There’s no question that a 5.3-liter LM7 with a cast iron block and aluminum heads is one of the best bangs for your buck as far as horsepower goes. Add a generously-sized single turbo, swap it into your ride of choice, and you have yourself one hell of a fast ride for very little money.

The same goes for this LS-powered notchback Mustang; it’s a cheap car to obtain, very easy to swap an LS into, and they’re pretty light. The LS Fox in the video above employs a run-of-the-mill 5.3-liter LM7 with a hefty Forced Inductions BorgWarner S484. The 88-mm turbo sends the hot air to a PT-3000 liquid-to-air intercooler behind the rear seat for a cool charge, and then back through the firewall to the intake manifold. You’ll notice that the intake manifold is just a factory truck unit flipped backwards with a 4-inch V-band.

The modifications listed are good for 9-second quarter-mile passes all day in this Mustang, with the exception of one 8.89 pass at 154 MPH. After the race against the green Mustang, the other races were eighth-mile races. It was still exciting to watch the car hook at the line and make passes almost straighter than an arrow – the car tracks amazingly.

There were two races in the video that we wanted to point out, and those pairings were against the Nissan GT-Rs. The LS Fox clobbered the GT-Rs in the quarter-mile and eighth-mile without even breaking a sweat. Maybe the silver GT-R would’ve had a better chance if it didn’t spin, though. We love the fact that big horsepower can be made for very little money; five-times less money than a GT-R would cost, as a matter of fact.
