Stock Frame turbo upgrade wanted!!

[GGcloudIX]

ya i know a lot of guys swear by MAPs EF series.... but I also know a lot of guys who swear by the FP lineup..... i'm going to be talking to the guy tomorrow about his red, so i should know within a couple days. If that falls through, guess I'm going EF!

I think an EF3 is a little big for my goals ( roughly 450 corrected whp on DBs dyno on e85 with good bolt ons and e85) I want a turbo that will make my power goal but not be maxed out doing it, so that way i will have room to grow in the future.... so which EF turbo would be my best option? EF2?
