1997 Acura SLX gets 350 actual Acura horsepower for Radwood

For the Radwood Orange County, Calif., car show, a show themed around 1980s and 1990s cars, Acura is bringing a variety of its original models including a 1991 NSX and a 1986 Integra. The company is also bringing something obscure, a 1997 Acura SLX, the brand’s first SUV, offered from model years 1996 to 1999. In some ways, it’s something Acura might not want to highlight, since it’s really a rebadged Isuzu Trooper, just as the original Honda Passport was a rebadged Isuzu Rodeo. But this SLX is special; it has real Acura power under the hood.

The project was led by Acura engineers and Pikes Peak racing drivers James Robinson, Paul Hubers and Jordan Guitar. The team pulled out the original naturally aspirated 3.2-liter V6 that made just 190 horsepower and 188 pound-feet of torque, and dropped in a turbocharged 2.0-liter inline-four from a new Acura RDX. That engine also received a new intake, exhaust, turbo and ECU tune, which brought power up to an estimated 350 horsepower and 340 pound-feet of torque, similar to the Graham Rahal Performance RDX. Not only that, but the old-school four-wheel-drive system and live rear axle were dropped in favor of the RDX’s indpendent suspension and torque vectoring “Super Handling All-Wheel Drive.” “Dropped in” is a mischaracterization, though, as Acura had to weld new subframes front and rear to the existing frame to get the transverse engine and modern suspension to fit.

Acura was careful to keep the SLX looking as close to the original as possible. On the outside, Acura repainted the SLX in a modern red paint available on the RDX, but retained the champagne lower moldings. The stock wheels were replaced with 17-inch Fifteen52 wheels, but they have a very similar design and finish to the original wheels. A hard-shell spare tire cover was added, and a simple “SH-AWD” badge on the back is the only hint at what’s under the body. Inside, the upholstery was redone in a gray “gathered” leather like you would have seen when it was new. A bit of gray wood trim updates the interior slightly. The RDX’s push-button starter and shifter buttons have been added to the center console, shift paddles behind the original steering wheel, and an aftermarket instrument cluster mounted to the steering column.
