What is this Item?? Anyone

The item in question is that little box in the upper right hand corner... it has fins on it etc.

I am just curious, cant seem to find anything related in the helms manual.
I have a 1992 Civic Si

(B16a swap)

Resistor box, obviously the guy who did the turbo, used DSM or Prelude (or something else) injectors which require less current.

It's off an EF or Prelude, all it is is just a bunch of resistors in the box.

ShoGinn

weird.... this is what I hate about acquiring a modded car. Car has stock injectors right now... car runs fine.. interesting

ABK

how do you know that they are stock? I would change them out if they trully are stock. I don't know why that guy would go thru all that trouble of taking them out and resoldering the plugs (if DSM) just to sell them for $30?

EK22snatch

yeap, i got that lil resistor box chillin in my ek-H22 hatch. its m4d jdm

ShoGinn

lol, anyways here are some better pics. I dont think those are DSM injectors. If they were the car should run like crap.. it has no fuel control except FMU and VAFC which is 0'd out

could be stock prelude....ludes and accords also used peak and hold injectors long after civics gave them up...(like like 97 or soemthing) oh and stock lude are like 345cc's

ebp 99 si

310cc

accord387

could even be dsm injectors (i dont know the visual differences)

ShoGinn

ya this is confusing me... wonder why it has it?

So is the resister box not normal even for a B16 swap??

no it's not unless you run different injectors (I fogot what those injectors are called). The reason why they use the resistor box, because civic injectors operate on higher amprege then DSM injectors or Prelude or EF. So they take a resistor box from EF or prelude and use it to lower the amprege.
So yeah to me it looks like those are stock injectors, and resistor box is not even plugged in (plug with all the yellow wires is unhooked and capped off with a bypass). Can someone else get into this about this, who actually done this before?


Yep I double checked it is unplugged, and it looks like you are running stock injectors. I would change that out ASAP because you might lean out your motor. Do you still have a contact with the guy that you bought the car from?

Yep you should defetly get some DSM injectors and hook them up. You are going to bore out the O rings to make them fit, if it's not done already. You also have to wire up the DSM injector plugs instead of civic ones and just hook up the resistor box. Then get your car tunned. I wouldn't even drive it around like that because you might blow that motor.

ShoGinn

Hmm, Im pretty sure its connected to something

As for the car running lean, according to a/f ratio its running fine (from ghetto low-band)

My guess is instead of installing stock saturated injectors he installed peak and hold ones back into it in preperation to do DSM injectors... But I cannot confirm that as of yet.

Any way to identify injectors?

Thanks for all the help thus far

accord387

that resistor box is wired in. If you search im sure you can find ways to identify the injectors. Since ur boosted im going to assume you have dsms. Just try a search and its most likly going to be in archives. I'd do it but i dont have time right now.

ABK.... ur reasoning behind the resistor box i believe is completely wrong.

ABK

ok newbiees first of all take a close look, the plug from the resistor box is unplugged it's right to the left of the resistor box (infact it's touching it). And the injector plug is unplugged and capped off with a jumper (it's the one with all these yellow wires, some blue and I believe red).

As far as for injectors just let me get some pictures of a 1st and 2nd gen DSM injectors.

These are 1st gen DSM (notice totaly different plugs and injector tops are blue):


2nd gen I believe got a green top and same plug.

the ones that you got on your car look like and I'm almost 100% sure are civic 240cc injectors.

ShoGinn

Here are some more pics



As you can see its plugged into the car, and one wire is tapped off into that other blocked off harness....

is there another thing that is supposed to connect those wires together? or how does that work without the box?? im confused.

ABK

ok now it looks like it's plugged in really hard to tell. Then my guess is that you are running Prelude injectors (wild guess). You just find the guy that you bought the car from and find out WTF he put in this car.

gots_a_sol

in this picture, it looks as if they are blue tops

also, when i put in my dsm injectors, i used the stock injector clips on them

ShoGinn

the tops are black... thats for sure...

car would also run like *** with AFC 0'd out

im baffled lol

I wish the last 2 pages in my 92-95 helms manual was actually readable so i could figure out what all those plugs exactly are

ABK

the plug that connects to resistor box is an injector plug. it's capped off with a jumper so that the injectors get the current. If you take off that cap your car won't run (injectors won't work). So you take off the cap and hook it up to the resitor box which just lowers the current flow.

ShoGinn

ya I just noticed that... so it looks like they removed 4 of the wires and put them into the resistor box plug so that it routes the power from the main relay through the resistors and outputs it through that one wire to all the other injectors...

It all makes sense

*sees the light at the end of the tunnel*

Ok now that we have determined wtf is goin on now i gotta find out which injectors they are so I can decide my next course of action.

Thanks for the help btw all... now if i could only get this search to function right so i can get some injector specs.
