Carbs, fuel pump, pressure regulator, inlet manni, new cables and fuel pipes. Pretty much it!
Look on clubgti, there are a few how to's on there.

I think most (if not all) bike carbs need 3bar fuel pressure, I know that k-jet uses 5bar so the original pump would kill the carbs.
You can use the bike fuel pump (as I am doing with my carbs) which means you wont need a pressure reg.
The rest of the kit is easy, the hardest bit is getting a inlet. It can be custom made (which costs £150+) or as i'm doing using a chopped down inlet with samco hoses to join the inlet with the carbs, but i'm using a 16v engine so the inlet can be used like that, no idea about the inlet on your engine?
I also forgot to mention that the carbs will need new main jets and setting up properly!

Lee mate, some bike carbs need to positioned exactlly as they were on the bike in terms of angles, otherwise they wont work

Personally I wouldn't bother with bike carbs. Save up for a set of DCOE 40s.
They wouldn't thank you much for 3 bar of fuel pressure either! More like 1-2 psi.

It's your money, but IMO it's a waste of time on a 1.6 8v. Carbs with no manifold cooling, sitting above a hot exhaust - recipe for an unreliable car. If you want to fit bike carbs, buy a 16v lump first.
If you really want to keep the current engine, Spend your money on a flowed cylinder head and a cam, or just an injection head, if the budget won't stretch to a flowed one. Get the head skimmed to lift the compression ratio up from the wheezy 9:1 to about 10 or more, and you'll see a real power and torque increase, even on a weber 32/34. You'd still be better off with a 1.8 though ;)
