I have recently converted my truck over to the NV4500. Now that thats out of the way I'm ready to throw the powa at my truck. I'm lookin to be at around 300-350 hp to the ground. I think it'd be better to be closer to the 350 range. I plan to get an HX35 with all the proper housing sizes and whatnot. Im sure the timing will be fiddled with and the proper tuning for the pump. I have a wonderful mechanic to do all that for me. (The guy literally co wrote the book on 1st gens.) And for a little fun fact I'm planning on an intake and I have a 4 inch exhaust waiting to be put on after all of this is completed.

Now the question I have for all of you wonderful minds is what Bosch injectors am I looking for? I want to get the Bosch part numbers so I can start looking for the injectors with my sources to get prices and such. I only wanna get Bosch and completely avoid any aftermarket side name jobbies.

Thanks guys

 

hx35 wont be enough turbo for 350hp, IMO. Why only bosch? there are plenty of good aftermarket injectors.

 

what kinda turbo would you recommend? everyone that ive talked to about this project (cummins employees/retirees that know the 12 valve like the back of their hand) says the hx35 is the way to go. one guy even says the stock turbo is fine and i have no reason to doubt him.

I kinda wanna go Bosch for a few reasons.
A) thats what cummins uses.
B) thats what my sources can very readily get their hands on.

C) Thats what i've been recommended by the said cummins employees/retirees.

 

Depends if you plan on towing or not. I would say go with a fully upgraded hx35 at minimum (60mm compressor wheel) but i really like the he351cw although its better for us manual trans guys. A s300 borg warner (~62mm compressor wheel) would be the next choice.

See here for info:

The hx35 was used on up to 215hp engines, it can be pushed higher but only so far.

The he351cw was used on 325hp dodges and already have a 60mm comp wheel.

 

for 350hp you should be able to spool a 62/65/12 no problem, and for a turbo, they aren't that expensive. If you don't want to fork that much money, put an he351cw on there. Those are my only 2 recommendations for that power level.

for injectors, go with 5x.012 injectors, or even 6x.012 injectors and get them in only a 145* spray angle.

technically, an hx35 should be able to make that much power, but it get's hot fast, and isn't very user friendly power.
