The factory turbo on the EJ25 is a journal-bearing unit that is fine at stock power but becomes the limiting factor for spool and reliability once you push more boost. The P660 ball bearing turbo upgrade bolts on directly and delivers faster spool, more power, and better long-term reliability.
Features:
Supports up to 600HP+
Advanced CAD designed in the USA
Billet wheel & dual ball bearing
Comp wheel with 9 billet wheel blades (vs. OEM 44mm)
