I shall reveal all later but I have the good fortune to acquire a lovely GTL engine in amazing condition. Reading past threads about the fabled Hennessy Hot up kit I'm interested in doing same/similar . I don't want to go completely mad because the vague and distant target for said engine is a Renault 4 for my son. Made to look similar to the East Africa Rally entry. He will still be a young driver so a proper HOT PIRI PIRI engine would be impossible insurance money. Plan is same starting point as WOMBLE (a GTL) so I don't have to declare a massive engine change or heavy duty modification. Looking at an R5 manifold carb pump etc - what would you guys recommend ?
