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.

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.

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.

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.

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...

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.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
