Im not an expert but...
you just need the engine and loom and it should all just plug in/bolt on.
I'm not 100% sure but you might need a loom from the same series of r33.
If you have a series 2 r33, you probably want a series 2 r33 engine and loom
if you have a series 1 r33, you probably want a series 1 r33 engine and loom
you will also obviously need an rb25de r33 ecu
having said that, adapting the loom to fit shouldnt be that difficult if youre handy with a soldering iron
However, in all honesty...
You would be better off selling the RB20E R33 and buying an RB25DE R33
The amount you would save in petrol would actually make it a pretty financially sound choice.
