I agree with all of your other points except for this one. Some of the most reliable highest HP FI'd vehicles to date have been turbo'd V6's. The V configuration lends itself much better to overall engine stability and is a much more balanced design to boot. The Supra's FI'd V6 is legendary for the amount of power it produces reliably as but one example. They aren't as widely used because they are much more expensive to produce therefore we only see turbo'd V6's in relatively expensive vehicles, but power-wise they are hard to beat. Not saying that I4's don't lend themselves well to FI, they do, and they are less expensive to produce, but IMHO not more reliable per se. There are daily driven 800+rwhp Supras (even 1000+rwhp) and daily driven built 600+rwhp 300/350Z's out there in spades compared to daily driven I4's that you'll find at those power levels.
