I'm not really going to argue here, both turbos cost a lot of money, and I think there is a correct application for them all. But I've never seen a single-scroll turbo on a stock STI spool dang near like the stock turbo and be capable of 500+whp. I know I know dyno's don't show transient response, but I'm pretty sure the power curves don't lie.

I do believe the external gate housings are still investment cast across the EFR line. They only had problems investment casting the more complex internal gate housings.
