450cc dsm injectors, what is need to plug and play?
putting a set in my friend's 96 civic, do i need the clips or will they plug and play? also is that resistor box needed? thanks in advance i appreciate it.

Clips are also available at your local auto parts store, anywhere from $3-16.
just help our friendly honda tuner out....remember we're all imports here, majority, lets help out each other, so we can all eat domestics together
This is from sourced from another member:
You need b16 lower injector seals, as the 450cc injectors are a bit longer.
You can use the stock DSM upper injector seals. You'll find tha the DSM 450's are a sweet fit on the stock fuel rail.
For my jrsc, I had to make 10mm spacers to properly space the fuel rail, from the intake mani. For stock mani, I think you need either a 6mm or 8mm spacer (x 3 of course).
Now for the wiring.....
Because the DSM injectors are a saturated type injector, you'll need a resistor pack of some sort. I've seen people use either of the following methods to do this.
1 - Run a 10ohm/10watt resistor on the yellow/black wire on your oem injector plug. This is an effecient way to do it, but one I haven't tested yet (my resistors are on backorder).
2 - The tried and true method of wiring is as as follows. Buy an oem OBD1 type resistor pack out of an EF civic, or gen 1 integra. Run your 4 yellow/black wires from the oem clips to the red wire on the resistor box. Then run the black output wires on the resistor box to the new injectors, to replace the wires you ran into the box.
Voila! you have tons of fuel now.
FYI, run a search on hostboard, and clubsi. I know there is a great set of pics from svanhook around somewhere that really helped me to the swapover.
Good Luck.
thiis a ltttle more info for ya!

umm...do you even need the clips? I'm running dsm 290cc's right now and I just had to dremel out a bit of plastic on the injector's socket...
