IDENTIFY THESE INJECTORS AND WiN...
 

A BRAND NeW...











Well, I dont have anything to give away, but you will have my eternal gratitude.

The injectors on top are stock bank 2

The injectors on the bottom are my new bank 2. The fat ones are Rochester 780cc/min 17113742. I need to know the skinny black ones to find their latencies. They had hand written scribble on them, but I did not record it. No other identifying casting marks. These were purchased from Mazsport early '08.

I should have used a camera with my macro lens, but it is too late now.

Thanks!

Siemens I think.... 60#/hr long Machined to fit :)

Crap. I just realized I have a major problem with the injectors I have. The big fat injectors are low impedance. The stocks are high as well as the Siemans injectors.

Thanks for the info dan.

This might have been fine on the Int-x (might have a resistor or some good heat sink) and is likely a very good idea for response, but I dont know if the stock pcm (with an accessport) can stand to have a secondary running low resistance.

Any opinion on this would be grand.

{off to do some searching}

They could easily be high impedance RC has a 785cc HI set that look identical as well....I have a set siting on my workbench..I can check them for you on Monday when I get back from LA. AFAIK they are all high impedance

Are you talking about the thicker set in the pix? Those unfortunately are almost certainly low impedance. They have a number cast on them that IDs them as rochester low impedance injectors. Looks like I need to get another set of injectors.

I am thinking a matched set of four 650cc HIs from RC, but I am looking around. If you know of a good source for injectors and grommets, let me know.

Not looking forward to ripping off the UIM again.

I have a set of 4 550 Denso's in mine right now......and the Seimens 650's

Are the seimens in or out of your car? They for sale?

Why not just run 1 set of yellows for the primaries (380), run 1 set of yellows for the secondaries (380), then the skinny black (seimens 650's) for the primary 2s? This would be enough fuel 400 crank hp.

get an ohmmeter across the terminals. 2-3 ohms is low impedence, over 10 ohms is high impedence

IN.....Sorry :( Running them as Primaries :)

This is a good idea. This is why I come to this crazy forum.

I was keeping the reds in primary for idle and cruise. But 290 to 380 should not be that big of a decrease in granularity. Might try this out.

When you say "machined to fit" you mean they were modified? If I get another two from somewhere else, are they not going to fit?
