Our engines are built up to the highest standards, using all new replacement parts, all reconditioned parts are selected/inspected, chemically cleaned, re-inspected / crack-tested and manually finished before use. New parts are used throughout and checked in the same manner. We only ever build to exacting standards.

All of our A series engines are rebuilt and fully reconditioned to the highest standards using good quality brand named parts. This means that whether you are purchasing a standard re-manufactured unit, or one of our improved units, the same attention to detail and quality of components are used, for examples, We use race quality cam-followers in all of our builds, this is due to them being sized correctly and with a larger contact point for the lobe.

We use competition head studs in our standard and stage 1 builds and ARP studs in our Stage 2 upwards. We have tested every part that we have used and where there have been problems, we have sourced and tested alternatives, this has meant that our build prices might be slightly higher than others but it also means that you are buying the best in reliability and performance. We want each customer to experience the engine exactly as it should be. We stand proudly behind our engines and offer a full warranty for all road units. 

Each build is backed by a catalogue of photos and where possible video, upon completion we issue a build booklet, filled with all part numbers, engine specification, test results, warranty and installation instruction.

​

Please note: Where a customer supplies their own engine for reconditioning or modification, we will use that engine and its components unless there is a defect or fault that does not allow for a rebuild. At this point a suitable like for like will be used from our core stock. For 1275cc based applications, We have MG Midget / Austin Healey Sprite and Morris Marina core units. For reconditioned standard road units, unless otherwise requested we will just pull the next core from stock. For our GT and RS packages we will pick the next cores that are either Standard or on their first oversize and will be built using EN16T Crankshaft. Race applications, where the regulations require a specific engine casting we will build using that exact casting, where the regulations are open with engine variations, we will build using the next cores that are either Standard or on their first oversize and will be built using EN16T (or where applicable EN40B) Crankshaft.

If you have an exact requirement, please specify at the very start, make it clear. What ever the application, we will pick the most suitable core and machine to exacting standards, you will receive the very best engine for your application. That's an MCCS promise.
