If shopping for a 993, are there any particular years one wants to avoid? As well what are some issues one wants to pay closer attention to for the respective years?

I've heard to stay away from '95s due to their suspension..

Hi

I have hard of no such thing with UK cars. The non varioram have simpler induction systems due to the lack of varioram. The earlier cars are also non OBDII which can have smog related implications. Buy on condition.

Best of luck with your search.

Here are the relevant facts re the early suspension changes



That said all 993s from any year will have to have all their bushings, shocks and probably their ball joints replaced at this point.

For RoW cars there are no years particularly worse than others some don't like the heat setup in the '94s which was like that used in 964 rather than the later 993 setup. Some don't like the g50/20 used after '96 as opposed to the G50/21 used for '94-96 because of the gearing, but those are just minor things.

For US cars, there's a huge difference between the '95 OBDI cars and the '96 up OBDII cars, the early cars being far easier to modify and get through any smog inspections, within the later group the '97-98 are easier for a hotrodder to deal w/ because of the DME design, guys that want to chip a '96 need to first get a '97-98 DME.

Stay away from '99 and up and you'll be fine.

Hi

If they are like the UK cars then some of the early (1994) non varioram cars will have the 964 cam and sprockets. A good thing if so.

Actually I disagree on the rear suspension arms needing replacement by now apart from the A arm rose joint. Top mounts probably, front bushes yes for sure.

All the best

As usual, Bill delivers...

So I have a '95 (build 3/94, according bill above "production version 3") and bought the shop manuals from pelican a while back, but am still quite over my head on all these technical details.

One question: how do I verify the extent to which these manuals apply exactly to my car, if so many tweaks have happened during the production runs?

Love this place!!

The only issue I'm aware of has to do with late '97 and '98 models which can have faulty head gaskets. Most cars were repaired under warranty in the first few years of service, but it's mileage/heat cycle related so the lower mileage cars might not have failed before the warranty expired. The failure's I've seen are fairly profuse leaking from the left bank of cylinders (both times it was the number 1 and/or 3 cylinder leaking at the base IIRC) .. many times it's not so bad as to require immediate repair, but it can get messy. Not all '97/98 models had this, but it was a big enough number for Porsche to issue a TSB to the dealers to look for it at service and repair the ones that failed.

that's funny - I think you beat a lot of us to it
at least it's what popped in my head before opening the thread

If you like driving around w/ bushes like these, which are typical for 10-12yr old 993, fine, but most of us wouldn't like them too much

Bill Verburg

Can you post a copy of that TSB? I never heard of that one. I do have the one which pertains to late 964 and 993 thru '95

Bill ... you know none of us are as organized as you with information .. well, I guess I'll speak for myself here .. I'll have to backtrack and see if I have a copy from my Cab's PPI, I can't remember if the shop actually had it or he showed it to me online. So, there was one on the '95's as well? ..
