Project Porsche 924 Turbo gets tested

British law says that cars over three years old must have an annual safety inspection, known here as the MoT (Ministry of Transport) test. Racing Restorations UK recently took our Project 924 Turbo for its test. It’s the first step in registering the Italian-plated Porsche here in England.

The test checks what you’d expect:

• Body or vehicle structure free from corrosion or damage, engine mountings secure etc. Fuel system: No leaks. Security and condition of pipes or hoses. Fuel cap fastens and seals securely.
• Exhaust emissions: dependent on the age and fuel type. Exhaust system: secure & complete. Catalyst where one was fitted as standard. Without leaks and is not too noisy.
• Seat belts: checked for type, condition, operation and security. All seat belts must be in place. Seats: driver’s seat can be adjusted. All seats for security and seat backs can be secured in the upright position. Doors: Latch securely. Front doors open from inside and outside. Hinges and catches for security and condition. Mirrors: minimum number required, condition and security. Load security: boot or tailgate can be secured in the closed position. Bonnet: securely latches in the closed position.
• Brakes: condition, inappropriate repairs or modifications, operation and performance. ABS or electronic stability control (ESC) where fitted. Tyres and wheels: condition, security, tyre size and type and tread depth. Spare tyres are not inspected.
• Registration plates: Condition, security, colour, characters correctly formed and spaced. Lights: Condition, operation including HID and LED headlamps for cleaning, self levelling and security. Headlamp aim. Main beam warning light.
• Wipers and washers: operate to give the driver a clear view ahead. Windscreen: condition and driver’s view of the road. Horn: correct operation and of suitable type. Steering and suspension: condition, steering oil level, operation, a check for inappropriate repairs or modification including corrosion to power steering pipes or hoses. Operation of steering lock mechanism.

After an hour’s worth of checking, the 924 failed, but only on a few things.

First was the headlamps, which are left hand drive and dip to the wrong side. Track rod ends and one rear wheel bearing were past it. There’s a problem with the rear fog light being intermittent, the windscreen washers don’t work and it needs new wiper blades. The tyres passed but they are pretty old, so we’re changing them.

Rob at Racing Restorations will do the track rods and wheel bearing, I’ll swap the lamps and fix the other bits from my stock of 924 and 944 parts and we should be good for a re-test next week. Then I need a letter from Porsche confirming the build date, and we’ll be ready to submit a registration application.

The boys say it drives well: worn second gear synchro being the only real issue. My transmission guy has our spare gearbox apart and apparently it’s not pretty, with worn selectors on 1 through 4. We’re still trying to figure out what bits Porsche and Getrag used in the early 924 Turbo gearbox: must be Mercedes or similar from the period. More news on that as we find it.

As an aside, I’ve just bought a complete 924S back end including the aluminium arms from a mate, so that might come in handy. Aluminium arms will be nice if we go for this Carrera GT idea and try for trick underpinnings – same as fitted to 944 Turbo.
