Pretty much all the induction and exhaust components, and that's before you start looking at electrics and internal components. I'd go for the swap.

As already said, but the key internal difference is that the 190 engine has higher lift camshafts which supposedly contribute to the higher performance. Unless you're doing a belt/water pump overhaul at the same time, swapping the whole engine is the obvious route. However, don't forget that the 190 also has larger front brakes.......

Hi Crispin,

I've never heard that before, can I ask what your source is? RAVE doesn't mention it.

From memory, the 190 used a higher lift exhaust cam - interestingly enough the 180 Sports Auto has it too.

I can sort out the immobiliser for you without any problem Kev, much easier than swapping engines and stuff

Where did you see that Mat? The camshaft timing is certainly different on the 190 but there’s no mention of lift in RAVE.

Yep, cam timing specs are in there, both cams are different. Don't have access now to dig it out.
