Visiting from the 964 board!

I'm going to look at a 1996 993 Turbo with factory 430BHP upgrade and 30,000 miles. I will be getting a PPI. But is there anything that 'goes' at around 30 to 40,000 miles (eg clutch, turbo etc etc.)

Basically I want to as much as possible avoid buying a car and then find myself replacing loads of 'wear related' items in the short term!

Thanks in advance!

A good place to start would be <a href="http://www.993tt.com" target="_blank">Rick's 993TT web page</a>

Click on "buying a Twin Turbo"

It was very helpful when I was looking.

Aside from all the usual advice, I'd have a good look for a leaking steering rack, and a leaky clutch slave cylinder. Also some sort of an oil-cooler fan resistor? These items were all replaced by the previous owner of my car shortly before I bought it 4 months ago. 4 months of heaven, I might add... absolutely perfect and it has 52,000 miles on it.
In fact, I wouldn't even mind too much, if the turbos went out, and I had to replace them (with bigger units, of course). But, they're perfect. Darn.

Watch all 1995-6 turbos for first-gear warping. I had that problem with mine. Take a test drive and, whilst rolling (5+ mph) in first depress the clutch and listen. Any whining is a bad sign.

Badly-treated clutches can go at any time on a TT.

Listen intently for any excessive tappet noise, especially on the exhaust side, since that is a common problem in higher mileage cars. Slapping tappets may be indicative of more expensive valve wear.

Either way, get a decent warranty. Problems can get $$$$$expensive on these babies. If you're still unsure either me or one of the other local guys can pop over to take a look. Good luck.

My addition to the list is tires.The TT has an insatiable lust for them.I run SO2's and see about 7k per set of rears.Fronts last about 12k

Hi Piers,

Welcome! I migrated over from the 964 board as well but did visit this board for tips and advice prior to my purchase of a near perfect '97 993tt.

Good tip this one. Tried two '96s' and both failed. Finally opted for the '97 (they revised the 1'st gear shaft from I believe late '96 on)

Mine had failed. Symptom, oil temp. goes up to ten o'clock on the gauge when stuck in traffic. Anything over eight o'clock with engine off but ignition on should have the oil cooler fan running at slow speed. If it doesn't it means this resistor has failed. It's in series on the low speed circuit of the fan. There's different solutions on this board for this one but all I did was bridge this resistor causing it to run at high speed when oil temps come up to eight on the gauge. Email me directly and I'll give you details as to how I did this.

A great site for info is <a href="http://www.p-car.com" target="_blank">web page</a>.

There's also weak turbo hoses on the earlier cars to contend with, plus you can't chip tune pre '97 cars, you'd have to replace the ECU if you wanted to do that (something to consider if upgrades are planned).

They're great cars, supremely fast but somehow not as communicative as the 964. I've upgraded my suspension from stock with a set of Bilstein PSS-9s' which are great but I've still kept my 964 (even though I can ill afford it!) as she just drives so sweet.

Best of luck on your search Piers, Hope you find a great car! <img border="0" alt="[cheers]" title="" src="graemlins/beerchug.gif" />

Thanks Guys!

I'm planning a look at a '97 (non 430BHP) with 15K miles.

As it's '97 is it a simple chip job to upgrade to 430BHP or is there more to it?!

Did Porsche do anything else for the 430BHP option?

Does it make that much difference to performance?

Thanks in advance!

Changing the ECU is a plug n play operation ( only with a facotry ECU ). Changing the turbos is hard ( ~ 8 hours ). Adding the S oil cooler is not so hard.

If you like doing it yourself, there are some links here: <a href="http://www.p-car.com/diy" target="_blank">www.p-car.com/diy</a>

I'd recommend that you don't get hung up on HP, but rather aim for a well balanced, drivable car. So I would do the suspension first then exhaust, and then spend the rest of your money on DE's and driving instruction. The stock 400 hp is plenty!

Honestly, 30 extra crank horsepower is less than a 10% increase over stock. 10% is such a small number that any number of other factors can affect that ( temperature, gas, cat, exhaust, etc )
