And the proceeds go to McQueen's favorite charity.

A Porsche 911 built by Canadian tuner Bisimoto Engineering and inspired by Steve McQueen will cross the block at Mecum’s Monterey sale next month, with the proceeds going to the Boys Republic charity.

The styling of the 1980 machine has been backdated to resemble that of a late-Sixties car of the type McQueen drove and raced himself. It’s finished in Slate Grey, the same colour as the 911T McQueen drove in the opening sequence of Le Mans.

Power comes from a Nineties 3.6-litre engine with sequential fuel injection, throttle bodies, a GT3 intake manifold, and a custom exhaust with pulse chambers. Which should produce a rather fruity noise to go with the 316 horsepower output.

It’s got the suspension to cope, too. The factory rear torsion bar arrangement has been replaced by a custom coilover set-up. The whole car is significantly lower, too, with a subtle 1.5-degree slant towards the front.

It should be a pretty epic track weapon, then. And fast, too, as it only weighs 2,400 pounds.

The interior features a four-point rollcage, custom-made, aircraft-style, bare aluminium seats and McQueen’s preferred Momo Prototipo steering wheel. The bespoke ‘911BR’ badge on the engine lid is a neat finishing touch

Mecum has put an estimate of $135,000 to $175,000 on the car. All proceeds will go to Boys Republic, a California community for trouble kids that McQueen credited with turning his life around after he was sent there himself.
