Porsche 911 Turbo 997.1 buying guide
The first 997 Turbo, built from 2006 to 2009, pairs a twin-turbo 3.6 with variable turbine geometry turbochargers and four-wheel drive. Its engine is a different design from the 997.1 Carrera's, and specialists don't associate it with the Carrera's bore scoring or intermediate shaft bearing faults.
The versions
- 3.6 twin-turbo flat six, 480PS, with two BorgWarner variable turbine geometry turbochargers
- Sport Chrono adds an overboost function for up to ten seconds
- Four-wheel drive managed by Porsche Traction Management (PTM)
- 6-speed manual or 5-speed Tiptronic S automatic
- Coupé from 2006, cabriolet from September 2007
What to check on a 997.1 Turbo
3 model-specific things to look at when you view one. They're a starting point, not the full inspection.
Coolant pipe fittings
What to look for: Ask whether the engine's coolant pipe fittings have been pinned or welded, and look for the invoice. Check the coolant level and look under the back of the car for coolant residue.
Why it matters: The tubes that carry the coolant hoses were bonded into the engine's coolant housings with adhesive, and heat cycling eventually softens it, which can cause a sudden coolant loss. Securing them needs the engine out, so specialists expect to see it done on a car of this age, and paperwork for it is a sign of a car that's been looked after.
Front radiators
What to look for: Shine a torch through the openings in the front bumper at the radiators behind. Look for stone damage, packed leaves and corroded fins. On the drive, check the air conditioning blows cold.
Why it matters: The radiators sit low in the nose and take stone chips and debris. Damaged radiators are a common replacement, and some owners fit reinforced mesh grilles to protect them.
Over-rev record on manual cars
What to look for: Ask for a diagnostic readout from a Porsche centre or specialist, or have one done as part of an inspection. It shows how often the engine has gone past its rev limit.
Why it matters: On a manual car, a missed gearchange can over-rev the engine. The engine computer logs these events, so the readout shows how the car has been driven and flags anything that needs a closer look.
