Hi.
Currently building a new engine for my hj60 2h Sahara. The one in it is sick.
The cam was worn, replaced it with a new 12ht one.
Gt 3582 turbo a/r 0.63, old one was same but a/r 0.7
Everything else is 2h.
According to the manual 12ht injector timing is a few degrees more advanced than the 2h.
Because of the addition of cam & turbo I am unsure of the best setting to go with, or even something in between.
Still Googleing possibilities but all input and opinions will be helpful.
Thanks.
