The owner of this 1977 MGB<\/a> wanted something different. So in the engine bay they swapped a 2.0 L Honda K20 inline-four using custom mounts they made. The Honda motor features stock internals and individual throttle bodies from a Toyota 4A-GE<\/a> using adapters from RZCrew Garage<\/a>. It produces 190 hp (139 kW) and 140 lb-ft (189 Nm) of torque on a Haltech Elite 1500 ECU. The owner also fabricated a custom exhaust header and 3-inch exhaust. Behind the Honda motor is a Toyota W56 five-speed manual transmission and a Ford 8.8-inch rear end narrowed by the owner. The powertrain was not the only thing to get some upgrades. The owner added polyurethane bushings, lowered the front suspension, and converted the braking system using a GM 1-1\/8-inch bore master cylinder. The rear axle retains the Ford disc brakes.<\/p>\n
