Out of what I wrote does not answer your question?

As I stated if you have a donor car then it's not to bad as you can simply swap the parts over, you will need the exhaust from the 1800 car to fit to the 1600 car, and the suspension etc, like I say it's been covered on here plenty of times before so if you do a search there are threads where people who have actually looked into it in depth and have listed everything you will need to do.
