Planning on upgrading several items soon and I am in need of advice as to what injectors I should use when doing the upgrades.
96 K3500 201K miles
Will get:
>New 2.5" crossover pipe
>New 4" back exhaust with 3" into 4" new down pipe.
>New Turbomaster Pro Turbo
>Heath Diesel Max E Tork kit (includes programed ECM and mechanical Turbo Master)
SS Diesel Supply Cooling upgrade kit (includes dual thermostats with 180 degree stats and upgraded HO water pump with the addition of the larger 21" Duramax fan and brand new clutch)
>New belt and all new hoses etc...
> New Harmonic balancer and pulley
>Boost gauge & Pyrometer gauge
> Cold Air Intake kit (have not decided on which one yet)

So that brings me to the injectors and glow plugs. .......
1. Heath Diesel sells a HO version of Bosch injectors and Bosch Duraterm glow plugs
2. SS Diesel Supply has the "True Marine" injectors listed as made in USA but no brand name listed
3. I also found a set of brand new Stanadyne Injectors (made in Italy)


So with the exhaust upgrades planned and a cold air intake kit which injectors do you recommend and from who? I am fortunate to have the budget to pay for quality injectors and would like to get the most out of my upgrades. Truck is a 5 speed with new clutch.

Thank you,

~GOD BLESS~

Klein marine injectors without a DB4 IP will do you no good talk to whomever you get the ECM from and find out what pop pressure they recommend and get them Bosch injectors set to their recomendation and then I think you will be in high cotton if you ask me.

 

Looks like I need to do some more research and make some phone calls before hand. I am still about 3-4 weeks out from tearing down the truck for the improvements so I'll get what I need dialed in by then. Thank you for your advice about the stock IP not doing anything different with the marine injectors - did not know that.

~GOD BLESS~

Thank you!

Yeah the whole marine injector thing is a big misconception (ADD 40 H.P.) easy as 1 2 3 .

 

Looking at some Bosch Injectors either new ones or for about $10 more a piece new ones. Looking to get either from Heath Diesel or from Central Plains Diesel. I called Bosch directly and they do not make a HO version so will not be going that route. Must be some sort of dealer mod perhaps?
Proper part number from Bosch for a 96 GMC 6.5 for new injectors is #0432217276 BOSCH automotive line is 1-855-267-2483 FYI.

Thank you!

You don't need the SS Diesel cooling upgrade kit on a 96 if it already has a dual stat water crossover,you already have the best pump and stats available from GM.

I would go with a Kennedy Diesel special calibration dfan clutch and the steel blade fan for best results.

 

I have heard that the 1999 1/2 or newer pump is the best available. Order the 2000.

The double stat is a waste of time and money. There are people that have removed them after installing them.

Use a 195 degree single thermostat Stewart/Robert Shaw Thermostats - 306. I have never had to replace one.
