This will NOT work.rudedrift wrote:i have a valid question here.i have series II rb25. no igniter.since there is no igniter and the coils amplify thier own spark. meaning the ecu sends the trigger, off six seperate wires. to each coil.couldnt wire up the coil power same as you guys, ,run the factory triggers(pins 1,2,3,11,12,13)in pairsto the gm coil, ?and ground the gm boxdoes that make sense?i'm about ready to make this upgrade and i've been thing about this for a while.i mean i do have spare rb20 ignigter and harness, but i'm checking evey angle.
The issue is that the stock ECU is not strong enough to drive the coils directly. This is the exact reason for having an ignitor... think of the ignitor as amplifying the signal from the ECU so that it is strong enough to drive the coils.rudedrift wrote:thanks. i've been looking and looking. the guy with the hal-tec said that system used the same trigger and didnt use his ignitor.
but, what if i used a rb20 ecu and a switch for the intake cam?
What size fuse would u recommend? 30A?240z4u wrote:The relay is there to cut power to the coils when the car isn't on as far as I understand it.
I wouldn't use over 10 ga wire. Your not supplying 80 amps of current. Also, that wire should be fused.
Guys,Bringing this one back up. I have been having many issues with coilpacks and I had the coil and wires and a pigtail laying around from when I bought this botched Rb20 swap.a1cpunker wrote:
this might be a stupid queestion but what kind of relay is the 4 prongs relay? can you post a Part #? or is it one of the 4 prongs on the car. thank you sir
Which engine is this for?And yes, technically. But here the majority of states (Provinces for you, my Kiwi friend) do not do emissions testing.Faustini wrote:Cefiro Coil loom... the previous owners butchered my rb coil pack loom, anyone able to help me connect the 3 wire corretly for my 5th cylinder coil pack (or 2nd cylinder.. its the one 2 from the front)
Is it true you guys in the US aren't allowed to register RB powered cars for road use ?
I have a question about this Z32 ignitor application of the buick coil retrofit. In the pic above, it shows the center wire from the 3 pin plug being GROUND and going to the ground on center of injector side of ignitor and going to earth.DriftX wrote:This is a simple wiring diagram for those who are running the z32 ignitor and wish to wire up the gm/buick coil conversion. This also eliminates the small 14 gauge wire to control the coil, rather now this includes how to wire up a relay and using 10 gauge wire directly feeding from battery.
