LS1 coils onto sr20

[AsleepAltima]

this was too easy. i almost gave up on it because i couldnt find the right wiring diagrams for it. i found what i needed after 2 days of web searching just about every google link i could with the words, "ls1" "coilpacks" and "sr20det" in it. lol.

if anyone wants to do this conversion, its stupid easy.
get a 2nd big gray plug (the sr coil pack harness plug) and using this diagram

wire the wires to the gm coils using this color code/wiring code for the ls1 coils

A, Black, Ground
B, Brown, Reference Low
C, Ignition Control, 1/Ppl 3/LtBlu 5/DkGrn 7/Red 2/RedWht 4/DkGrnWht 6/LtBluWht 8/PpplWht
D, Pink, Hot in run and start, Inj 2 15 amp

the wire colors in bold are the negative triggers you need for the big gray plug wires to go to.

once you have that done, go to your ignitor, and using the corresponding "e" and "i" pins - just wire the wires across the ignitor and delete the ignitor altogether.

i soldered and heat shrunk all wires, installed the coils (loosely for now, making the brackets for each individual coil tomorrow) and it fired right up. it idles silky smooth and throttle response is crisp and rolling into boost is just as smooth. cant wait to see how well they work on a hard pull.

if i missed anything, just ask and ill answer. its super easy to do and as far as i know, this is about as complete a thread youll need to get it done. without pics but oh well, its still easy to explain.

youre welcome! :)

ill try and get some pics up after i figure out how to make a good bracket for them that isnt too retarded. i found some perfect metal bracket stock at homo depot that looks like it will do what i need it to do. i might just go ahead and lengthen the spark plug wires too.
