Yes, I am running stock factory injectors, and I didn't think it possible to boost over 40 psi in my current configuration. I was planning on installing 75 - 100 hp injectors, at a later date, but now I just don't know if I should. I've looked at head bolt studs and gaskets and most high performance parts are listed at a max boost of 60 psi. If I'm hitting 45 psi now what will 75 - 100 hp injectors take it up too???
Maybe I will contact Jeremy at Quadzilla and get his take on it. On a different note... Will 75 - 100 hp injectors really increase fuel mileage??? Common sense dictates that increasing fuel volume / fuel flow will also increase fuel burn resulting in less mpg. So, all BS aside, has anyone actually gained fuel mileage with larger injectors, that is as long as they drive sanely??? |

I had a basically stock 12v small mods on it such as fp and intake filter and i was able to hit 42psi with the stock turbo, but yeah i would do some tuning and get the boost psi down, or either get headstuds

I went through 2 seasons of racing making 85psi with 0 issues. yes bigger injectors can increase your fuel mileage if you use the skinny pedal properly. |
By O-ringing the head I assume you are referring to head gaskets such as the Fire Ring, correct???
Please educate me regarding O-ringing the head. Will it be necessary to have any machine work done to the head prior to O-ringing??? Or is it just a matter of installing new gaskets??? What brand of studs do you recommend; ARP, ATS, or what??? And what about injectors... any recommendations there as well??? Can you tell that I'm new at the "Diesel Performance Parts" game??? Thanks again for the comments and insights. |

o-ring is a grove only cut in the head. they work and are less of a mess than fire rings.
