Home/Buyer's Guides/997.1 GT3
The analogue purist · 2006-2009Motorsport without a filter: prices, weak points, technical checks and a checklist. So you can assess the history, the engine and the clutch with confidence before you buy.
The Porsche 911 GT3 of the 997.1 series is more than a sports car. It is a homologation model for motorsport and offers a driving experience of rare purity. At its heart is the legendary 3.6-litre naturally aspirated Mezger engine with 415 PS and an intoxicating rev limit of 8,400 rpm.
That engine is based directly on the block of the Le Mans-winning 911 GT1. It has genuine dry-sump lubrication with an external oil tank and is, by design, entirely free of the IMS (intermediate shaft bearing) and bore scoring problems that can afflict the ordinary 997 Carrera engines. But this icon too calls for specific expertise when you buy.

The block is bulletproof, but the ancillaries need attention.
As on the 997.1 Turbo, this is the most important technical checkpoint. The coolant pipe connections on the engine block are only bonded in place from the factory.
The engine is extremely durable, even in track use. There are still points to watch:
The six-speed gearbox is very robust. The weak points are the wear items:
250 to 600 pages of specialist knowledge (depending on the edition) on the 997.1 GT3: detailed weak points, engine codes, specification details, inspection checklists, production figures, the options that add value and price forecasts.
The GT3 is robust, but motorsport engineering has its price.
