We found this 1969 Lotus Elan S4 listed on Bring a Trailer<\/a> located in San Diego, California. The grey coupe is powered by a 2.5 L Ford Duratec inline-four featuring a bored Focus block with Darton 90 mm MID sleeves, forged 100 mm crankshaft, and Supertech forged pistons. On top is an Ultimate Performance Limited prepped head with oversized valves, upgraded springs, Raceline Limited Duratec-R inlet manifold, and Jenvey throttle bodies. Bisimoto Engineering tuned the motor in 2016 and it produced 251 hp (184 kW) and 206 lb-ft (279 Nm) of torque. Behind the motor is a G-Force T5 five-speed manual transmission and Winters quick-change independent rear end with a Wedgelock differential. The car’s suspension features adjustable coilovers and Wilwood disc brakes on each corner. On the outside you find a widebody covering Panasport C8 wheels (13×7.5, 13×9) with Hoosier A7 tires (225\/45, 255\/40). There is also a custom front air dam, fixed headlights, Vitaloni driver-side mirror, and plexiglass side and rear windows. <\/p>\n
