upgrading to 2056, Need help sorting out FI Options

[jesse7flying]

I've tried doing some research so I wouldn't ask too many stupid questions, but here goes. I acquired a 1.8L engine that had dropped a valve. My plan is to upgrade the guts to make a 2056 out of it. I've bought a 2.0L crank and rods (thks Dominic) to put in the "new" engine as recommended by Jake Raby in some older posts. The thing Raby does not address (unless I missed it, very possible) is what do I do about a cam? It seems like Raby's default position is to use carbs, but I would like to go with the FI system. Does that mean that I need to source a FI system from a 2.0L motor including the MPS, AFR, ECU, injectors, etc, or is anything off a 1.7 or 1.8L motor usable in this case? Once I have a list of items to buy, I will place a WTB ad in the forum, but any suggestions to point me in the right direction would be very much appreciated.
Regards--Jesse
BTW, I did not mention that I'm trying to do this upgrade as cheaply as I can, but I don't want to be stupid about it, lol.

Should have mentioned that the 1.8 came with no FI at all. Sounds like folks like the L-jet system. Will a stock 2.0L cam work for this set up? I understand that if I use the existing 1.8 heads with the stock valves, I can get a better low end response at the cost of high RPM performance and I'm OK with that if that will keep my costs down. I can see 96mm P/C in my future. Keep 'em coming guys. Thx.
