I may be the guy to try this. I have alot of spares and I will not cry if something goes wrong. I have that turbo off the 7.8 New Holland. It is fresh and healthy. It is a To4e. That 7.8 made around 300hp, according to Ford. I have a few CACs to work with. I am thinking of running one of my offroad bumpers with a grill gaurd, deleting the grill, then installing the CAC behind the gaurd. I have a close friend with a Masterbender 3000 exhaust tubing bender in his shop. I am doing a custom freeflowing setup or nothin'.

I am thinking I should punch out my 6.9 block with some new, low compression pistons. But I want to find a set of good used turbo rods before I order the slugs. Who has a set of turbo rods? :angel:

I also will have to figure out if there is a big block H-beam rod that could be adapted to work in a 6.9. The rotating assembly is freaking heavy in these things. Parasitic losses in this engine are probably over 140 hp at 3000 rpm in an IDI. Anything you do to lighten the rods/pistons will show an increase in power.

When you say $2000, are you talking about just for the pump or for the related components to support the big fat fuel flow? Which pump would be most cost effective to Super Moose? Do you see any issues with breaking the pump shaft?

thanks for all the help. a powerstroke is not an option for me because when i bought this truck i only paid 1200 for it i could not buy half a powerstroke with that. I have 2500 to spend on mods and as soon as I sell some of my other toys ill have more. i did not know that you can chip an idi.

To be honest those numbers aren't that unreasonable just like Mel said.

http://www.thedieselstop.com/forums/f30/nw-dyno-days-2011-results-283880/

Here is a guy that made 296 hp and 487 lb-ft with not that many mods above what some others on here have. I believe the biggie in what he made was his 99 PSD turbo he used and the propane.

Also check out NMB2"s dyno thread on here. It is a somewhat controversial tread on here but I believe he made the power that he showed. He had upgraded turbo up pipes which I believe also help.

And then Heath made pretty good numbers also. His best dyno is 202/461. I believe if he upgraded his turbo and was a lil closer to 20 psi of boost that he would easily be at 250/500.

Also Hypermax sells a C ring so your boost will hold at 20+ psi and there is also propane or water/methanol on top of that. Also type4 sells a pretty good cam that I plan on eventually buying too. So, imho those numbers are not that hard to get. You just have to do a lil more than you have to with newer diesels but thats always the fun part to me. :thumbsup:

Also what year is your truck and what engine do you have. We need details. Cus if you have $2500 you could get a used turbo, a Moose pump, and whatever other mods you decided you wanted and be making some decent power. Don't let anyone talk you out of anything these truck just need a lil more TLC. Lol

You can't. He was making a joke. Mel has a potato chip encased in plastic that he shows off to guys asking what chip his truck has.
The IDI is mechanically injected, there are no electronics controlling the injection process for a chip to do anything with.

I have 1994 7.3 turbo with 135.*** miles on rebuild and 217.*** miles on truck
if you already have a turbo, best thing to do is get a hopped up rebuilt pump from Mel/Angem or Ken(DPS) and a good set of new or rebuilt injectors. if your turbo has not had the aftermarket outlet and downpipe done, do it. addition of propane is not a bad idea either. all these items may not get you to 300hp but you will get close and stay with a reliable truck. You can get wild with a larger turbo like a HX35 and put on a external wastegate, but that requires fab work you may not have time for. As far as who to go with on the pump, do your own research to see who you can live with on both performance offering and customer service.

I would recommend a torque cam for towing that big trailer. Torque is more important than HP.

Chip it. ...

Just kidding. Why do you want/need 300? A daily driver would be fine stock, or even just adding a turbo.

300 flywheel ain't hard really. Decent turbo, most use the ats 093 with wastegate wired shut. Studded headse. Intercooler usually. And as much fuel as you can without blowing the pyro, properly timed with fresh fuel system and hopped up pump help. 300rwhp is a different story... Cam grind, etc

If you want to show off at school your money is better spent elsewise. why drop several grand on it when you coulda got an easier engine or used it for college

I love mine stock as a stove, If I want 300 hp I have a 72 Vette to drive around and look cool in, well as cool as a 60 year old guy in a vette can look

Ok so where do you plan to find 6.9 pistons with the larger wrist pin hole to work with the turbo rods increased pin size?

Hmmm well since you have a turbo already you could have a pretty powerful idi for $2500. Definitely gotta get a Moose Pump then for sure and an intercooler then pump up the boost as much as you can. Head studs are definitely in order also if you want to pump up the boost up to about 20 psi or to anything above 15 psi. Also like type4 said, a torque cam would be good for towing and its pretty cheap. I have DPS injectors and I don't mind them. They seem to make decent power but some seem to have had problems with them in the past. There are also Moose Misters which I hear are awesome or turbo injectors which will make decent power.

This is a good point. Gotta love Oilburners.

I guess the 7.3 would be a good choice for that reason.

The more I think about it, whether it's a 6.9 or a 7.3, I think the best thing is just to limit the boost to 20 or less but get it on early, with a turbo efficient at that level of boost, try to cool down the intake charge as much as possible, put the modified db2 on it and be happy with what you get. Of course, a little tinkering here and there may get it running even nicer.
