The eaton would be good for low boost performance and streetability, a twin screw is obviously a better unit for big power but no one makes a kit for one anymore.
The "coldside" systems works well on US cars because the weight of the supercharger helps balance out the weight of the driver.
But personally i'd lean towards a hotside system like the jackson racing to make intercooling easier and less complications around the brakes.
Apparently these guys are very helpful when it comes to superchargers:

Actually Bell engineering make a twin screw kit and its hellishly expensive, check their site (4600 USD). Lots of research done to back up that comment obviously
The JR kit is rubbish compared to an MP62, too small, crap pullies and all the hotside idle problems (afm being too far from the throttle body), you will end up replacing half the parts that come with the kit. Whilst there are hotside MP62 kits (stage one tuning) do you really want it cutting out as you approach a set of lights - these are the sorts of probs people are having.
Ok you can intercool it which raises the boost ceiling, but how high is Kijima planning to go with it? As far as bagging the FFS Powercard pro fuel solution (being a piggyback as you describe) maybe you want to read peoples comments on miat.net before jumping to conclusions.
Its a big improvement on the old powercard, everyone that is using the FFS setup seems pretty rapt with it - this includes people with other kits such as stage one that have retrofitted it. Aside from that I'm sure Kijima isn't interested in dropping another $1500 on a haltech on top of any base kit cost (turbo or super). I know I'm not.
Realistically Kijima you have to ask yourself "how much hp do I want and how much do I want to spend?" like Chris I have done quite a bit of research on this, if Tom's kit can deliver between 142 and 168kw at the wheels (Toms own car is 225hp at the wheels off a dyno dynamics at the moment) smoothly and reliably - for a modded car at least - then thats plenty as far as I'm concerned. Even allowing for the climate differences in our part of the globe our numbers won't be far behind (the kit was developed in Arizona on 93 octane fuel - pretty hot there as I understand!).
His kit will absolutely eat a intercooled JR for breakfast based on the above numbers (safetymans old JR SC car was 116kw intercooled). The fifth injector in toms kit gives as much safety as an intercooler at his kits boost level (I think 9 or 10 psi but not sure). The AFR plot of his dynocharts look pretty nice so obviously something is working right with its configuration.
The only thing I would suggest for any FI solution is budget for a better radiator (personally I would risk your clutch if its already been replaced). Also you have to consider whether you are going to get it engineer approved. Personally I am with mine, these two items will add about $1600 to your bill.
Basically I' m just waiting for Tom to answer some q's of mine and I will be ordering as well. The only downer is a wait for the baseline emissions test I am planning on getting (for the engineer), takes a few months. Like Chris happy to share my experiences when I get it sorted out.
Everyone will shout down a super here and tell you how you need to spend 10k on a mania or avo turbo but quite a lot of engineering and thought has gone into the FFS kit. Worth a good look. The clincher for the deal for me is that is has the whine

,it apparently idles and behaves nicely and will do a 14 second quarter when you stomp on it (sounds pretty SP ish to me)
Rant mode off!
