Does anyone make a kit that isn't over turbo'd for 91 octane?

I get that you want to broaden the torque curve, but 91 limits more of your low end than top end.

Whatever turbo is used is going to be artificially limited, via a boost controller, at one end or the other. I'd rather a turbo that has better transient response while still running in its efficiency island, than a turbo that I can tell my friends could make 500hp. The WRX turbo is a good idea, I'll have to look up which turbo it runs.

09 to 14 WRX runs a VF52 turbo if I'm not mistaken. 15+ runs a Garrett MGT2259S You could hit up ForcedPerformance to see if they can adapt one to a flange you need and buy the other pieces as needed. JDL makes a t2 and a T3 hot parts kit all said and done for about $1,700 (depending on your options) and you can have an intercooler pieced together for you easily enough.

I'd be willing to bet a small efr or gtx will spool as well as the Garrett in the 15+

So many turbos would be better suited than what OP is suggesting, but they won't listen to reason. Efr would be the way to go I think, and full race even makes a twin scroll manifold for them..
