Hi - I’m new to the forum, so I’m guessing this will have been covered extensively before. Just bought a 1990 Defender fresh out if a ground-up restoration. Wanting to take out the TDI and install the 3.5 V8 which is in my garage once I’ve fitted a new water pump, and changed the SU’s for a new inlet manifold and 500CFM Weber. Is this feasible or a world of pain? Any advice gratefully received
