    Tuned it over to 6NZ from MBN. I think I blew a ring out. Have some coolant in oil. Any tips on new rings for longevity over stock? Also, head studs? My EGTs are too high for me 1000 egt every now and again. I’m looking to get it down to 850. Any injectors cool me down a bit? Don’t want to add but 100hp max.

    More injector will raise egt. More turbo cfm will lower it.
