Default engine break in?
Should I take it easy or push it? The new built engine with the new turbo setup, clutch, built head, and tons of money and freaking time is almost complete but need to know how I should break it in or if I should just go for it. TIA

Default Stay low on boost, or youll wash the hone out. Don't be afraid to wind it out a little bit, but
don't stay high in revs very long. Moderate engine braking is good too.

Never keep the engine at the same rpm or load for too long.

Default I dont agree with this, you want boost to wear the rings in all sit., friction erases hone
This is how its supposed to work. I didnt do 33lbs on breakin, but I sure hit 26-28 a lot and stayed there quite a bit. I have put approx 13k miles on car since initial build, and it is still very good. Tip was good on engine brakeing tho, I fully agree with that. Hit every RPM.

Race engine break-in is not applicable.
