The 820 Turbo used the M16 engine with a water-cooled Garrett T25 turbocharger and intercooler, developed by Tickford.
The new "T" series engine had new inlet and exhaust manifolding, valve springs, exhaust valves, fuel pump and injectors, spark plugs and specially designed Mahle pistons were fitted, and, significantly, all 820 Turbos had a new exhaust system with a three way closed loop catalytic convertor.
The 820 Turbo’s power output of 180bhp at 6100rpm had an impressive torque curve, a description scarcely appropriate, so linear was the delivery of the 159lb/ft maximum figure from 2500 to 6500rpm. This new-found torque turned an engine which always had to be worked hard into an effortless and flexible ground-coverer, which paradoxically was a far more willing revver than the normally-aspirated version, with the side-benefit of the twin cam’s high-end harshness being largely muffled by the turbocharger and new exhaust The turbocharged engine’s forté, in the 820 Rovers, was its prodigious fourth gear acceleration capability, with sub-seven second figures for the 30-50mph and 50-70mph increments.
It was bloody quick, hitting a ton in 3rd easily in the 220 Turbo.
