But here's some of what I think I've learned from others:
I don't recall what you've stated about low-side fueling, but I don't think the JMS is going to help much, even with a cam (and larger lobe). If it hasn't already been said (I'm sure it has), you'll need a low side even though the high side is going to move more fuel from the bigger cam. That JMS barely supports FBO ZL1s on E', let alone what you're thinking about doing. You could probably stretch EQ leaner to get a little more out of it, and play with injector timing, but from what I can tell - you'll need a low-side, and that's another grand.
I understand you miss your cam, but were it me, for the power it seems like you're reaching for - I'd consider full intake (BG) and exhaust, Stage X Kong (or equivalent), with a low-side and shoot for E60. Maybe turn the screws on the blower a little more to get more airflow, but I'm not too big a fan of the OEM blower (ported or not) because of the heat. OK - you can fight it with E' and meth, but I'm not sure I like the long-term reliability of a fully-ported blower. Maybe it won't matter if you don't keep the car long. I only know what I'm looking for out of my car, and it's a keeper, so I'm looking at all that stuff when most probably don't have to/want to. You're in CA, so either you're not keeping the car past smog time or you have an alternative.
You can gain engine efficiency with the cam, but that, IMO, just complicates things for what it seems like you're looking for. If you just want a sound of a lumpy cam, you can pretty much make the tune do that on a stock-cam car, lol. I'm sure I'm missing a lot of what you're trying to do, so I'm just another nobody, but you can get pretty far on a stock long-block car with ported-blower with near-full-bolt-ons.
The tank, VCs, coil relocation-type stuff could theoretically wait. Even the gauge, as long as you have a WB. I wouldn't skip on the VVT-delete or oil pump though.
All JMO...
