I got a type 4 in my crosser......the extra horses are a big bonus... but when things go wrong the bills are bigger......cylinderheads /heatexchangers almost double the price of type 1
as for the swap over parts needed..the hangers for the engine brace bar-crosser part only
gearbox ok-can change input shaft.
Also not very economical on fuel for me
i agree with price of parts! i've got 2L in my corssover, and once body is sorted on resto i will be having the engine rebuilt. even pistons and cylinders are double not to mention is you require to change your crank at any point.
i used to manage around 24-26mph on a motorway run from south wales to licestershire and the carbs werent perfectly set up.
if you aren't after spending alot of money i think you will be best at looking at trying to get the best out of what you have. another words look at potential free hp from bolt-ons.
