That fuel rail mounting looks a little rough, I've got some fuel rails I made that will mount a bit nicer if you are interested. Made for the same injectors, I'm running MSD 50lbs ATM and tossing in some Precision 1000cc's once I install the Isis manifold. I've got one of them mocked up with an Isis manifold right now if you want to see. Here is the link, the rails are the ones pictured on the carbon hood.

I might be going to be going 90mm 2.2 very soon as well, I'm interested to know what results you get. I gotta tear the motor down here soon to see what damage we have......
