450hp LS-Swapped 1985 Mazda RX-7

Gaven Holley's 1985 Mazda RX-7 combines Japanese styling with American muscle, thanks to a 6.0-liter LQ4 engine swap making about 450hp. Backed by a Tremec T-56 six-speed manual transmission, this build features a Holley Hi-Ram intake, paired with dual 450 CFM carburetors, offering significant power boost from its original rotary engine. Suspension upgrades include BC coilovers and Racing Beat sway bars, enhancing its stance and handling. This head-turning RX-7 has proved itself in autocross and burnout contests, maintaining reliability and fun.
