Engine and Transmission Builds
Porsche Engine Rebuilds, Inspections and Diagnostics
At MCE we take a systematic approach to investigating engine issues and undertaking rebuilds, and draw on our 30 years experience designing, building and testing road and race car engines. We also utilise a full suite of diagnostic tools including combustion chamber borescoping, compression testing, leak-down testing, oil spectrometric analysis and precision measurement to accurately identify issues and overall engine condition. We have extensive experience in rebuilding all the Porsche 911 engine variants from the early 2L aluminium case air-cooled assemblies through to the later generation 996/997 M96/M97 water-cooled installations, from standard road specification through to race-proven RSR variants. 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
On the left: rebuilt 996 engine with new pistons and cylinder liners. On the right: 1973 2.4S MFI engine rebuilt to original factory specification

1968 2.0 911S engine rebuild to original factory specification
1973 2.4 911S engine rebuild
M96 and M97 intermediate shaft bearing (IMS) and rear main seal (RMS) inspection and replacement

1976 Carrera 3.0 Engine Rebuild Complete
IMS bearing failure on a 2005 997 engine (late M96 type). We caught this one following diagnosis of a running, yes running, engine, and were able to initiate a more efficient rebuild before complete collapse caused further internal damage.
The photo above shows the earlier original single-row sealed Porsche IMS bearing on the LHS, prone to premature failure. On the RHS is an updated higher-capacity internally lubricated roller-bearing design: a recommended upgrade in all M96/M97 installations.
Air-cooled cylinder head inspection, machining and rebuild, including valve guide replacement, valve seat machining, combustion chamber polishing, port flowing and matching.
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.
Rectification of engine liner fatigue on 996 and 997 models (the infamous 'D-chunking' of the cylinder wall)
