Good source for rebuilt or new injectors?

[Eddo Rogue]

I got some replacements from rock auto coupla years ago, and they seem to work fine....They were the Bosch, like $60 bucks for the set. They had the motorcrafts for $60 each.

I want to say @ecgreen bought Accel injectors. Had no issues with fuel delivery and ran well.

I looked at them once awhile back and they were spendy. Probably in the ballpark of Motorcraft.

I picked up a used factory set for my 2.9L on here. I was going to send them to @Shran guy.

I need to get that process going...

I'll probably keep the stock size.... never intend on going over 3.5 psi, but I'm cheap, and may try to retune for 89 or 87, so moar fuel or moar injector may be needed. Not certain.



Now I'm nervous... when you say broke.... what did it do?

Not completely sure yet. It was shifting to third at 5500 and went thunk and died. I think it either broke something in the passenger side valve train or the timing slipped. There was no metal in the oil. I'll tear into it one of these days.

Looks like they don't carry the ones for the 4.0.

Bummer.

Finally found the old post I was looking for.

@ceeshad mentioned https://www.cspinjectors.com/ as a source.

Anyone else ever use them?

So, CS Performance got back to me today on a set of reman-s.

How uh... how precise does the flow matching need to be?

 

[Uncle Gump]

Yes...

Apples to bananas but my cobbled together supercharger on my 4.0 ohv just barely has enough injector to handle 5 psi at high load. Afr is 13.2-13.4 at WOT. I run 91 as a measure of safety, only issue I have had is timing seems a touch too spicy sometimes, I'll tune it eventually.

Actually, this is helpful.

I dont plan on going much above the 3-3.5psi baseline. But only options I'm seeing are the stock 20lb or the Ford performance 47lb. So, it looks like I'm "stuck" with the stockers.

I'd go higher, but I don't want longevity to become too much of an issue.

Have the tuner for it in the center console. Probably will get the tune adjusted after a while. Haven't run the tuner in a while tho - 5 star tunes suck, stock one was better.

For posterity: @bobbywalter says 1%

I found a chart somewhere that breaks down injector part numbers and flow rates, the set I've got sitting on a shelf are out of a duratec taurus and are 24#. The tune would be custom done I've got a tweecer rt ready to go should the need arise. I'm anticipating needing more injector once I get the clapped out m62 redone because the math says I should be around 6.5 ish psi and I'm at 5. The general concensus is the rotating assembly turns to mashed potatoes above 7 psi so I'm on the edge, haha.

I have a m62 on the shelf... cute little thing lol

They're not large but it was what I could get that I didn't need to extensively modify to fit. Gm 3.8s are what are plentiful here, the gm m90 is too long, it would have needed to be shortened by quite a bit to fit. There are zero supercoupes in junkyards local to me, they would have been ideal. I get full boost at 1400 rpm and can hold it all the way to redline with a 2.2 inch pulley which spins the charger at 14,000 supercharger rpm at redline. I have a build thread in the forced induction section if you're interested.

What about the SC14? rare as hell, but probably one of the coolest stock blowers out there. I have one of them on the shelf as well.

Mercedes did a m62 with an electric clutch as well, they're not common either
