The MHI stage 2 turbo is very underrated compared to MHI 400 ho rating. Here at Fk8td we have seen over 540whp with our fuel system upgrade paired with this turbo. You get OEM reliability and literally bolt right in without even having to swap the Actuator.
This is definitely one of the turbos I’d recommend. I see power all the way out at 7200 rpm before we see it start to fall off. That’s more than I can say for some other drop ins turbos rated at higher power.
29 psi and 500whp is possible on a good set up.
