Building a 6NZ..Any suggestions?

This really depends on your Hp goals and what you would consider over doing it. 700 Hp, 750Hp, 800, Hp 850 Hp 1000 Hp?????????

 

Get ahold of Mr. Haney....he'll steer you in the right direction....if you got the time take the block and crank in and have a machine shop check um out...got mine decked and all liners measured. 005....should b firing her up late tonight or hopefully tomarow .....marine cam, 58s stillgotta get the ecm to Mr. Haney and his turbo....my first kitty cat.....swaped out the N14.......been a good project..

 

Guess I need to b a little quicker typing .....Kurt u beat me 2 it...

 

I just rebuilt one, dyno'd 700hp and 2200ft/lbs at the rear wheels, stock turbo, dura-lite cac, fuel temp chip, flowed fuel pump, took out all the hard 90* fittings, STOCK 550 FLASH, pdi manifold, custom exhaust manifold stud kit (never break a stud again!), and changed fls/fts to something I know that works. I think where a bit of the power came from was the custom injectors I had built and balanced to run within 2.5% of each other, just from running 5232 codes on the dyno to balanced codes it made another 100ft/lbs more torque. The shop that built mine call them 170 lb/hr injectors, hardly any smoke. Stockers run at 145-155 lb/hr, and run with 15% of each other. Truck is a blast to drive, and is used to move heavy equiptment, hills with a heavy load dont see egt's over 800* and boost over 38psi.

 

What kind of horsepower could one expect from a 6NZ with a 800hp marine cam, PDI stage 1 tune, PDI manifold, and BW turbo. Also PDI injectors although I have no idea what trim codes, would imagine that depends on what you want out of the application. Would this build put 750 to the wheels? Is 750hp streetable in the same sense as 550? What I mean by that last question is I have read how much attention and focus it takes to drive a 1000+ hp motor in a work truck to keep from tearing up the driveline. 550 or 750 is obviously a lot more forgiving.. 1000+ hp making you feel stressed out just from staying so focused on every shift and move... It takes concentration in a 550 as well but not anywhere near what you've described in a post on here somewhere about driving your truck Kurt..

 

Is pdi still selling injectors? I heard they stopped because they werent too great, lots of failed injectors. Far Call is of of few I know of that can sell you a awesome set of balanced injectors. I had mine built here in Canada. My stock tuned unit is driven daily by company drivers in northern alberta on and off highway moving HEAVY loads and its solid. I think dyno'ing would be a good investment to learn what your engine would do under load as to what temps it'll hit, and give you braggin rights.

 

Already been said, Mr. Haney!

Ashman, tell us more about exhaust stud kit?

 

I'll take pics and post, this kit will impress all of you. They were custom built for this application and to date have not seen one boken stud on the many that have installed
