After Carroll helped Dodge massage their 2.2 cars, he wanted a more aggressive, performance oriented vehicle. He bought the last 500 black 1986 GLH Turbos and had them shipped to his plant in Whittier, California. This is where the 146HP GLH made its transformation into a GLHS! Shelby upgraded with an air-to-air intercooler, different turbo and special intake manifold, larger injectors and throttle body. This allowed a bump in boost from 9-psi to 12-psi. The result was 175HP and 175lb-ft of torque.
The suspension was upgraded with Koni adjustable struts/shocks and Carroll added more negative front camber and a bit more toe-in in the rear. The tires were upsized to 205/50VR-15 Goodyear Gatorbacks, mounted on Shelby Centurion aluminum wheels.
The inside received a sticker overlay on the unpegged speedometer that gave it a readout to 135 MPH and a leather-wrapped steering wheel and shift knob. The last interior change was the replacement of the plastic Omni badge with the numbered Shelby Automobile badge.
Performance: Quarter mile times between 14.8 and 15.3, 0-60 in the 6.5 second range and a top speed of 130 MPH. Brings a new meaning to the term "grocery getter."
