I am in the middle of the s4 to s5 intake manifold swap.
Today I took my injectors to work to get them cleaned and found out that one of them would not pass the leakdown test. (leaked after voltage was removed). I have an '87 gxl and am wondering if I can use the 560 injectors from a turbo for my secondary injectors? No major mods. Just intake, rb header and no cats. Does anyone know the flow rate in ml of both the primary and secondary injectors for the 87 n/a? (p/n 195500-1350) Do they flow the same? Mine came out at 120ml on the primaries and 114ml on the one good secondary. I would think that since all 4 injectors are the same part number, they should flow the same when put under the same conditions. Does the computer regulate the flow rate of the primary versus the secondary? Or do I have a problem? Last thing (sorry so long, I normally don't post because I DO know how to search) Does anyone have a 2ndary injector to sell or trade I have 3 just cleaned p/n 195500-2010 89 n/a. OR if I can use the 560 injectors I would be looking for 2. Please help. Wifes car. I was gonna do mine first but her PD was leaking and now an injector that leaks when shut off.
thanx.

The N/A injectors are 460cc and the turbo ones are 55cc. You do the math to convert to ml. You need to check the year of car you have because some cars used low impedence injectors and some use high impedence injectors. They made a switch in the middle of '87. I'll look around and see if I can find the exact VIN number for the car that started the high impedence models.

 

info- 1cc=1ml (metric system is cool that way)...just take the injector and ohm it out- if it's about 11 ohms, you have the high impedance (later) ones...Jun '87 was the transition point for the injectors (I forget the exact VIN also)

 

In June of '87 VIN # (last 4) 7601 and higher are high impedence injectors. The cars with low impedence injectors has a resistor back between the ECU and injectors to up the resistance from 2-3ohms to 12-13ohms.

 

They are 2.5ohms. I really appreciate the quick response, I am wondering if 560's are too much fuel to use as primary or secondary injectors. I am looking for some options here. (go fast)
thanx
I have a list of part numbers and impedence etc...so it is easy to tell which is which (high vs low)
the 3 that I have for sell or trade are 14.1

 

The 550 TII injectors are WAY to big for N/A secondaries.

 

They are 2.5ohms. I am trying to find out if the 550 injectors are too big (too much fuel) to use as either primary or seconday injectors. I know which ones to use if they can be used with my limited mods. Thanx for the quick response though. The 3 that I have for sale or trade are about 14 ohms. We knew this from part numbers.
thanx

 

sorry, rookie poster

 

They are too big. I have some 460s I can trade you..

 

thanx J-rat.
I will shut up now before this lag makes me look as dumb as I am.

 

sorry guys, I figured out where you were going. I am not trying to use the s5 injectors. J-Rat, s4 460's? How soon can they be in the mail. I can mail A.M. Thanx!!!

 

I am sure I have like 3 460s layin around. I cant comment on the condition, but they came out of a perfectly running car.

 

sounds good to me, the 3 I have were just cleaned and work great.
missing seals/o-rings though
lets set this up.

 

PM me your info.
