6G74 ralliart

From Mitsipedia

The Ralliart 6G74 was a tuned version of the revised 6G74 to power Mitsubishi's 180 kW TJ Series II Ralliart Magna. To increase power over the base 3.5 Litre V6 it employed a higher compression ratio (9.4:1 up from 9.0:1), higher lift camshaft, strengthened valve springs, more efficient cylinder heads, improved exhaust flow, recalibrated ECU and headers.

The engine was short-lived, being built less than 12 months.
