Hi, I am new to this forum so this might seem like a stupid question but I have tried the search function but to no avail.

At the moment I am building a 1992 1600cc SOHC D16Z6 EG5 for road/drag use. The car was bought with some rear end damage and due to the fact that it has been sitting outside, stationary, for the last 2 years it has rusted really badly round the rear arches and rear sill ends. My every day car is a 1993 1500cc SOHC D15B2 EG4 which has a great shell but now has a wornout engine and gearbox.

So my question is how easy would it be to swap the D16 engine into my D15 car in relation to engine wiring? Do I have to swap over the whole wiring loom & ECU or is there anything else that can be done?
