I was told to go 7163 by fullrace if im limited to pump fuel ....
But that 2.5inch intake turns me off soooo bad
The 7670 looks 1000x time better with uts 3.5inch intake

It's pretty crazy how close all the EFR's are in spool. The 7670 is a significant step up in wheel size and turbine flow, and definitely won't have the serious low RPM grunt of the 7163. If you plan on running large cams or nitrous for spool, I'd run the 7670 to take advantage of the top end flow, but otherwise I'd pick the 7163 every time.
