Hi, I've actually see one of these... they are quite rare to find, and to be honest you'll probably struggle for parts if you need them.
The ECU is completey different, I dont even think you could splice one in to work.
The turbo flange is different too, the 2.0 Evo uses a TD05H turbo. From what i can remember the 1.8 used a similar one but smaller and had different flanges on both sides of the turbo. You could possibly make one fit if you changed the Manifold for an EVO one, no garantees this would fit on your block mind. Or get a an adapter made up. Either way the down pipe for the exhaust would also have to be changed.
In a nut shell mate, you might have saved a few quid on insurance, but it'll cost ya getting anthing mire than 240bhp out of it.
