This 1966 Triumph TR4A was acquired by its previous owner in 1996 and subsequently modified. The car was refinished in Signal Red, and its replacement 2,138cc inline-four was rebuilt and fitted with a Moss supercharger. A Moss aluminum head, a Wizard Cooling radiator, and an aluminum flywheel were also installed along with a stainless-steel exhaust system, and the steering and suspension systems were overhauled. The car also has black leather upholstery on the bucket seats, a color-coordinated soft top and tonneau, and 15″ wire wheels, Wilwood front disc brakes, fiddleback walnut dashboard, wool carpeting, and a Lecarra steering wheel. Acquired by the selling dealer in 2024, this supercharged TR4 is now offered in Oregon with the owner’s manual, service records, spare parts, a car cover, and a clean Washington title.
The TR4A was built from 1965 to 1967 and featured a revised grille and a widened chassis compared with earlier TR4 models. The Giovanni Michelotti-designed body has been repainted Signal Red and features a black convertible soft top, a tonneau cover, a Triplex windshield, a driver-side mirror, a flip-up fuel-filler cap, turn signals on the front fender sides, LED tail lights, and chrome bumpers with overriders. There is a dent on the right-front fender.
The 15″ wire wheels are mounted with 165/80 Nexen SB802 tires. Wilwood front disc brakes mounted on alloy hubs were installed in 2021, at which time the springs, trailing arm brackets, and bushings were replaced. A replacement steering rack and Good Parts CV axle joints have also been fitted, according to the selling dealer.
The cabin houses bucket seats upholstered in black leather with white piping, and interior appointments include a locking glovebox, a cabin heater, seat belts, storage pockets, and a rear parcel shelf.
The Lecarra steering wheel sits ahead of a fiddleback walnut dashboard with Jaeger instrumentation. A Smiths boost-pressure gauge and electric clock have been installed. The five-digit odometer shows 57k miles, though total mileage is unknown.
The 2,138cc inline-four was rebuilt in 2002 with an earlier block and a Moss aluminum head, and the Moss supercharger was installed in 2011. A spin-on oil filter, 45-amp alternator, Mallory distributor, and electric fuel pump with an external Fram filter were also installed, and the aluminum radiator is cooled by a SPAL fan. The hood is supported by struts when open and has a redundant release.
Power is routed to the rear wheels through a four-speed manual transmission. An aluminum flywheel and a stainless-steel exhaust system have been installed.
The commission plate is a replacement, and the removed tag is included in the sale and presented in the gallery below.
Records are included in the sale along with jacking equipment, a car cover, and a “big-boost” kit that includes a bigger pulley for the supercharger and a longer belt.
