Model Year Summary : In 1989 Mazda gave the second generation RX-7 its only redesign. This redesign was mostly minor cosmetic changes, for instance the 4 rectangular tail lights were replaced with smoked plastic lenses which had round tail lights underneath them. A newer, redesigned front air dam with fog lights was included in the facelift. Also, new and more aerodynamic side view mirrors, which had that hole between the mirror and body, yet had much more beautiful flowing lines and they extended farther from the body than previous models, this also helped cure blind spots in the previous model RX-7's. The spoiler was once again standard on all models. Body trim around the body was now colored the same as the body. The GTU was pushed down and replaced the SE as the base model, and the GTU position in the line-up was taken over by the rare GTUs . The GTUs was identical to the Turbo II but didn't contain the Turbo engine. The GTUs was probably the rarest RX-7 ever made. The 2+2 (back seat) option was now limited to the GXL. The fuel injection system was improved, along with higher compression and lighter rotors which allowed a higher redline of 8000rpm! These subtle changes added 14hp bringing the total up to 160hp. In the Turbo II, changes were also made to the exhaust manifold which increased boost. This raised the horsepower to 200hp. Mazda also made small internal engine improvements, for instance the waste gate became electronically controlled. Outside, new alloys were applied to the coupe models. The non-turbo models had a 15" quasi-five spoke similar to the later 3rd generation RX-7 wheels. The Turbo II and GTUs received a 16" mesh-type wheel. All speedometers reflected the new higher redline and the left cluster of gauges was changed from a 90 degree arch to full circular gauges.
