Just looking into it really, but anyone know if its a feasible option? V5 engines go pretty cheaply, as far as I know bolt onto existing gearboxes. Larger displacement etc. obviously custom manifolds need to be made but not really seen much info in the net. Just wondering how CR can be lowered, whether a stock ecu v5 ecu can be made to run boost? Appreciate it won't have n75 for boost control but if you run a MBC whether fuelling will still work.
