Injector install?

[Swayse]

How hard or easy are the injectors to install? I've done about 10 or 11 ISB injector installs without a problem, but these expensive injectors have me a bit worried. Any special tools needed?



I'm thinking of doing injectors, stage II or III. Do I really need a boost fooler if I do injectors since mine is a SO? Would EGT be a problem with the stock boost elbow with stage II injectors? I'm waiting on TST and EDGE for the big boxes, but I'm getting a bit tired of waiting. I really don't want to get a pressure box that will be a throw away once the big bad boxes come out. I wanna do injectors anyway but didn't plan on doing them until next year. All I know is that 18. 04 at 74. 5 mph feels a bit slow and this has to change soon.

It sounds like TST is going to be out at the end of the month. They were set back a little cause the timing didnt work right after the units were assembled. They said nothing would happen till Mark gets back from May Madness to give the approval on whatever their fix is. I got a rail box somewhere on a mail truck and I figure when the timing boxs come out Im going to stack em.

Injector swaps are pretty easy in 03's.



Here are some directions:



You may need to remove rear engine lifting bracket (15mm bolts)



1. Remove plastic vanity cover

2. Remove hoses from breather bottle on top of valve cover.

3. Remove Valve Cover, Remove intake arm and grid heater.

4. Remove wire harness connections from rail and combo (map/iat)sensors, also remove injector harness connections (3 on the side of rocker box)

5. Loosen and remove all injector wires from each injector.

6. Remove rocker box (mid piece between valve cover and head).

7. Completely loosen all injector lines at the head, next remove bleed off banjo from top of rail

8. Remove rail feed line from CP3 fuel pump.

9. Next remove securing bolts for common rail and securing bolts for fuel lines, this will allow you to remove the common rail with all fuel lines attached.

10. Remove all male connector securing nuts and pull male connectors out enough to allow injector removal.

11. Number each Exhaust rocker, remove each exhaust rocker (sometimes it maybe necessary to bar over or remove intake rocker to swap an injector), do not loosen adjustment nut.

12. Remove all injector securing bolts.

13. Next pull out injectors.



Torque specs:

Injector securing bolts: 8mm 10nm

Injector wire nuts: 8mm 1. 25nm (thats extremely light) Be very careful here, if you break off the copper stud on the injector, you'll be having a very bad day!)

Rocker: 10mm 36nm

Male connector nut 24mm 50nm

Fuel lines: 19mm 31nm

Intake air arm 10mm 24nm

Rocker box bolts 10mm 24nm

Valve cover and vanity cover bolts 10mm 24nm

Fuel line and rail securing bolts 10mm 24nm

Remember the Yellow and Brown wire nuts always will be closest to the intake side or rocker.



Be careful to isolate fuel system components to keep debris out of system.

I bought the injector tube puller as well as the injector puller from Miller SPX tools in anticipation of installing some stage IIs in mine. The injector puller looks interesting although there's probably another way of doing it. It looks like it grabs the injector down on it's side then you lever it up and out.

Why wait? Just like the EZ + Power Edge = Comp, so will there be a timing/pulse box to stack with the EZ type. Just do it.



Oh, you will need the boost module feature on any trucks with 2's or 3's.

Hmm

My head is spinning now, don't know which way to go. A pressure box would always be good to keep around after getting a big box, for trips to the strip. Injectors seem easy, a few more steps than the ISB, but I think I'd feel better letting Diesel Dynamics do them for me. I'll think on it a few more days.



Thanks guys.

You can do the injectors yourself. just take your time. The 3's are fun, too. C'mon turbo, hurry up UPS.

 

[Swayse]

Yep

I broke down and ordered a pressure box. I'm gonna do injectors, but now I can put it off awhile. I can't wait to try it out, I should get it Friday, go racing Saturday. Hopefully I'll be able to keep up with my nephew's HO Auto now, he runs a 16. 3. Then I'll let him try the EZ.
