A simple upgrade to a Evo3 16g is what I would do in all honesty. If you do want to go 'big-ish' I'd go with a nice solid FP setup and their HTA 3076. Specifically note the 'HTA' in 'HTA3076' because the regular 3076 is a little bit of a dog. The HTA76 compressor wheel will produce similar results to the reviews of FP's Evo RED I've posted here. You'll end up spending a little more, but I think you'll have a freaking sweet bolt-on setup that should make loads of power and be very very responsive for daily driving, and be really really reliable to boot.
On E85 it should kick some serious ass.
Side note: FP's 3052 and 3065 are old-ish designs. The HTA3076, HTA3582 and HTA3586 are the new way to go.

After saying all that, I would be hard pressed to not at least look at a 20g...looks like FP happens to have a nice bolt-on internal gate (economic but fine if you're going E85) 20G-6SL2 for $1150...that's a pretty damn good deal.
