Unless you have the pigtail adapters you have to use the coils specific to the year; the connectors in the harness aren't the same.

 

Also note, the Megacab did not come with MDS, even though it is tagged as a 1500, it shares parts with a 2500. Sounds like it possibly ate a roller on a lifter. Can't say for sure without opening it up though.

 

Yea this is my second megacab 1500. I always treated my old one like a 2500 and never had issues getting the right parts. I learned my lesson fast on that buying a used ranchhand for a 1500 and find the bumper mounts were 3/4 style. It was recently suggested to me that the 1500 mega axle tubes are not as thick as a 3/4. This is something i want to research yet. I never had any hub work or anything on my last 1500 mega

That what ive notices. Appears the 04 style is actually firing a different cylinder then the cylinder with the coil on the second wire.

 

Wasted spark ignition; when that cylinder fires it also fires an opposing cylinder on it's partial exhaust stroke. Supposedly for emissions. Worked so well that the 6.1 hemi never had it and it was gone for the 5.7 by 2006.

 

Well first battle is getting the 04 in driving condition so i can make sure the engine is solid before going to all the work. Found the fuel rail nut clips stripped out so that first battle as to why the injector is leaking then conitune on the diagnosis. Or maybe just swap the 06 intake over and see what happens lol

 

Simple fix on the injector, or could have been, the injector to rail oring had a big chunk missing, not as serious as a bent rail, but just as much work being he stripped out the rail bolts so i had to remove the intake to cut the bolts off and remove the rail.

Not sure if injector color means anything. looks like he only replaced 6 injectors, 3 on each side, not sure why this is. One of the non new injectors is more of a purple color vs the other 7 are red, not sure if it matters. All I'm using to determine "newness" is the nozzle area looks clean and shiny on 6 of them, other 3 are a discolored grey brown color.

I'm caught in the rabbit hole of of while its out I should.... my rock auto cart is still almost 1000 bucks for the swap.
Parts list includes plugs, coils, water pump, clutch, belt, necessary gaskets for parts being swapped, new timing set/high vol oil pump (200k engine I mean). Additional items include injectors, however this 04 having 6 new ones already its questionable thing, based on his assembly attempt, even they make me nervous.

One thing I want to address most certainly is the manifolds, almost everything else I listed could be addressed later in chassis with minimal headaches. The little bit it ran I didn't hear any leaks or ticks, but it definitely didn't get warm. I will reassemble and drive it some with any luck.

My main question I've been trying to get to is what's different from the 09+ (eagle?) heads to these old hemis. I would love to try the BD manifolds but they're only showing back to 09MY

What is a good aftermarket manifold that does fit, shorty headers would be ok also. I'd love long tubes but from what i remember when i had my last 1500 mega is there's not much for truck hemi motors, much less the 3/4 chassis.

 

Different color injectors are likely different flow rates. Not a good scene in a sequential fuel injected engine.....

 

This was a concern. due to the receiving truck being non EGR I figured to just use the intake plenum from the 06 including the injectors/rail.

 

So I had hoped to get the 5.7 running in the donor truck. I'm caught on fuel injectors. I replaced the oring on the injector and reinstalled, only to find the base of the injector leaking when pressurized, assuming it was twisted cracked when the other damage happened.

I can't make any of the other injectors leak at this point of course the leaking injector limits max pressure, I think its suitable enough test. I had decided to just replace all 8 injectors so there was minimal questions and if any issues arose it should be warranty on the remans. versus make one trip to town, just to then find another leaking injector.

My issue now is the 2006 5.7 mega/2500 motor uses a different part number injector then the 04 ram 1500.

The 5.7 in all applications for 2004 use the same part number, so it appears not to be an issue of EGR or not ect.
The 5.7 in 2006 uses the same injector part number for the durango and pickup applications, the charger/magnum/300 application has a different matching part#. Appears to not be a variation of EGR/MDS either.

I know gasoline injectors are not subjected to piston design like a direct injected diesel, however I'm curious if there is a possible issue here and which injectors should I get. I would guess its an emissions related change in pressure/volume and/or hole count? There seems to be no change in connector design. Is there a better performance injector I should opt for instead of either of these, maybe the Charger injector, or a different application?

 

Well I decided against getting the 04 running in the 04 chassis. It sounded good the little i ran it prior so I'm going to gamble.

The engine is pretty much ready to pull, just need to decide how i want to do the trans. There's seems to be no way of the engine coming forward before going up. The trans/tcase being wrapped in torsion bar/cross members doesn't look easy to pull either. My current plan is to slide the trans back the 2 inches i might have between the tcase drop and torsion bar cross member and home that's enough.

I'm glad i started on the 1500 because I think there will be way less head aches in a solid front axle chassis.

Was pleased to find a newer gates water pump installed, but hopefully that doesn't mean it got over heated. Must have been a really late model 04, looks like it already has the ports for MDS. I though 05MY was the first year for it to be installed on a Hemi



Also so far found at least 4 broken manifold bolts so my money wasn't wasted buying those parts. BBK shorties showed up, along with the dual exhaust pipes, just waiting on the stage 8 locking fasteners and remflex gaskets. but we got time, were not ready yet anyway.
