1.3 engine to mk1 1.8gti shopping list help

Ok i was originally planning to get a 16v conversion done but with time and money running out, I'm keen to put a 1.8gti enginw in and upgrade to a 16v in the future.

so currently I have a 1.3 driver and im wondering what I need for the conversion

I have so far..
gti fuel tank and fuel pump
100mm drive shafts and hubs

So obviously I need an engine with cabrio gearbox to suit the shafts, and a wiring loom.

What else do I need to get to conplete the conversion?
