OK, before i get flamed for this, let me get it out of the way. I searched, found nothing.

Does anyone have a write-up on using the 450cc injectors in a B18b1? I know i need resistors, but honestly i can't remember whether we need to convert TO peak and hold or FROM peak and hold (to saturate). Maybe i'm just stupid.

So does anyone have any detailed instructions on this set up? i.e. with pictures?

you need to convert from saturated to peak and hold. you can obtain a resistor box out of a 88-91 crx or something like that I beleive. check ebay, they have some there. the injectors should just pop right in, mine did, but I have heard some people had to bore it out a little to fit it.

awesome, thanks.

So does anyone have any pictures or can anyone tell me how to wire up the injectors throught the resistor box?

little ghetto picture....

using the resistor box is A LOT cleaner. look at my pic and notice the Honda plug that i used coming off the resistor box. it's the plug leaning on the Clutch fluid reservoir.

Not that it realy matters, because liam821's write up will work, But...

The yellow and black wires are positive power, not grounds. The other colored wires from your injectors that lead down to the ECU are the grounds. In the electrical world... it's easyer to control a ground switch rather than the positive power switch. (it has somthing to do with a back EMF in a semi-conductor)

Just an FYI

I also recomend using a resistor box. They are cheap, and look like they were ment to be under the hood. I got mine from a prelude at the local junkyard for $3. If you go the junkyard route... take a multy meter with you so you can check to see if all 4 resistors are good. (one lead to the red or black wire, then check the other 4 yellow/black wires with the other. you shlould read 6 to 8 ohms.)

Good luck

yea you are correct. that drawing is just old.

It doesnt matter if its on the ground or the positive. both will work.

im also using the DSM 450's but i have one yellow/black wire and 4 red/black wires.. how do i hook this up?

booscivic · 11-29-2003, 02:22 PM

check under ladysman he did a really good write up on that!!!

You can also steal the resitor boxs out of Accords and Preludes, 5th gen accords have one i know of as well as 4th gen ludes.
