1989 and 1990 models are powered by a naturally aspirated , SOHC KA24E engine with 3 valves per cylinder (instead of the turbo-charged and intercooled 1.8-liter DOHC CA18DET offered in Japan and Europe in the 180SX and Silvia). Four-wheel disc brakes were standard, with antilock brakes available as an option on the SE. Both models were offered with either a 4-speed automatic or 5-speed manual transmission. "Coupes" offered a Heads-up display (HUD) with a digital speedometer as part of the optional Power Convenience Group.
