With nearly a month to go until the Classic Restoration Competition comes to a close at the Silverstone Classic event, our 1977 924 Martini Rossi is in the final stages of restoration and has now had its engine fitted.
Kevin Waterhouse, Workshop Manager at Porsche Centre Silverstone, explains what has happened to the car since the last update:
"We extracted the engine and gearbox assembly from the car, completely stripped all the ancillaries from the engine and got to work cleaning what was good and sourcing parts for the components that weren’t. We removed the cylinder head from the engine block and sump pan. The cylinder head was completely reconditioned using new tappets, camshaft, water pump and timing belts and rollers.
All the pulleys and electrical items, starter motor and alternator were stripped and cleaned thoroughly with any suspect parts replaced. We then removed the pistons and crankshaft assembly from the engine block and replaced the pistons and rings and had the block re-bored. The crankshaft was reground and we reassembled the engine using new bearings, seals and gaskets.
The oil pump had to be reconditioned as this part is no longer available and we were unable to source one. We reconditioned the unit and, using other components, we rebuilt it to well within the specification required to do its job.
We then fully reassembled the engine and refit it to the 924 Martini. We also replaced the clutch and components within the clutch assembly. The tolerances within the gearbox were checked and new seals and gaskets were fitted.”

*Data determined in accordance with the measurement method required by law. Since 01 September 2018 all new cars are approved in accordance with the Worldwide Harmonized Light Vehicles Test Procedure (WLTP). You can find more information on WLTP at
. From 01 January 2019, all fuel consumption figures are shown as determined in accordance with WLTP. CO₂ figures will be shown as NEDC-equivalent values, as CO₂ based taxation will continue to be based on an NEDC value (derived from WLTP) until 06 April 2020. For Plug-in Hybrid Electric Vehicle (PHEV) range and Equivalent All Electric Range (EAER) figures are determined with the battery fully charged, using a combination of both battery power and fuel.
Values are provided for comparison only. To the extent that fuel and energy consumption or CO₂ values are given as ranges, these do not relate to a single, individual car and do not constitute part of the offer. Optional features and accessories can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics which may result in a change in fuel or energy consumption and CO₂ values. Vehicle loading, topography, weather and traffic conditions, as well as individual driving styles, can all affect the actual fuel consumption, energy consumption, electrical range, and CO₂ emissions of a car.
