hey guys looking for some advice on the best way to go about cleaning everything up and fixing everything. this is my plan clean up as much sludge in the degas and drain the radiator and block completely then tear it down and throw a new oil cooler(probably the cheapest dorman i can find) in it and go through the simple green, restore, restore + flush and then run it for awhile( couple thousand at least), with a coolant filter. then do another full simple green restore, restore + flush. Tear it down and put a new Ford oil cooler EGR delete, studs, gaskets, renegade 175cc sticks with stock nossels, new water pump, new radiator hoses, new degas, and have the old radiator flushed and roded and new seals, ELC coolant and a good custom tune.... any suggestions?

 

That sounds like a really good plan. Very thorough. I was nervous at first when I read cheapest oil cooler (probably Dorman) . I see why now though. Good call on replacing radiator hoses as well.

Never heard of renegade injectors... I would stick with a well known builder. What's your power goals? Do you think you even need the bigger sticks? Are you going to upgrade the air side? (turbo).

What year is the truck? I see 03 EX, is this an excursion?

 

I figured i would spend the least amount of money on a cooler since i have to throw it away anyway, dont see how i can get the system clean without putting a new cooler in it. Renegade has been getting some good reviews on the other stroke sites....its either him or Warren. I have some stictation so i figured i would get them rebuilt while i had everything pulled out. Power goal is the normal of what everyone is getting out of a good race tune, nothing crazy. I am looking at upgrading to a mad turbo werks hybrid or a p max with a batmowheel but thats going to be when i get some more cash saved after all this. I was also looking at php gryphon so i can tune the ficm and use the downloader as a gauge (looks like its just an edge evo)

Yeah its 03 excursion cant figure out how to fill out the bottom sig and thats all i could fit in with my 97 cummins....

 

What site is the renegade stuff popular on. I basically hang out here and PSA now. Warren seems hit and miss, but he's got a good reputation and he's also standing behind his work. You take a risk using any rebuilt injectors IMO, to do it right they should be built from new Ford remans. If the only power you ever want is what a race tune puts out, why not just stick with the stock sticks?

 

I will double check where I saw renegade getting good reviews.....it was off a google search. So what is the difference between a ford reman and having renegade or warren rebuild them and machine out the body so it will hold 175cc? Not being a smarta$$ I know nothing about these injectors....I always see the.cc size and 50,75,100 over or stock nozzles. I am used to how the Cummins injectors are sized...5x.14 or what not. How much hp can you get out of stock injectors? I was thinking since I am going to have them rebuilt why not for the small pricw diff have the bodies mqchined out to 175cc in case i get hit with the bug and put bigger nozzles on at a later time ....

 

Stock injectors historically have only been good to around 430rwhp, but some guys seem to be pushing that envelope with different turbos, and FICM tuning, which has only gotten popular in the last year or so. high 400's have been done, I believe, but it takes a special combination of parts. I know the guys at MTW (mad turbo werks) were aiming to break 500 on stock sticks.

The cummins stuff is based off injector nozzle sizes if I understand right, just points out how many holes and what size diameter they are. We go with injector body volume (stock is 135cc or so), and injector nozzle size over stock. So a 175/50 is a 175cc injector with a nozzle 50% larger than stock.

If it's cheap enough go for it I suppose. I'm not sure that Warren or Renegade actually fixes the spool valve issues. My buddy was under his valve covers probably 4 or 5 times swapping injectors with Warren because of this. If you look at like RCD, you'll see they offer injectors built from new Ford, or from cores... your call. Warranty will be longer on new Ford units (all units are remans at this point, no such thing as a new 6.0 injector) The difference is some companies call them "remans" and all they did was swap on new external o-rings. Others dig in and fix the real problems.

 

i emailed the guy from mtw and thats one of the reasons i was looking at renegade because he is now selling them, i thought the spool valves and everything would be taken care of when you sent your sticks in to get fixed...i guess i need to get some more info about these injectors and what all is done. how many holes do these injectors have, havent been able to get that info yet. thanks for the help and info

 

I believe they're 6 hole standard, I know at one time 8 hole nozzles were available too, which help tremendously with atomization.

They might do the spool valves, but some places don't, ask that before you spend the money for sure.

MTW are good people, so if they're backing renegade they're probably ok, I just had not heard of them.

 

thanks for the nozzle info, 8 holes are great for the atomization. i signed up at psa also looks like a pretty good site, sucks being a private again got out of the Marines as a Staff Sgt again thanks for the info.

 

PSA is the best powerstroke only site out there IMO.

Seems the 8 hole nozzles were short lived, not sure who still offers them but I don't' see a lot of them around anymore. I can remember reading reports of guys having standard 190cc injectors with the 6 holes and doing nothing different other than switching to 8 holes and having smoke clear right up on them, and mileage going up.
