935Motorsports supplied Injector ID

[theKnifeArtist]

so i just bought a set of used Denso 550cc Injectors from 935 Motorsports on eBay.

http://cgi.ebay.com/ebaymotors/ws/e...7053&viewitem=&sspagename=STRK%3AMEWNX:IT

It says they are high impedence injectors, ok.
They came in.
So today i'm looking for clips for it online and i get some more info about denzo injectors.

I came across this:
ND made some low impedance 550s which are direct fit for the MKIII's fuel rail. Their part number is: 195500-1370. BE CAREFUL! for some reason ND used this same part number for their high impedance 450cc injector too. How do you distingush between the two? Look at the notch on the top of the injector connector-if it is in the center its low impedance, if its offset to the side, its high impedance. -grimreaper

So i check out mine

was gonna get them cleaned and rebuilt.

Perhaps a mistake was made and i recieved smaller 450cc injectors? .

I would contact him. I have never had problems with him, and he may have not known.
Why start a thread saying that he cheated you when you haven't contacted him?

true..

 

[theKnifeArtist]

i wanna make sure my story is straight. and some kind of better reference if so.

 

[lewis15498]

Yeah, im pretty sure if you let him know he would apologize and make it right asap.

 

[theKnifeArtist]

somehow i dont think it was a mistake.
i dunno, i'm just a little angry about this.
but you're right. i'm gonna email him right now.


Can anyone confirm this? Or how a better source of info?

 

[Jeff Lange]

Measure the impedance of the injectors and have them flow tested. This is the best way of knowing what you have.

Also, contact him, and see if he had them flow tested or what his source is for knowing these are 550cc injectors.

For all you know, someone pulled a fast one on HIM.

935 is slow and has terrible communication and customer service, but i dont think they would intentionally rip you off, i would look into it more before getting too angry

The info is legitimate, originally written by drjonez:

Yeah, christ - contact Rob first and give him the chance to make things right before going off the deep end.

This x1000

right now you are guessing they are not right. You need to verify that they are or not.

 

[theKnifeArtist]

Measured the resistances and confirmed high impedence injectors.
Reading is 13-14 ohms on the injectors.
He did say they were high impedence, and also gave the resistor pack plug as you can see in the picture.
Get them flow tested to determine flow rate? No thanks, I'm not paying that much money to determine i got a wrong part.
I'm waiting on an email reply.

my bad

 

[figgie]

ok folks. ONLY warning. This is theKnifeArtist thread. No need to insult, lambast on his experience, after all it is his experience (mastergrader, looking at you specifically).

Yeah I definitely agree with this post. If you don't call them it is likely they will not respond, I have tons of emails to him regarding my brake order (rotors/lines/pads) without a single response (ordered in June, finally have the rotors, lines and rear pads-about a week ago) but somehow the front porterfields didn't come, hopefully I get them by this Friday when I move out of my college house). If i didn't call I didn't get an answer. Rob seems like a nice guy but customer service is not 935's forte.

 

[rodel]

Those look like 1988 RX-7 Turbo II, 195500-1370, 550 high impedance injectors

 

[wardog]

Yeah they are the Red High Imp 550s cause i have the Tan Low Imp 550 Injectors form the 87-88 Turbo II rx7....:icon_bigg

 

[monypit]

where is agood place to have injectors flow benched now a days?

 

[suprra_girl]

Yup 550 high impedance. I have them in my car
Don't stress... get em cleaned, bypass resister pack and go

 

[theKnifeArtist]

Woa woa.
Based on all the discussion on this thread, the high impedence 195500-1370 denso's are 450cc
