Mk1 16v conversation

Hi chaps
Can someone point me in the right direction for a 16v swap thread,
The ones iv looked at are all empty when I open them.
I have a couple of questions about it.
I bought mine already converted years ago, it runs OK, but I don't know how, as it has no plug for the isv and no plug on the microswitch on the inlet manifold and the pipe that comes from something above the oil filter that should go to the airbox is plugged and the pipe just sits by the airbox, I imagine this setup causes you to lose a few ponies.
Also once it warms up it does idle at nearly 2k, stable tho, don't know how it idles at all tbh.
I have a 16v wiring loom in my garage, but the age of it I'm thinking I'd rather have a custom loom made up with just the wiring I need.

i run an abf also kr with no isv on them
