What Is It?
Noble M400
But, WHAT is it?
British car, with the rolling chassis built in South Africa, then the drivetrain installed at its destination. Most Nobles made their way to the Europe, but 220 of the LHD models made it to the USA. No ABS, traction control, no airbags. It's basically a Porsche 914, but british.
Ok, so... what is in it?
All Nobles start life with a Ford V6 Duratec engine, with two garrett turbos added on, along with a few forged bits. The manual 6 spd transmission is sourced from the Euro-only Mondeo.
For the M400, standard power was 425hp, 390tq.
Now what?
Because it was delivered with a Ford engine, it had problems. After enough of those problems, I set about to swap out the Ford and insert a K24 into the chassis.
