As I'm sure many of you also know, the resistor mod seems to be a fairly popular and cheap modification for the 1KZ, especially in our wagons as folks complain about the power.
I have seen many people *claim* that it lowers EGTs. But does anyone have real world experience with this that has verified this truly does reduce EGTs? I have been hesitant to do this mod (my headgasket went right after I bought mine, so I replaced the head and turbo while I was at it and now I'm paranoid about it happening again), but if it truly does reduce EGTs it could be a worth while mod.
I understand it doesn't change the fuel pressure, just the timing for the common resistor mod. So, it's not increasing fuel and combustion, thus more heat that way - I am tracking there. But how would adjusting the timing cause for better out-flow of gasses when the change in timing is causing higher responsiveness?
