  1. The issue I have found with my 3.2 Carrera on downhill hairpins is the amount of effort required to steer around the corner which severely limited my speed and confidence. I mentioned this to Center Gravity and Chris reduced the castor to 5 degrees 44 min. The toe is 7 or 8min. On my recent trip to Austria and Italy including the Dolomite this made all the difference, and I was able to keep up with the 996s, 997s and a Cayman R.
  2. Mine lived on the south coast (Hastings) for the two years before I bought it. In the UK any old 911 will eventually rust unless it is hardly ever driven and stored. Some will need sorting earlier than others depending on their use and how well looked after. Unfortunately the body design allows water and mud to accumulate in certain areas underneath ultimately leading to corrosion of kidney bowls and b posts amongst other bodywork parts.
  3. In my experience given the mileage it will soon need kidney bowls and b posts repairing if they haven’t been done already. It was the same on my 3.2 and I ended up with a full respray for a year after buying costing around £10k.
  4. Yes correct I had a valance from a SC put on. It saved a bit of weight as did the smaller washer bottle for which the concentrate washer fluid bottle was repurposed as the main windscreen washer supply. So far I haven’t needed to refill it in 2 years as car not used in winter.
  5. I can confirm that Johny’s Classic Retrofit system works fine on my 3.2 Carrera with the standard alternator and a 85 Ah battery. Today was a good test as stationary in a traffic jam in 31C ambient temperature for 20 min near Lake Garda in Italy. The a/c kept us nice and cool.
  6. I would agree with everything that's already been said. I was in a similar position to you back in 2013 and was considering anything from a Carrera 3 to 3.2. Prices were just starting to rise at that time due to 2013 being the 50 year anniversary of the 911, so I didn't want to spend too long looking. The situation is different now and prices might even fall over the next few years. In the end I ended up buying the first good condition (bodywork and engine) IB I found that wasn't Guards Red (not my favourite colour for 911s). I ended up with a1988 G50 3.2 sport in GP white and have not regretted it. To be honest when I bought my 3.2 any IB felt so different to drive than any other car (my daily was a 986S) I'm not sure I could have made a realistic comparison and choice between 3.2 and SC. However, the situation is different now as my wife has a 1982 SC which she bought in 2014. We have used both for driving holidays on the continent for the last few years so I now have a good idea of the differences. I definitely prefer my 3.2, whereas my wife prefers her SC. I believe this is down to personal preferences and difference in our physical sizes and proportions The key differences for me are the gearboxes, clutch operation and seat height. Let me explain further. I find the G50 gearbox lovely, and don't have to concentrate on changing cogs as it never baulks. It always gives me the correct gear when i want it. This is not the case with my wife's SC, where I have to concentrate for nearly every gear change to ensure the correct gear is selected. It helps to give a little throttle blip for both up and down gear changes when the clutch is depressed. Also I find the cable clutch on the SC more awkward to use compared to the hydraulic clutch on mine, which doesn't help for seamless gear changes either. I have also discovered that Porsche lowered the seat position for 1988-89 3.2s which enables me to attain an acceptable driving position for pedal operation and steering even though I am only average height (5ft 11in). I think I have oddly proportioned legs which are disproportionately long between the hips and knees. In my wife's SC my driving position is compromised, but this may be due to my odd body shape. The above is a personal perspective of the differences between the two cars. Whether it is the same for you depends on your own personal preferences and physical size/proportions. Below I present the main actual differences that we have found from running these cars over about 20k miles. I have found there is no difference in straight line performance. The extra power of the 3.2 is negated by its extra weight in G50 and sport form, approx 130 kg between our two cars. The front and rear spoilers on the sport version definitely improve stability at high speed. The 3.2 feels heavier because it is. Both have similar steering feel and ride similarly. I have not noticed the claimed extra dinginess of the SC's engine. The SC's engine doesn't run as well at higher altitudes in the Alps. However, the 3.2 can be jerky around 30 mph (fuel saving cutoff issue I believe). We have found my wife's SC to be less reliable due to electrical problems (mainly CDI box failures), although the DME relay failed on my 3.2 recently. To be fair the SC has done ~70k miles more. Both cars have benefitted from Classic Retrofit fuse boards etc. The ventilation and heating is better on the later 3.2 models as the dashboard vents are bigger. Both cars have had full bodywork restorations in our care, even though there was little visible sign of significant corrosion when they were bought and we both know what to look for in IBs. The SC's restoration cost twice as much, but then it is 6 years older and has done 50% more miles. Hope my very much personal perspective on the 3.2 and SC helps.
  7. I have just removed the luggage compartment light bulb in my 1988 3.2 because it has blown. I can confirm it is 10 W and the light fitting is as in Robin's photo above. The writing on the bulb is Lucas R1 10W 12V E2 2G4 K8. I haven't yet been able to find somewhere that sells this type of bulb apart from Eurospares.com which want to charge around £9 postage for a 35p bulb!
  8. The running costs on my 3.2 are much higher than £1000/y, more like £3500/y. Either some of you are hardly using your cars or are living with faults. This year for example I had a single bill for £3500 which covered sorting out an oil leak from a seal between engine and gearbox (oil had leaked on to clutch, so new clutch needed), new front callipers, new braided brake hoses (admittedly this was not essential) + a few minor items. Also just spent £250 to get a front indicator working due to a bodged connection when the car was reassembled during bodywork restoration 2 years ago. I do about 5000 miles a year in my car. Admittedly some of previous years expenditure has been associated bringing the car condition up to a good standard, e.g getting suspension sorted, but these are old cars and you have to expect equipment to fail such as wheel bearings, electric seat switches, wiper motors, fuel lines, seat clips etc. Still even at £3500 a year and the car appreciating in value, it is cheaper than the annual depreciation on a new Porsche, and much more fun to drive and own.
  9. Excellent video. It brought back memories of Gina and I's trip to the Pyrenees this year which was just a few days after when you were there.
  10. Another recommendation for Turbo Thomas here. I have 2 in 1 out silencer + straight through pre-silencer. It makes an awesome sound when accelerating but is not intrusive or boomy on the motorway. Also makes lots of pops and crackles which are fun.
  11. I rang up Porsche reading to enquire about the new Pirelli P Zero Rossos designed for classic Porsches. They have had quite a few enquiries but as of last week had not received any tyres to supply. As my rear tyres are marginal I couldn't afford to wait so have had four SO2s fitted through BlackCircles for £310 all in (16 in wheels).
  12. You are certainly correct about the Spanish roads. Gina and I drove the N260 from Ripoll to Ainsa today in my 3.2. It's a awesome road with light traffic too. We both agreed it's better than the Route Napolean which we did on Wednesday. We're heading further west on the N260 from Ainsa tomorrow.
  13. I believe the MOT values are the concentration in the exhaust pipe. As soon as it leaves the exhaust in to fresh air it is diluted substantially. Leaks into the car from defective headers would be diluted to some degree, but by no means to safe levels.
  14. As a safety professional I strongly urge you to not ignore the risk from CO. The levels produced by impact bumpers cars is not trivial. My 3.2 was putting out 1.74% CO at its recent MOT (pass up to 4.5%). The effects of various concentrations of CO are shown below: Concentration Symptoms 35 ppm (0.0035%) Headache and dizziness within six to eight hours of constant exposure 100 ppm (0.01%) Slight headache in two to three hours 200 ppm (0.02%) Slight headache within two to three hours; loss of judgment 400 ppm (0.04%) Frontal headache within one to two hours 800 ppm (0.08%) Dizziness, nausea, and convulsions within 45 min; insensible within 2 hours 1,600 ppm (0.16%) Headache, increased heart rate, dizziness, and nausea within 20 min; death in less than 2 hours 3,200 ppm (0.32%) Headache, dizziness and nausea in five to ten minutes. Death within 30 minutes. 6,400 ppm (0.64%) Headache and dizziness in one to two minutes. Convulsions, respiratory arrest, and death in less than 20 minutes. 12,800 ppm (1.28%) Unconsciousness after 2–3 breaths. Death in less than three minutes. Assuming that the CO concentration is diluted by a factor of 10 in the cabin you can expect a Headache, increased heart rate, dizziness, and nausea within 20 min; death in less than 2 hours. Last year we were ran the engines from our two impact bumpers for a short time in our garage with the main door open. A side door that connects to our house was open and about 30 min after turning off the engines the CO alarm in our kitchen about 30 m from the garage went into alarm.
