Anyone know anything about Siemens injectors? February 27, 2008, 03:11:53 PM I found some Red top Injectors at the junkyard. They are identical to Bosch units but the manufacture is Siemens. There is only one number and that is 4663376. Quote Selected
Anyone know anything about Siemens injectors? Reply #1 – February 27, 2008, 04:07:08 PM what were they in???Red tops were used in the '89-'94 super Coupes... Those are high impedance 30lb units... The '95-'96 got the dark blue 36lb units...Think I'm correct on the years... Different OEM applications are various colors... Had some purple Chrysler ones at one time.. Quote Selected
Anyone know anything about Siemens injectors? Reply #2 – February 27, 2008, 04:11:14 PM 3.3l Dodge intrepid. I've been searching the net for an hour now to no avail.89-93 got the 30lb and 94-95 got the 36lb. No 96 SC Quote Selected
Anyone know anything about Siemens injectors? Reply #3 – February 27, 2008, 04:14:15 PM Here they are. Got the 19lb units today and the others today too. Quote Selected
Anyone know anything about Siemens injectors? Reply #4 – February 27, 2008, 07:34:01 PM are you building a v-12 with an extra bank of injectors? Quote Selected

Unless they're from a high output engine I doubt they are more than 15/16lb inj... Also mfgrs used different fuel pressures, so can be difficult to compare... Quote Selected
Anyone know anything about Siemens injectors? Reply #6 – February 27, 2008, 10:28:57 PM Most Mopar applications use 43 PSI. Some use 55 PSI. Quote Selected

Anyone know anything about Siemens injectors? Reply #8 – February 28, 2008, 12:23:12 AM I can't find any info on them yet.....Not even the great Stan Weiss has info. Only that they also came in the 2.0 liter 4 cyl. motor in the Eagle Talon.http://users.erols.com/srweiss/tableifc.htm**EDIT** Found some cross reference #'s here: http://www.fuelinjectorwhse.com/injectors.php?id=MP1002I'll keep diggin' Quote Selected

Anyone know anything about Siemens injectors? Reply #10 – February 28, 2008, 09:09:38 AM Rig up a injector stand, test the flow...Take a old fuel rail with pressure regulator, and cut off all but one opening... Then plug the open tubing, connect it to a fuel pump and start sprayin'... AHHH if it were only that easy... BUT if you use approx 8v on the injector, it will fire and not over heat the coil(assuming it's a 14 ohm coil)... You're gonna have to figure out how to hold the injector in the fuel rail...Spray some kerosene(don't use gas) in a measuring container, after 10 min check the contents... Be a good idea to verify you setup with a known injector first... I'd do this away from any buildings you'd like to keep...For injectors you don't really care about the test could be done with water pressure(most areas have 30-40 psi)... I washed out a set with water that were clogged with orange soda(I did hit them with WD40 after the water)... Worked fine when reinstalled... Quote Selected
Anyone know anything about Siemens injectors? Reply #11 – February 28, 2008, 09:25:34 AM I could do that. I think i have a 2.3 fuel rail that I could butcher down at the farm even. I could compare it too 14lb, 19lb and 24lb units. I already measured them and they are high impedance units. Quote Selected
Anyone know anything about Siemens injectors? Reply #12 – March 01, 2008, 11:56:58 AM Quote from: CougarSE;206722Yeah I found that site earlier. I'm at a loss here.without even looking, i can assure you that my past experience working with this company and thier products will tell you these injectors are of an emissions improvement capacity. This all could be solved by just calling Siemens. Your just going to have to speak to an applications engineer or a sales engineer. Thats where i would start for a spec sheet. Im just guessing but there probably isnt much specail about them other than atomization characteristics for fuel reduction. While your at it, since it does have thier name on it, search the PTO for any new patents. Quote Selected
Anyone know anything about Siemens injectors? Reply #13 – March 01, 2008, 12:03:45 PM your not going to burn up the internal coil keeping power on the injector. I have energized injectors to clean them to and they really dont get too warm at all. While in use, the injectors are constantly energized / de-energized with an average of being continuously on doing the math.the fluid you push through keeps the coil cool so you should be fine.I did the same with a stock fuel pump vs a SC fuel pump to compare flow rates over identical time frames.

Anyone know anything about Siemens injectors? Reply #14 – March 01, 2008, 05:17:42 PM I'm wondering if these are off of a Flex Fuel vehicle. I didn't take the time to look at the junkyard but I know Chrysler had some early FF vehicles. I've read some other junkyard scrounging threads on other forums and they all point fingers at FFV's to find higher flow injectors. Quote Selected
