upgrading turbos

[770JOHNNYW]

Looking for some input I have a lb7 with s300 60 mm with t4 housing over a gt47. What can be done without buying different chargers. Ie. Billet wheels different housings etc. Thought about sending them both out to be rebuilt and billet wheels in both. Is that a bad idea?

Are you just looking for more total power? Do you know how much power you're making now?

Probably mid 900s I would say maybe more. I just wanna see what's out there mainly for the gt47.

88 is about the biggest we can do in the 47 frame, we have done a 91mm but they are ungodly expensive. i know the precision billet wheel will make more power than a cast garrett wheel though.
