Both the 3.0L and the 2.5L started out life in a Ford Mondeo, they were then picked up by former owner Lee Noble from Ford for just £400 pounds a pop.
The 2.5L was lightly breathed upon, and dropped into the company's first car, the M10, the engine produced 168 BHP.
The engine in the M10 and original M12 GTO were taken up north to be tuned by a company called John Noble engines (no relation to Lee Noble)
The M12 was the next car to receive the 2.5L engine.
The 2.5L engine in the M12 GTO was a bit more powerful, thanks to it being a bit more engineered and with the addition of twin turbos, it produced 310 BHP.
Unfortunately, the used all the 2.5L engines Ford had, so Lee Noble had to go for a 3.0L mondeo engine, but this time it was tuned by Roush, a company famous for tuning Mustangs
