Engine Building, design & development
Porsche Engine Rebuilds, Inspections, Diagnostics, Development and Tuning
At MCE we take a systematic approach to investigating engine issues and undertaking rebuilds, and draw on over 35 years involvement in designing, building and testing road and race car engines. We have extensive experience in rebuilding all the Porsche 911 air-cooled engine variants (and engineering expertise carried-over from years in Cosworth, Jaguar and Aston Martin engine design and build) from the early 2.0L 901 aluminium case assemblies through to the magnesium case '73S and RS installations and later 3.0SC, 3.2, 964 and 993 variants, from standard road specification through to race-proven RSR configurations. We also utilise a full suite of diagnostic tools including combustion chamber borescoping, compression testing, leak-down testing, oil spectrometric analysis, precision measurement and in-house computational analysis where required. Please feel free to get in touch to discuss your requirements.
1974 3.0RSR FIA Race Engine: MFI, twin-spark ignition, slide throttles, polished & ported heads, boat-tailed case, HC pistons, centre-feed cams and lightweight valvetrain
3.0SC 'hot-rod' engine converted to 3.2L short-stroke with HC pistons, GE60 cams and 46mm PMO carburettors
Early 1965 901/01 Solex Carb engine rebuilt to original factory specification
From left to right: 1968 2.0 911S, 1976 Carrera 3.0, 1974 3.0 RSR FIA engine rebuilds
1968 2.0 911S engine rebuilt to original factory specification
1973 2.4 911S engine rebuild
All engines are stripped down to full crankcase separation and rebuilt in-house, for close cooperation with customer on rebuild specification and modifications for reliability and performance
1976 Carrera 3.0 Engine Rebuild Complete
Cylinder head inspection, machining and rebuild, including valve guide replacement, valve seat machining, combustion chamber polishing, port flowing and matching.
Engine Tuning & diagnostics
Camshaft measurement and analysis: Considering some engine modifications but not sure which cams to select? At MCE we have some very useful tools developed in-house to help assess camshaft performance in an engine well before the engine is built, saving considerable build time and dyno iterations.
These tools can also assess valvetrain loads and response to engine speed, helping to define rev limits and suitable rocker and valve hardware specification on any custom build.
We have capability for full carburettor strips, vapour blasting, ultrasonic cleaning, throttle shaft replacement including oversizing of excessively worn bores, zinc passivation, rejetting and rebuilding with new seals and gaskets. Once rebuilt, we also offer an in-car set-up service to perfectly match the carburettor's fuel delivery with the specific engine demands.
We have the tools and capability to conduct Bosch MFI pump adjustment, recalibration, rebuild and tuning
For engine fuelling and ignition tuning, carburettor jetting and balancing, MFI and CIS tuning, we can conduct part-load and full-load AFR calibration and optimisation.
If required, we can also conduct rolling road dyno tuning and performance optimisation.
