I have recenlty taken out a standard VX engine from my 7 HPC. Its is fuel injected, has all the Caterham bits, sump, alternator , starter motor, exhaust system and is complete with Motronic ecu. Its ready to go with 40,000 miles under its belt. Its not 200 bhp as you requested but a reliable 165bhp with 165 ft/lbs of torque. Pulls like a train and a good starting point if you want more power.
Blat mail me if interested
