange bulbs on some cars, and a previous owner had replaced the front items on this car. I replaced the side repeaters when the car was having the re-spray earlier this year – but this just made the clear indicators look wrong.

Here is a ‘before & after’ shot…..


May 2017

Stickers:
Following the re-spray, all the factory stickers needed to be re-applied. These were ordered from Porsche and arrived after a long wait!
Tyre Pressures sticker: 993.701.287.30 (Silver)
Engine Oil sticker: 964.006.111.00 (Silver)
E13 Sticker: 993.701.189.09 (48 R- 014003)
E4 Sticker: 993.701.189.10 (64 R-00 93003)
VIN Sticker: 993.701.102.13


April 2017

The engine ‘Tidy Strip’ – or “Motorraumdämmmattenleiste” to give it its real name!
This fixes at the top of the engine bay to suspend the, often sagging, insulation. You can see the results plainly – a quick, cheap and easy fix.


March 2017

The car failed its MOT because of the disks. I knew these were borderline as they were advisories on the previous 2 MOT’s….
There was no point just putting some disks on, so I went for all new Brembo Disks, Pads, Vibration Shims & Pad-Wear Sensors.
While I was doing those, it made sense to replace the 2 front tyres with a new pair of Continental Sport Contact N2’s – right?
And while the tyres were off, I got the wheels re-furbished at ‘Rhino Wheels’ to go back to the factory look: Sand blast, acid etch, powder coat and finally Lacquer – finished off with a full new set of ‘Black on Silver’ Porsche crested centres.
With the wheels back on I had the new steering wheel fitted and aligned, and a full 4 wheel Geo set-up done at Ninemeister.

Finished 05


February 2017

While the car was having all the work done at Ninemeister, I decided to go for the rear wiper delete modification. It was an expensive choice, as a new rear screen was nearly £500, but if I was going to have this done at any time – it made perfect sense to have it done whilst the glass was out due to the re-spray.
I’m glad I did this – you can see from these pictures that the back end looks so much neater without that wiper arm, and the removed items (motor & arm etc.) are in the box of spares if it ever needed to back to standard.


July 2016

I sourced another spare steering wheel – but this time a 3 spoke ‘manual’ 996 type, with the intention of fitting some Mercedes AMG C63 ‘paddle shifters’
After fitting the paddles, I sent the steering wheel off to Jack at ‘Royal Steering Wheels’ to get re-trimmed. I asked for smooth black Nappa leather, slightly thicker and dark green stitching.
The results are very good……..

And fitted……


July 2016

Some more essential spares ordered, as I seem to have lost these during the times in the garages – spare DME relay (don’t leave home without one of these!), Mobil 1 Oil bag and litre of oil.


June 2016

I have decided to get new screens fitted, so sent the car to Ninemeister in Warrington.
The front screen was annoying me. Although it was OK, it was 20 years old, and very pitted – so was awful to see through in heavy rain even with new wiper blades.
Of course – this means taking the glass out, so we may as well address the tiny rust blisters around the scuttle….. and this in turn means I need to get this area re-painted.
And if I’m re-painting this area, it makes sense to do the full car – right?

Check the ‘Restoration’ pages for full details.


April 2016

Leathercare Renovations in Warrington for full interior refurbishment
I also decided to re-colour parts. Note how the dash top, door caps and top of rear shelf are all now black? This really breaks the colours up nicely, and also removes a lot of glare on the screen from the old shiny green dash.


November 2015

The Cat Bypass modification & cam covers:

This is essentially a 1.5″ stainless tube welded between the input and exit tubes to the catalytic converter, and is fully reversible if I get fed up with the extra noise….

While these back boxes were off, it made sense to look at the chassis legs to check for corrosion around the mounting plates, and also replace the cam-cover gaskets as there was a small oil leak.

Once the rear PU and back boxes were off, we could take a good look at the chassis leg mounting brackets. They were all in good order and the bumper supports had also already been replaced some years ago. Heat Shields and mountings looking good, checked the chassis legs on both sides – all good, so just coated in Dinotrol before re-assembly. Back boxes modified……

….and this is what it sounds like: {sound-file}


August 2015

Someone took a photo of the car recently as it was braking in to a corner. How embarrassing – two of the bulbs on the high level brake light were out!
So – rather than getting the soldering iron out and just replacing the bulbs, I ordered the LED replacement kit from ToreB in Oslo.


July 2015

I decided to go with the RS style rear wing, so bought one from Germany. Of course, as I’ve decided to keep my standard 993 engine lid for the ‘box of bits’, I needed a new grille for the RS wing so bought one from OPC Bolton along with new seals, striker plate and all fixings. Now it’s fitted, I much prefer the look of this wing to the original ‘Aerokit’ wing. I now have a choice of 3 different looks, and just an hours’ work to swap over!


May 2015

To complete the front end, I ordered a set of the ‘Turbo S’ ducts. These replace the one piece light at the front which contains both the side light and the fog light. Unfortunately, the standard light fitted to these just has the side light – you end up losing the fog light. I hate switches that don’t do anything, so I need to do something similar to the second image to add the second bulb.
I’ll get these painted when the car goes in for it’s respray, and then fit them when I figure out how to include these fog lights.


April 2015

My car came from the factory with additional option code X62 Aero-Kit 2 rear spoiler [993.512.980.00] – but this had been removed before I bought the car.
As I wanted to have the original car, I sourced the spoiler from a Porsche club member and bought it for my box of bits.
…..not sure I will ever fit this – I just wanted to have the original parts.


April 2015

The rear wiper arm is a very complex movement on the 993, and as such is susceptible to snapping if it isn’t moved carefully. A lot of cars have repaired items, where a strip of aluminium is riveted to the arm to put it back together. Although this is OK, it can mean that the wiper rubber doesn’t always keep 100% contact with the rear screen. Mine was like this, so I decided to just replace it with a brand new part:

Rear Wiper


April 2015

Air Conditioning. Although it was blowing cold, I didn’t think it was anything like as cold as our VW Golf, so took it over to ‘Chill-Out’ near Southport for a check over. Jim at Chill Out is a fellow Porsche enthusiast, and has a 993 himself.
We did a full evacuation of the system, pressure tested and then re-gassed. The good news was that there was still plenty of gas in the system – so no leaks. The fact that it isn’t as cold as the Golf is just because that is a one year old system, and the 993 is a 20 year old system.

January 2015

I’d noticed some instability when going round some roundabouts if I’m pressing on a little, and also on some faster left hand bends in the wet. After a couple of half spins, I took the car in to a tyre specialist for a check over, and to get all 4 wheels balanced.

One week later and I still wasn’t happy with the handling, so I went to see Kev at Classic car Workshop. With the car on the ramp and the back jacked up, we could see movement on the passenger side wheel at the back. Look at this tyre. Fully inflated you couldn’t see the split, but once it was off….

Tyre

I have no idea how the guys at the tyre place missed this when they balanced the wheels last week!
I had a new pair of Continental Sport Contact 2’s fitted – good as new now and can really give it the beans round some of the bends!


January 2015

I noticed that the car is slow to turn over if it is left for anything more than a week, and I have no idea how old the Japanese battery is, that was fitted – so I ordered a new Bosch S5 battery and fitted that.


December 2014

I submitted a request to Porsche to check for outstanding re-calls. None found: Recall Check


July 2014

I decided to replace the original 4 spoke steering wheel with a 3 spoke model from the 996. This wheel is a little thicker to grip, and does look more modern without looking out of place. I’ll retain the original wheel with my box of bits

Step 1: Disable the power to the air-bag at the battery. Disconnect the negative terminal on your battery and let it sit for at least 15 minutes if you are brave, 30 minutes if you are normal, and about an hour if you are paranoid. Also, make sure you have your radio code handy before you disconnect your battery too. You’ll have to enter it when you are done.
Step 2: Remove old 993 wheel and horn connections. NOTE: The bolts in the 993 Four spoke steering wheel are #27 Torx and those in the 996 are #30 Torx. The Airbag electrical connection pulls straight out from the back of the bag.
Step 3: Remove the nut on the centre bolt with a 24 mm socket
Step 4: The wheel just pulls straight off….gently rocking it from side to side.
Step 5: Install new 996 wheel and align hub.


April 2014

Applied to the DVLA for a V888 query. This provides all details held by DVLA for the history of the car – 32 pages of data came back!
Photocopies of all V5’s since new and printed list of all owners and plate changes.


March 2014

I replaced a couple of other parts that were either missing or showing signs of wear and tear:

1. New PIAA wiper blades
2. I found an original Porsche Mobil 1 oil bag, complete with gloves and wipes:
3. More (essential) little bits fitted:
a) Mirror plugs
b) Wiper Buffer
c) Door lock caps
4. A couple of my over-mat retaining brackets were broken, so I decided to replace them all. The mats now stay in place nicely:
5. Whilst giving the car a thorough valet, I removed the number plate at the front and noticed that the mounting bracket was cracked. New one ordered and delivered……


February 2014

I’d noticed a bit of a ‘squeal’ on cold mornings, so decided to get back to Kevin at the Classic Car workshop for a closer look. As suspected, the ‘V-Belts’ were a little loose, so I decided to change them all. The old ones were still serviceable, so saved them with the spare wheel in case of emergencies.


January 2014

A strange quirk with the ‘993 is that when you use the rear wiper, there will be 3 wipes. What’s that all about? Why does it need to wipe 3 times?

Fortunately, there’s a quick modification…….
Remove the rear parcel shelf and you can see the rear wiper motor. The relay that controls the motor is also there. Simply remove this and replace with a VW/Audi type 53 relay (£2.50 from Euro Car Parts) and we now have a single wipe action. Result!


January 2014

One of the biggest disappointments with the older model Porsche, is the weak headlights.
I fitted an after-market HID kit from ToreB – a Porsche specialist in Oslo. Here is a before and after picture (on Tore B’s car)…….

HID's

993 HID High Intensity Discharge (xenon) low beam light kit, specially designed for the Porsche 993 with easy installation inside the headlight enclosure. Installation time was 15-20 minutes without the need of any special tools.

No wire cutting, T-Light use the original halogen bulb connectors. Three times the light output of halogen bulbs, high quality (Philips OEM) electronics and bulbs, long life.
35W H1 HID/xenon low beam
Ba9s LED bulbs for front park/marker light with matching colour
Very quick installation inside the headlight housing (bolt-on)
Plug-and-Play connection with easy revert to halogen if needed
4300K light colour resembles the colour of the original Porsche Litronic HID lights.

December 2013

Well – It turns out that the headlight switch in the 993 is supposed to illuminate?
Mine didn’t – and I don’t think a lot of others do either….

I fixed this by pulling off the light switch top (you do have to pull hard but it will just pull off), pull out the exposed bulb left behind, push in new bulb (leave ignition on so you can check the bulb works) and then push the knob button back on (It does have a small grove so is directional with the bulb upside down when you push back on)

Here it is working as it should……

The neatest thing about this is the small reflection you see in the drivers mirror when you just have the sidelights on!


October 2013

I discovered an Alarm trigger fault:

After arming the alarm system, the operation of all actuation circuits is checked by the control unit.
If no fault condition is established there is a rapid flashing of the LED’s which lasts around 10 seconds.
After 10 seconds, all alarm circuits are armed and the door cap LED’s flash slowly.
If the control unit detects a fault, the door cap LED’s will not flash at all during the 10 second system check arming period
A fault condition is then displayed by double flashing of the door cap LED’s after the 10 second system check arming period.

The flashing LED’s in the doors started double flashing every second instead of just once a second. This would point to an alarm trigger fault. It was clear that the doors, door pockets, luggage compartment, engine compartment and glove box were closed, so one of the trigger switches must be faulty. I found that the glove compartment door was a little out of square, so the trigger switch for the light was not being depressed properly by the door when it was closed. I also found that the bulb was missing.
I released the 3 screws under the glove box, and re-aligned the door so that it closed properly. This stopped the alarm fault. I also replaced the missing bulb so this now works properly.

Glove Box


October 2013

I finally replaced the old stereo, and removed the 90’s style 10 disk CD multi-changer while I was at it. The removal provides additional space in the luggage compartment, and this little lot weighed nearly 5 KG!
I’ll be keeping this in the box of bits in case I ever wanted to put it back to original specification. Believe it or not, this is the original factory equipment!

I replaced this stereo with an after market Alpine model (CDE-174BT), but retained the existing external amplifier and Nokia Digital Sound Processor under the seat and in the drivers door pocket. At least now I can play CD’s, DVD’s, iPod, Blue-Tooth phone and Sat-Nav from the iPad


September 2013

Fixed the erratic heating system:
I had a problem where I was getting hot air only from the driver’s side vents, and any temperature from the other side.

FIX: Remove the two kick panels in the front foot wells. This is a five minute job, as they are held by just two Allen bolts on driver’s side and 2 screws and a turn-buckle on the passenger side. Release the clamp from the servo so that you can pull it out and see the butterfly.
With the ignition off, they should both be closed. Turn the ignition on and adjust the temp on the ‘Climate Control Unit’ (CCU) – both Servos’ should open at the same rate. One of mine was sticking open, and when I swapped them over the fault followed the servo – which implied that the CCU is OK and I required a new Servo.
It turns out that if one of your Servo’s is stuck open, the CCU can’t compensate and you get all sorts of erratic behaviour (and risk damaging the CCU). I replaced the faulty Servo, and all appears OK now.

Thanks for ToreB’s help at: http://www.bergvillfx.com/
