VVT swap

Hey guys since the budget for my NB6 Projekt gets a massive rise (thanks, new Job) I was planing fixing the rust issues and get some power into the little one.

Cheapest way as I see it would be a 1.9 VVT swap.
So i need the VVT harness, the engine itself, 6 speed trannie, driveshaft (or don’t I?), diff, exhaust and intake system with manifolds and a ME221 ECU. The engine would get a (Stock) rebuild so timing belt, gaskets and so on are also on my list. Overall engine wise it should be around 3500-4500 € as my calculations go.

Did I forget anything essential? If I source all parts it should be all plug&play hopefully.
