This Jaguar XJ6 Series 1 originally came with either a 2.8 L or 4.2 L XK inline-six. KC Performance<\/a> was tasked with swapping a 4.0 L AJ16<\/a> inline-six from a Jaguar XJS<\/a> or XJ6. The more modern motor benefits from drive-by-wire throttle body, upgraded radiator, and standalone Ecumaster Black ECU. Behind the motor is ZF 4HP four-speed<\/a> automatic transmission controlled by a HTG Tuning ECU. KC Performance improved the handling with upgraded front brakes calipers and vented rotors. They completed the appearance with black bumpers, grill, trim and a set of 18-inch wheels.<\/p>\n
