Don't get upset if noone answers your question. We're not being rude and someone will answer your question if they know. I don't think you'll find too many experts here on the SR20Di motor. Sorry.

I wouldn't even think about doing this. It's probably the equivalent of replacing the entire front end of the car.

You're looking changing the engine block, gearbox (different ratios), ECU + practically all the sensors, probably the rear-end fuel pump. Bear in mind that the ECU is in the cabin, you'll need to run a new wiring loom through to it, which (without snipping) will probably mean dashboard wiring, central locking wiring, etc, etc.

It'd be quicker and cheaper to buy a car with one already in!

Sorry!
