HUMMIN' CUMMINS

A 1,000-HP DIESEL IN A MILITARY WRAPPER

- JASON SANDS

Steve Ortner, of Belleville, Michigan always wanted a Hummer. When he did finally get the chance to buy a ‘94 Civilian-spec Hummer H1 he was quite overjoyed. But, there was a problem. “The Hummer had a naturally-aspirated 6.2L engine in it, and it was so, so slow.” says Steve. “There were times on hills you didn’t think it would make it up to the speed limit!” laughs Steve. For sure he had the vehicle he’d always wanted, but it was powered by the wrong engine.

Performing a Cummins swap is hard enough, but Steve went the extra mile and built his 5.9L 12-valve for monster power. The engine makes an estimated 1,000 hp and 1,700 lb-ft of torque through a GM 4L80E to the Hummer’s all-wheel-drive system.
