This 1973 MGC GTS tribute race car is for sale on Bring A Trailer located in Norwood, Massachusetts. The car is built on a 1973 MGB GT body and chassis for HPDE, time attack, and other track events.
Under the hood sits a twin-turbo 2.5 L 1JZ inline-six taken from a 1990 JDM Supra. The engine sits much further back than the factory engine location thanks to moving the firewall back 10 inches. The engine produces a conservative 255 horsepower and 255 lb-ft of torque using an APEX ECU and custom wiring harness.
The engine being pushed back required a custom transmission tunnel to hold the Toyota R154 five-speed manual transmission. From there power goes through a custom driveshaft to a shortened Ford 8.8 rear end with carbon limited slip diff and 4.10 gears.
The MGB rides on a FASTCAR double wishbone independent front suspension with rack and pinion steering. The basic geometry was designed after a BMW E36 M3. The rear is a Levy Racing Watts link designed off a Mustang. Penske racing shocks are found on all four corners.
Brakes were upgraded to Wilwood 11.75″ discs and six-piston calipers in front and Mustang GT 10″ brakes in the rear.
