TVR TURBO

TVR made this 230bhp turbocharged (by Broadspeed) V6 engine installation on all their current models, from late 1975, but few were sold. Top speed of at least 140mph,  0-60mph in 5.8sec but 19mpg made it a fierce, expensive toy to have. Higher overall gearing than normally-aspirated cars and fatter tyres, but no chassis, and especially, no braking changes. Rare, desirable and brutal!
