Buying a Porsche 997.1 GT2

The 997.1 GT2 is part of the 997 generation (2005–2012). This lesson covers what it really sells for, what moves the price, what to check and how to look after it.

• Manual-only, rear-drive twin-turbo: most powerful road 911 sold at the time
• VTG turbos borrowed from the 997 Turbo
• PCCB and PASM standard

Options that matter

The factory options most often fitted to the cars we track and what they cost new. What each option does to the sold price is on 911 Tracker with a free account. Check every option on the VIN with the VIN decoder before you pay for it.

What to look for

• Coolant pipe fittings (glued/bonded) pulling out

  The GT1-derived Mezger engine's coolant manifolds use aluminium pipes bonded into cast housings; after many heat cycles (especially track use) the adhesive can let go and a pipe can pull out, dumping coolant, sometimes onto the rear tyres. Applies to 997.1 GT2 (BBI Autosport and Shark Werks list it among affected GT1-block engines). From the 911 Buyers shop: this is mainly a concern on cars tracked hard for long sessions; we don't see it fail often on cars driven on the road. Pinned pipes are still a plus when you buy or sell.

  What fixes it: Pipes pinned (or re-bonded/welded) in the housings; normally an engine-out job, often combined with clutch/other work.

• Carbon-ceramic (PCCB) rotor wear/cracking

  PCCB discs (standard on this car) are condemned for chips, cracks or small amounts of wear; replacement is very expensive, and many cars have been converted to steel. Mostly a concern on tracked cars.

  What fixes it: Inspect rotors (and pad thickness) before purchase; replace damaged rotors, or convert to iron rotors.

• IMS bearing (997.1)

  Still present on the M97, but the larger bearing fails far less often than on the 996. It cannot be replaced without opening the engine.

• Bore scoring (997.1)

  More common on the 3.8 S. A borescope is the only way to know before you buy.

• Coolant pipes and radiators

  Same front radiators as the 996; check for debris and leaks.

• PDK (997.2)

  Reliable; check the software and that the fluid was done on schedule.

Intervals are whichever comes first, miles or years. "Porsche factory (converted from km)" means Porsche's own figure for another market, turned into miles with the same km-to-mile pairing Porsche uses in the US.
