Wasted Spark Ingnition

[BADR33]

hi there,

this mod is suitable for rb20det, rb20de, rb25de and det(as long as you have an ingnitor pack on the cam cover) can be done for series 2 rb25s but you will require an ingnitor pack.

i have a cheeper alternative for all you people out there who keep losing coils and dont want to fork out big $$ for spitfire coils.

what you will require:

6 spark plug leads that are a suitable length to reach to where ever you decide to mount the wasted spark setup. i used champion steel ingition leads part number CH6106S for a holden commodore vs&Vt 3.8ltr but i suggest you buy them individuly as you can get the lengths much better as i found 2 of them are a bit to long

the replacement coil pack is what i was told is a buick(holden) tridon part number TIC032

side cutters,

soildering iron and solider, or crimpers and the correct crimping bits to clip on to the coil pack.

heat shrink

and between 1-2hrs to do.

step 1:remove coils and coil loom from the car. and decide where you want to mount the coils.

2: strip the coverings off the wiring so you can see where and what wire each one does.

3: lable the pink wires so you know what wire is for each coil. then cut off near the plug

4: for r32s you will need to make sure you dont cut off the ground wires from the ingnitor pack(7 wires) to the other small plug(3 wires) next to it. r33 has (6wires and 2wires so there is no ground wires to deal with)

5: you will need the white power wire from the 3 or 2wire plug as that is the power wire for the coil pack.

6. group together the pink wires in to 3 sets. 1 and 6, 2 and 5, 3 and 4.

7: i suggest you lable the front of the coil pack as you attach the wires to the coil pack as to save on any confusion later on.

8: attach the white wires to the pins showen on the pic. it doesnt matter what side of pins you use as long as all the white are on 1 side and pink are on the other side.

9. mount the coil pack in your engine bay. make sure that the pins on the back are not touching anything. i folded mine down and put shrink wrap over them just to be safe.

10: put the spark plug leads on the spark plugs and the coil pack in the correct order and plug in ingnitor pack.

11: if your car had dropped a coil then you should reset your ecu. but reset it anyway to be on the safe side.

12: start your car. if it doesnt start check that the leads are on the right plugs as its easy to accidently put (3 and 4) on (1 and 6). if its r32 check that you grounded the ground wire.

otherwise just check that you did wire everything up correctly.

i will try and get walk through pics if i do the conversoin again hope this helps

Hi,

I have an RB25DET series 2 in my car (ignitor in the coils)

I got an R32 Ignitor, just wondering if you can confirm how I need to wire this up?

I presume I should run the power from the R33 loom to the Buick coils, the R33 gnd to the gnd on the coil side of the ignitor, cyl 1,2,3,4,5 and 6 wires on the R33 loom, to the corrisponding wires on the ignitor.

Hi there.

strip off the inuslation off your coil pack loom and you should see what is happening. dont cut the plugs till you have labled what wires go to what spark plug. take photos as you go incase you forget somthing.

pink is the power so you put them on one side as i have. white is signal from the ecu to spark.

you dont need any grounds for the coil pack. as your using r33 coil pack loom you dont need to worry about a grounding loop that r32s have as they have an extra wire on the r32 ingnitor and on the other little plug has 3wires instead of the 2 that r33 have.

Have you given any thought to the resistance of the coils being different, which will affect the dwell period as well the current limiting. Electronic ignition systems are capable of dwell extension and also current limiting. The resistance of the coil will vary both things.

no, i am just following what others have been doing. this set up must work as it is used on 90% of the top rb powerd drift cars in NZ from what i was told by the guy who sells this as a made up kit.

i have some links to other websites with the info. this dus improve idle, acceleration and i found i got a little bit more fuel econamy and power.

and the guy who sells the set up

http://gdz1la.kol.co.nz/prod01.htm

there is also guys who use mitsi VR4 coils and other kinda coils.

[Nozila]

can you give a rough idea on how much these setup approach cost? i want to do this on my series 2.

[MANWHOR3]

These have been done many times on skylines and they do work. Won't be expensive at all.

I actually have a link from r31 skylines.com where they install it into an rb20.

If you want, I actually have a coilpack and leads that I was going to use on my car, but I was given a set of splitfires for christmas. I'm not looking for much.

[Nozila]

if i can adapt it to my series 2 rb25det motor. hit me with a pm. =)

[BADR33]

all you need for the series 2 swap is a coil pack and mb the coil loom. im not sure on the series 2 coil loom will plug up to the coil pack as i dont even know anybody with a series 2 engine.

my set up cost me $140 all up from memory. i probly could have done it a bit cheeper if i had bought leads seperatly. plus then they would all be the right length...

you will need an ignitor pack as the series 2 don't have them.

i was telling my mechanic mate about this and asking what other coils you could use. he said that the coils off a vt/vx commodore would be good, for some reason which i can't remember but will find out. but he also said that they have a built in ignitor which would make them good for series 2 r33's. i'm going to try to get a hold of a commodore coil pack and plug in the next few days to start working on a conversion and a how to.

[Nozila]

that would be great. keep us posted. but im still dont 100% understand the how this works. im assuming the ignitionleads plug directly onto the spark plugs?

[BADR33]

yup the ingniton leads go on top of the spark plugs. makes changing spark plugs nice and easy especialy if you dont have the coil cover on.

im going to do the conversion on my mates r33 gtst in a couple of weekends. ill take some better pics hopfully this time from start to finish.

its the same as running your normal coil packs. except that 2 plugs fire at the same time. so the plugs will be doing 2wice the sparking they would with normal coil packs. the main idea of this is to get the coils away from the heat of the engine as that what kills the rb coil packs.

i have had people with series 2 rb25s pming me and they have almost got it sorted using a r32 coil pack. im just waiting to hear back from him about how it all went.

[MANWHOR3]

many people have got this working using an rb25 sI motor ignitor/rb20 ignitor. It is an easy mod.

I Can't find the thread now, but yeah, they just wired in the ignitor like how it is in the wiring diagram in the service mannual.

[Nozila]

Having a quick read for the last 20-30mins, it seems that for series 2 rb25's I would need an ignition from either a r32 or r33 s1 with the r32 being the more favourable. So this means, I would need the wiring look I would presume? The one in which fires the coilpacks...

[mad082]

if i get this commodore setup going it will do away with the need for the ignitor pack as the commodore coils have the ignitor built in. also the good thing is that a full set of msd coils for a commodore are around $300, which is a lot cheaper than $900 for splitfire skyline coils.

but it is looking like it may be a week or 2 before i get a chance to have a try as i'm off to the test and tune day at willowbank this weekend.

[MANWHOR3]

Or if you wanna do it even cheaper, buy my falcon au coil (including leads) $50

Buy an rb25/rb20 ignitor for $20-50

That's 100$

[mad082]

yeah but wouldn't be rated at 40,000 volts like the msd coils are.

[BADR33]

my pricing is brand new leads and coil pack through repco but at mates rates..

pfft ford.. who would want a ford part on there car.. lol its bad enough we have mitsi parts running our engines

[mad082]

i get trade price at repco anyway, so that doesn't worry me.

i was just wanting to try it with a commodore system because they have an ignitor built in so it would save having to chase around trying to find 1.

[mad082]

and i wouldn't be starting with msd coils. they would just be a possible upgrade down the track when the others couldn't handle the job.
