Lot 19: Triumph TR4

Code named 'Zest', the TR4 was introduced in 1961 as a replacement for the TR3A. Though it was based on the chassis and drivetrain of its much-loved predecessor it cut a far more modern dash, thanks to an all new Michelotti-styled body. Power was provided by Triumph's proven OHV four-cylinder engine. The capacity was, however, increased to 2138cc. Other mechanical updates included a wider track front and rear, rack and pinion steering and an all-synchromesh gearbox. The optional overdrive was now made to operate on second and third gears as well as top - the result was effectively a close-ratio box with seven speeds.

The 1964 example offered was repatriated from California before being professionally restored, converted to right-hand drive and race prepared at a cost of more than �30,000. The comprehensive specification includes: lightened body with fibreglass wings, bonnet and boot; Perspex windows; detachable fiberglass hardtop; full rollcage; bucket seats; full harnesses; fire extinguisher; electrical cut-off switches and small-rimmed Mountney steering wheel. The 2289cc engine was overhauled by TR Enterprises of Mansfield in 2007 and has: a racing camshaft; uprated followers; twin Webers; Facet fuel pump; in-line fuel regulator; lightened flywheel and upgraded valve springs. Also: uprated cooling system, oil cooler; Kenlowe fan; lightweight alternator and starter; electronic rev-counter and large bore exhaust. The engine is mated to a race-spec gearbox. The brakes use magnesium drums at the rear, and the TR4 rides on Minilite-style wheels shod with Yokohama tyres (a spare set, is available separately). This attractive Triumph has been garaged in the winter and, though not raced in the five-and-a-half years of present ownership, has completed three track days and the occasional road rally. Said to be perfectly road-usable, it comes complete with extensive pictorial history file detailing the restoration and race preparation.
