About Nelson Racing Engines

The name NELSON RACING ENGINES has become synonmous with extreme horspower applications.

When professional car builders and car owners are looking to "push the envelope" of power and drivability, they call on NRE.

Whether looking for 2,000hp+ race application, or a 1,500hp street application, NRE has been building turn-key solutions for super motors for over 11 years.

Put simply - we are gear-heads. We love high-horsepower performance and always have. It began with the question: "What if...?" and turned into a quest to squeeze every inch of power using innovative thinking combined with proven theory.

Nelson Racing Engines opened their doors in 1995. 11 years later, owner Tom Nelson creates combinations with the passion he had when building hot rods as a teen for his friends. "That's what keeps us at our best. There is so much to learn. I'm always a student," says Tom. "I eat, sleep, and breathe my profession and want to provide my customers with the best that I can offer. There is nothing more satisfying than getting to know my customer and setting out to achieve his (or her!) goals. It's what gets me up in the morning."

Ultimate Sleeper - NRE 1600hp RX7

Posted Thursday 04-09-2009

At 73 years young, Honest George (as we've come to know him) brought us his Mazda RX7 powered by a single turbocharged 355 chevy. Racking up 17 years of street duty, the v8 powered RX7 was in need of an update as George was becoming bored with it. We decided to answer the request wth our NRE Twin Turbo 427sbc Hot Rod Series Engine. Backed by a Mike's Transmision 400 trans and Moser nodular 35 spline 9-inch rearend, this 1650hp beheamouth was just what George was looking for.

To keep things cool we built two engine radiators - one primary and a smaller secondary radiator running parralel to the ground. We built an air-to-air intercooler, sectioned the bumper to flow cold air to it, and added a large tranny cooler. We also built twin gas tanks - one for 91 octane and one for 116 octane. We set up the fuel injection to run on 91 octane until 2 pounds of boost, then switching to add the 116 octane to compensate for the added boost. To stiffen the chasis, we added a full chromoly cage. The car was rewired with a Ron Francis wiring system to keep things clean and operating.

Keeping the car a sleeper is important to George so we left the 1980's wall tail wing added a few scratchs.The result? Well let's just say if you find yourself next to a blue Rx7 with a V8 rumble and a smiling 73 year old behind the wheel...you may want to reconsider.
