Trackspec Autosports<\/a> is a company in San Francisco, California specializing in Lotus, BMW, Porsche, Honda S2000, and NSX track performance. The company has built several cars for the track including a special Lotus Exige<\/a> with a 2.4 L Honda K24A inline-four. Trackspec Autosports swapped the motor using Innovative mounts<\/a> and upgraded the motor with a K20 oil pump, Unit 2 Fabrication baffled oil pan, and Hytech 4-2-1 exhaust header. On top sits a 4Piston Racing TSX CNC ported head with 4Piston Racing RR3 camshafts, Supertech valve springs and retainers, and Ferrea valves. On the side is a RBC intake manifold with an Acura ZDX throttle body and Acura RDX 410 cc injectors. Everything is controlled by an Emtron KV8 ECU and custom wiring harness<\/a>. The K24 produces 249 hp (185 kW) and 179 lb-ft (242 Nm) of torque. The drivetrain uses an Exedy Stage 2 4-puck clutch to a DC5 Integra Type R transmission with a 4.7 ratio, limited-slip differential, and Innovative axles. Trackspec Autosports upgraded the car’s suspension with JRZ RS Pro 3 coilovers and AP Pro 5000R four-piston front brakes.
