The next owner of this car need have no worries about inadequate performance from the 2500 Coupes 'de-toxed' 106bhp US-spec engine. as its impressive list of modifications suggests that this example must be one of the fastest and most highly developed of its kind.
Introduced in 1970, the Triumph-powered 2500 was the first TVR sports car to have an inline six-cylinder engine. This new TVR had been born out of the need for a model that could meet the USA's emissions targets, which was something the existing Ford-powered Tuscan V6 could not do. One of the drawbacks of the 2500 was the fact that, even in the UK, it was only sold with the de-toxed US-specification engine, which produced a relatively modest 106bhp, rather than the fuel-injected 150bhp unit found in the TR5/TR6. The next owner of this car though, need have no worries about inadequate performance as its impressive specification suggests that '22 VXN' must be one of the most highly developed and fastest of its kind.
The car was treated to a 'ground upwards' restoration in 1991 by a TVR specialist, with subsequent improvements and modifications including a full drive train replacement (in October 1993) and a full suspension rebuild. Undertaken in October 1997, the latter included installing Polybushes; powder coating the wishbones, front uprights, brake drums/back-plates springs and ancillaries; a full rebuild of the steering rack and track rod ends with new bushes to column; new wheel bearings throughout; new pivot bars to rear uprights; and drive shaft universal joints replaced. New brake callipers, discs and braided hoses were fitted at the same time, while all five wheels are genuine Minilite alloys (original 'web' wheels available).
Over-bored by 0.020", the engine incorporates Hepolite forged pistons; gas-flowed cylinder head with matched ports and bigger valves; Kent TH5 'fast road' camshaft with matched Aldon distributor; triple Weber 40 DCOE carburettors with K&N filters; and a multi-branch exhaust manifold leading to a JP custom-made stainless steel system. To ensure reliability, the lubrication system has been upgraded with a baffled sump; high-pressure oil pump; spin-on oil filter; and an oil cooler with inline thermostat and high-pressure hoses. A custom-made aluminium radiator complete with sensor-driven electric cooling fan (with manual override) looks after the cooling. Power is delivered to a Triumph gearbox with overdrive on 3rd and 4th gears, reaching the rear wheels via a balanced prop shaft and limited-slip differential. Other noteworthy features include a lightweight bonnet and a fully upholstered and carpeted interior, the latter incorporating high-back bucket seats, three-point quick-release harnesses, and a rear roll cage in MSA-specification tube with secure harness bushes. Accompanying paperwork consists of sundry restoration invoices, a list of early owners, a V5C document, and current MoT.
