Despite being a replica, the car externally is as original as you could get it, made totally from scratch however, the gearbox is a ZF gearbox. The makers of this beast are RM Wilson Engineering of Leicestershire, England (www.rmwilsonengineering.co.uk) who have been in the trade for over 45 years. They have made their own fuel injection system for it and also made their own dry sump for it. The engine is a 360 GT engine and produces more bhp than the original. I hope this helps give you a little more of an insight!
