Not all rebuilds are alike! Follow the steps we take to ensure that you are getting the finest rebuilt Mini engine available anywhere.
Start with the men who will be doing the work: Steve Maxwell and Mike Kearney have been building championship winning Mini engines for over 35 years. Together, they have won four SCCA National Championships with the Fortech Mini. Steve and Mike are the only staff members who build customer engines. Seven has its own fully equipped in-house machine shop with the most modern equipment in the industry. This means your project will be handled by a Mini expert from start to finish. Every engine project from the standard rebuild to the most exotic all-out race specification gets the same attention to detail that has made Fortech Racing Engines champions on the track, and show winners for the street!
Quoted horsepower numbers are not the way to choose who will be your Mini engine supplier. Seven does not want to be part of the horsepower number game. We are the SCCA National Champions, so we think we do know something about performance, and the best way for you to optimize your engine within your budget.
The following description is of our machining technique for a 1275 Mini power unit rebuild.
All of Seven's rebuilt power units are built from late model Mini or MG Metro donor cores. Our British agent hand-selects the best available cores before they are crated and shipped to California. Every engine assembly is carefully inspected in the tear-down phase to look for potential problems.
The disassembled parts are sorted, the core and oil plugs are removed from the block, and the block is cleaned in our Storm Vulcan spray washer. The engine parts are then cleaned and glass beaded where necessary. Every effort is made to keep the disassembled core parts together for each rebuild; this way you do not get mismatched gears and other rotating parts.
Main bores are checked to be sure they are straight and to specification.
Every engine we rebuild at Seven Enterprises is fully balanced: crankshaft, connector rods, and pistons, and finally the complete assembly, balanced on the Stewart-Warner balancing machine.
The transmission is fully disassembled, cleaned and inspected. All necessary parts are replaced to bring the transmission up to Seven's standards.
Each engine is carefully assembled, cam timing checked and adjusted to grinder's specs.
The engine is setup on the Seven Enterprises engine test stand to be fully tested and run-in.
Finished power unit ready to ship. (deluxe shipping crate at extra cost)
