In my experience with his injectors- yes, they are remans- the finish is not factory and, you can see where someone did a lousy job on the masking around the composite section as there's overspray seen there.

The OEM finish is applied PRIOR to assembly and, it's either powder coated and baked or, it's an two-part epoxy system. Both are EXTREMELY impervious to all chemicals including brake cleaner.

On FIVE-O injectors, this finish came off with gasoline that had an additive in it. This happened when I was designing my fuel rail system and, I had to take it off a few times to make the mounts thus spilling gas onto them.

So, I can say with absolute certainty that they are remans- not new. He even told me that they were new after I'd questioned the fit and finish and, at that point, he told me to return them to which I did.

I also had them fully tested for both flow rate, leak testing as well as full electrical testing prior to installing them due to suspecting remans vs. new. I've been there before and it was a bad experience in the past so, I tested them out first. I have a person that has the testers and cleaning machines. He even does complete tear down and rebuilds injectors of all kinds as well. Our tests proved the Five Os blue tops to work just fine.

However, the worst we've seen that were "new" were Accels / Lucas. Lucas makes some 4-hole jobbers that are very bad and, I tested those myself- bad bad bad. No good. Spray pattern was whacked, flow rates were all over the map, not rated properly, OHMs were all over the place- way too much variation and little to no quality control over the final product. Junk- period.

Here's another issue that I found with their injectors- the contacts are much thinner than OEMs. The blade thickness of their reman contacts were >10-15 mils delta. So, what is the problem? I'll tell you what it is: OEM Siemens run blade contacts thicker ok, and, the OEM harness has has a larger opening that mates with the injector blade contact. What you get is, sloppy fit thus under vibration, intermittent connection thus, tripping a code for misfire or, injector CKT Open or shorted OBD fault code.

This is a real pain in the **** because, many have no idea what the hell is going on and, it took me a while to trace it out. I had measured everything from the PDC all the way out and everything (including the PCM) checked out fine.

I removed the injector and peered in many times but, the last time I had a Five O injector in my hand and a Siemens, I noted something. I've got a keen sense of dimension by eye and, I noted the Siemens contact blade looked substantially thicker compared to the Hawaii Five O injector.

I grabbed my dial calipers and took measurements. Sure enough, it was way different. I think the average across the set was 15 mils. I then measured the contact blade gap at the harness and, it was already oversized / stretched open beyond even the Siemens thus making it even worse when running Hawaii Five O injectors.

Even after closing the gap up to mate better with the HFO injectors, the composite body retained it's memory thus springing back and opening up the gap again. After that, I knew those were going to have to be replaced.

Now, I bought his harness and, the plastic is very thin, it's not OEM rated and, it cracks so, just handle them with kid gloves. If I had known that, I would have either molded up my own or, sourced a more robust replacement.

Overall, I am not impressed with Hawaii Five O's stuff other than the low, low cost as normal cost on the blues is around 100.00 a pop. He's half the cost and, if you get a good set and have a way to test them PRIOR to running them, then you can ensure you've got a know, good set to run in your vehicle.

That explains why the stock connectors did not work very well. The blade thickness.

YOu can splice the connectors yourself. Not that big of a deal. I didn't solder them, because I didn't like the idea of a soldering iron in my hand while sitting over the engine compartment. Fire of 3rd degree burns. ANd I did not feel like tearing out the wiring harness.

 

So, how's it running?

 

Just got finished. Had a plug boot that the wire slipped out of and i had to buy some more tools.

Just started her up:
Some D'ohs:
Forgot to put the serp belt back on
Forgot to route the throttle cable under the pendulum, so the gas pedal didn't work---FIXED


So, I started her with everything finished, and she idles great. Have not driven her., Wanted to check the injectors for leaks and see some other things I forgot (Map sensor vac line).

I am so paranoid that I when I gave it some gas from inside the cabin, I was like "Damn I have a vac leak. I hear a sucking every time I press the gas." But i forgot that you tend to rteally hear the TB if the air cleaner is off.

I will get the air cleaner on, and take her for a spin. I need to get a 6 pack. I have been working since noon with no beer. I am not a guy who has a supply of cold ones handy. And I am married with 2 kids. So mabe I should.

I will be back in about 20-30 mins...hopefully there is no fire. Please cross your fingers and pray to whatever God you believe in.

hope she runs great. im looking forward to getting some 4 hole injectors. maybe it will help with mpgs and maybe just maybe a little bit more of pep

 

OUTCOME:

Well, the injectors, MSD and tuneup made it worth the time. I had the injectors and MSD on hand so it didn't cost me anything there.

The old cap and rotor were in pretty good condition, as were the plugs and wires. But, the new tuneup could not have hurt.

The truck has smoother acceleration. I was granny driving it, so i decided to floor it. Well, the truck likes AIR and lots of it. There was some power in the upper RPMs, but nothing like "WHOA" more like "Cool."

I tried to drive up a hill with OD on to see if the truck would not die. Well, there was nothing changed with her hill driving in OD, but she never went so slow that she needed to downshift.

I think this mod will may dividends once my SCT from hemifever comes in. ALl I did was just mod the deathflash.

MPG increase:
Yesterday morning I reset my MPG meter in the truck before I went to work. i drove to work, then from work to autozone, then home.
9.1 MPG
Today, I reset it before driving it. I drove to the liquor store and back. A little shorter, but 2 massive hills on the way there.
11.4 MPG

So, I think the injectors and MSD are a good choice for upping the MPG, but they will cost you about 340 for the injectors, 199 for the MSD, and 46 for the MSD coil. If you can get a MSD cheap off ebay, it might be worth your while. Or find someone with a 5.0 mustang who is parting out his car.

I remember the best it got highway was about 15.5 MPG. I will test that out tomorrow.

 

Yeah, that is what I would say. A LITTLE BIT. It is noticeable, but nothing you would tell the neighbors about. If you have a SCT, it would probably be really good.

My 1996 5.2 with these same injectors and MSD (and mopar 92 octane PCM) got 16 MPG (average). I also had the pro-flo air cleaner. Getting an open element would probably help for the MPGs.

Next week i should have the SCT, so i can let you all know how that works.

 

awesome, i will be getting the SCT soon if funds and wife will allow me

 

all you need is 275, and Hemifever will get you a performance tune and a SCT. He said that RRs, injectors and MSD will not warrant a custom tune (375). But if I put heads or a cam on, then I would benefit from a custom tune.

275 is not that bad, but it takes a bite, especially with summer coming. I can hide that much from my wife in about 2 months. I basically depleted my secret stash with this project (still have to do the plenum, 180*, SCT and 1.7s)

PM hemifever.

 

ive already pmed him. i got all the info, im going to go ahead and get the custom too since i will be upgrading to the 408 sometime in the near future. i know i can get a can tune and upgrade later but i would rather get it out of the way so i can nickel and dime on parts for the 408
