What should I do next to my 993?!
Discussion
Had my 993 a bit over 4 years which is the longest I've ever owned a car by quite some margin. Car gets driven on road and track. Have given her quite a bit of TLC over the years (full details bar the last service here: http://www.pistonheads.com/members/showServiceHist... and her current spec is:
993 C2 manual Cab
Koni FSDs + M033s
Superpro bushes
New top mounts all round (Centre Gravity, checked and replaced a few other bits a couple of years ago)
OMP strut brace
Carnewal RSR mufflers (gratuitous vid: https://www.youtube.com/watch?v=7HzC5cbTkcQ)
Clear lenses on front
HID Kit
Calipers repainted in red and overhaul
Paint and fit front air ducts
Dash clocks refaced in white
I'm starting to get an itch to upgrade/tweak her a bit more. My musings....
- Interior is commensurate with mileage so I do daydream about a retrim about once a year but the cost appears to be pretty mega.
- Cab hood lining could do with some TLC and other than that the only thing that bugs me is the fact that the speedo overreads by 10%+ but apparently this is pretty normal
- remap by Wayne Schofield, although last time I tried to get hold of him I had no joy despite repeated attempts and he is miles away. Also worried about changing the character of the engine too much
- Quaife/Wavetrac LSD, but lots of money to buy and esp fit unless you're doing a clutch etc at the same time I believe, not sure it's worth it.
Was wondering what thoughts people had and whether I'm missing anything obvious?

I think having read your list of modifications you have already done,the next obvious thing would be to trade it in and do the same to a coupe! You could then add good looks to the list of mods.Why do all that to a cabrio
Haha! Expensive! Basically, because it doesn't have super stiff springs etc on it now, it's fine that it's a Cab without the added torsional stiffness of the Coupe. I'd rather save my money and keep a car that I know is mechanically sound, rather than start from a relative unknown

The bottom of the Porsche shield on the wheel centre caps should be pointing at the valve stems.
You should rectify this immediately.

On a slightly less cheerful note, my other half managed to reverse into the rear bumper of the car this morning while piloting our family battlewagon
Quite a feat considering the aforementioned battle wagon has rear parking sensors 
So there's a nice 2"x2" graze through the thickness of the paint. Was quite upset about it this morning but have decided to use it as an excuse to get the bumper resprayed and tidied up. It's still carrying a few minor but visible-if-you-know-they're-there scrapes kindly added by assorted incapable-of-parallel-parking-without-hitting-other-cars idiots before we moved out of London.boxsey said:

If you're going to track it more I would agree with the above. I once had some pax laps in a 964 cab and felt rather queasy due to all the scuttle and shake. 
Anyway, it's not a track weapon (although given its age and power you'd be surprised at what it can keep honest!), for that I have a 620R
Just trying to make it great on the road and also fun on track when I bring it along.boxsey said:

That's a bit odd, was the track very bumpy? I don't recall ever experiencing scuttle shake on track unless hitting a kerb.
No it was Donington. It felt like the whole body was flexing in the corners, especially down Craner Curves. The much softer suspension than my KWV3 equipped coupe wouldn't have helped and nor would not having a steering wheel to hang on to (therefore probably didn't feel as bad to the driver). They weren't particularly quick laps but I still felt a bit green afterwards! Guess I'm just used it!n12maser said:
upgrade your (albeit already upgraded) suspension for adjustable Bilstein PSS10s. The perfect road/track setup
Good idea! Unfortunately I've already had that, see "Tuesday 25th February 2014" entry here: http://www.pistonheads.com/members/showServiceHist...PSS10s were great on track but right on the limits of acceptability on the road IMO even with the 25% softer springs I had :/

Wayne's remaps are superb. 15bhp gains generally. Sharper response and less fluffiness generally. You can get him via Facebook he's worth persevering.
After a couple of years of trying on and off, I finally got hold of him the other day Am booked in for about 6 weeks time, very excited 200Plus Club said:
you may find like i did that you are down on power if its varioram. mine wasnt working right, the car was only doing 250bhp top end. i left with 304bhp!
Not varioram, but Wayne has asked me to check a couple of bits before it gets to him. This was my dyno from a couple of years ago at Surrey Rolling Road....
Incidentally, according to my local aircooled specialist, in order to comply with TuV / type reqs in Germany, all aircooled (and maybe modern ones as well?) cars had to put out factory quoted power +/- 5% to get approval. So one imagines that if you see a bog standard car that's producing over that +5% figure (esp 20 or so years after it came out of the factory ) that's a good indicator that the rolling road may be a bit optimistic
) that's a good indicator that the rolling road may be a bit optimisticJuts picked her up from paint and she looks ace Fresh paint on the bumpers and the rest of the car has been machine polished it seems A little corrosion on the chassis legs was found while she was away and also rectified. Heavy clutch was also sorted - damaged pedal box and assistor spring not assisting. Engine mounts were checked and they're sagging a little but not too bad. Recommendation was to replace them with 993 GT2 mounts which are better and actually cheaper than the standard items, so will do that sometime in the next few months.
Ignition, fueling and vacuum systems all checked out fine so all set for remap by Wayne in 3 weeks
Have decided to leave the short shift kit for a while, as I spent a little more than planned getting the other bits and pieces sorted.
Best recent VFM "mod" has got to be the Bosch Aero Twin wiper blades. Twice the price (a massive £20 or so) compared to regular items, but well worth it.

Overall I am very pleased with the results - the engine is smooth as silk at lower speeds now which is very nice (I always thought it was just me being a bit clumsy with the gas ) and basically a nice little chunk of power has been added everywhere. When she lifts off at 4000rpm to run to the redline it's mega, couldn't have asked for more. And the best bit for me is the character of the power delivery hasn't changed, you still have to work the engine but it's even more rewarding when you do now. And I could swear she sounds even angrier now
Also, kudos to Porsche: after 132K miles and 24 years, her initial dyno of 285bhp was pretty unbelievable. Given that the final power gains weren't silly numbers, the initial number seems pretty reliable. Wayne seemed to think it was one of the highest NVR ones he'd seen, and that the engine def hadn't been assembled on a Friday afternoon at the factory Also, I'd take this as pretty strong evidence that if you fit Carnewal's 993 mufflers like I have there doesn't seem to be any negative impact even on a car with a standard map.
