Greetings,
Having owned a '99 996 last year, I am considering the purchase of a 1994 993. The decision taken due to financial considerations first and my interest in really owning the mean machine you guys describe being a different kind of experience!
The car is immaculate, arctic silver, 6sp manual, gulf specs which is important for this country, black inner trim with wooden parts (if only jen could send me my pic upload password!).
Though i didnt drive it (was shy to ask the owner to step aside!) the feeling of the 993 was totally exhalirating. It's a go-kart relative to the 996. The engine sound and the tunes the exhausts produce are in no way compared to the 996's.. I did notice a lack of power comparativelt but I dont think i will really need more on UAE roads.
I do have some questions though:
1- The mileage is 130,000km. The engine does not produce any smoke and is hi alive thru the rpm range.. Is this ok for an oil cooled?
2- There seems to be a backfiring bang and lots of crackles when the rpm's go beyond 6k and drop back.. Is this normal? The car had gembella exhaust and later changed to regular exhaust (the gembella trumpets were way to loud!)
3- Is it possible to change the wood trim? to what? at what price?
4- Now this is going to irritate some, but coming from the 996 world, I would like to ask generally: how reliable is this car compared to 996? ouch! pls dont let it hurt!!!
Thanks for any reply,
Wael

crackling etc yes its absolutely normal... you should hear how my race car does when I lift with the Supercups on! Absolutely awesome!
The wood trim if you go factory its going to costa ya, more like a couple of thousand USD. In reality the wood trim is stick on to the same panels so you can get some immitation wood stick ons like the ones the sell on ebay for 100 bucks and try them out. If nothing else you did not spend 2 grand for nothing...
Finally the 993 is bullet proof, besides the fact that you need to check if the wiring harness has been replaced with a new one under the official Porsche recall last year. Other than that no major problems , just wear and tear. I cannot compare that with the 996 as I naver owned one but I can tell you that I own 2 993's and both so far have been very reliable...
Good luck!

It looks great!!! Funny thing is that you have the black bumpers like a US model, but it has the 3rd light mounted ontop of the rear windshield instead of the hoop as seen on 1994 models...
Enjoy the ride!

Hi Wael,
The US style bumpers are standard in the Gulf, my Oman car from '95 has them also. I have attached a picture with the US style 3rd brake light in the "basket handle" a hoop like spoiler just above the engine lid. It was dropped after the '95 model (and the US didn't get the 993 in '94)
If you are buying private why don't you ask Juergen at Al Nabooda about the car's history, or take it there for an inspection?

Those don't appear to be stock exhaust tips or a type that clamps on the stock exhaust. Is the car very loud? They appear to be round like supercups. Unless, of course, that is a picture of the car when it had the Gemballa "trumpets" on it. Good luck with the car!

1- 130,000 km is not excessive, but do make sure the scheduled maintenance has been done. The 96,000 km service is a major/expensive service. Airbags have a scheduled maintenance check at 8 yr. As mentioned, when properly maintained, the 993 is extremely reliable.
2 - Off throttle crackling is OK, backfiring is not.
3- I assume from your post, the car has wood trim which you want to remove. My guess is likely no better than yours about whether you'll need to replace or refinish the applicable trim pieces in vinyl/leather, but I doubt the wood will come off w/o damaging the existing trim.
4- Can't compare 996 v 993 reliability, but I do know the 996 is far more likely to develop coolant leaks - well, actually, I've got a slight lower valve gasket leak, so maybe not

Thanks guys for the replies...
The car is my business partner's own.. He really wants to sell it coz it's a manual and he wants a tip since he's bothered by changing gears.. (guess it's a matter of taste after all..) He's not had it for long though.. It has had its service last and the wiring harness was changed indeed.. Also, the steering pump (or rack?) was also changed.. Xenons were fitted a few months back.
The tips on this car were the ones on the Gembala's. I think they kept them instead of putting the std tips of the std exhausts that were fitted..
The car has been serviced by Hamman House for over a year now.. So far it has a clean record.. I can say that it is properly maintained.
I guess i will worry about the wood trim if and when i own it..
Dan: 1) what do you think is causing backfire? 2) reliability issue, you said '..cant compare' meaning it is more reliable than 996? I did have overheating pbms in my previous '99 996
Thanks for the replies!

I have the same misfire in my 95 993 with stock muffflers, my issue is that the catalytic exhaust has been emptied from the inside..I love the sound though.
cheers

The backfire is unburnt gas igniting somewhere aft of the engine (i.e., in the exhaust system). There could be several causes, best diagnosed by a competent shop.
My comment that "can't compare 996 v 993 reliability" meant I have no basis to make a comparison since I've neither owned a 996 nor investigated its reliability. Sorry for the confusion.
