Engine Building, design & development
Porsche Engine Rebuilds, Inspections, Diagnostics, Modification and Tuning
At MCE we take a detailed technical 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, utilising engineering, machining and build expertise carried-over from Mike Champion's experience as a leading engineer within the engine development and manufacturing industry in the UK and Germany, including many years with Cosworth and Tom Walkinshaw Racing, focussed purely on road and race engine development. From the early 2.0L 901 aluminium case assemblies through to the magnesium case '73S and RS installations and the later 3.0SC, 3.2, 964 and 993 variants, we can build from standard road specification through to race-proven RSR and any combination of modified road configuration. We can also utilise a full suite of diagnostic and analysis tools including combustion chamber borescoping, compression testing, leak-down testing, oil analysis, precision measurement and in-house computational analysis where required. Please feel free to get in touch to discuss your particular requirements.
1965 2.0L Race Engine: Restored original Solex carburettors, '65 aluminium crankcase, 66mm crankshaft, custom cams, 9,000rpm rpm limit
3.0SC 'hot-rod' engine converted to 3.2L short-stroke with HC pistons, GE60 cams and 46mm PMO carburettors
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
Early 1965 901/01 engine rebuilt to original factory specification, including centre-feed cams, cam-driven Pierberg twin-fuel pumps, original Mahle 'slipper' pistons and Solex carburettor set-up
2.5L 'hot-rod' engine based on an early 2.0 aluminium 901 case with counterweighted 'S' crankshaft, modified Mahle cylinders with custom HC pistons, MCE gasflowed heads, MCE custom-grind cams and Weber 40IDA carburation
Rebuilds in progress in dedicated build shop
1968 2.0 911S engine rebuilt to original factory specification
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

Engine Tuning & diagnostics
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.
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.
In-house expertise in strip, repair, reconditioning and rebuild of 1965 Solex 40PI-1 carburettor assemblies, including tuning for road and race car applications.
We have the tools and specialist expertise to conduct Bosch MFI pump adjustment, recalibration, rebuild and tuning, including rectification of worn seals, sticking or seized shafts, governor and space-cam adjustment and replacement.
We also conduct rolling road dyno tuning and performance optimisation.
