Found this guys website when reading this thread on r31skyline club

http://forum.r31skylineclub.com/index.php?topic=36055.0

Basically it replaces them with a system that runs wasted spark, you can then mount it on the firewall and run external leads. Even if you get him to do all the rewiring and soldering yourself it only costs you ~$230 for a set with new leads. Another option would be to use an AU falcon coilpack and get someone to rewire it.

The specs look good, was wondering if anyone has done this with success? Im looking at doing it as I have a redtop rb20det which if I go splitfires I will need an adaptor loom as well which will cost at least $700 for the lot.

old news but it does indeed work.

i know of a few ppl that have done this conversion due to their stock coils farking out.

Cure all misfiring problems, no longetivity issues with the wasted spark issue?

I have a remote mounted AU coil pack on a redtop RB20, although with an aftermarket ecu and have had no dramas with it.

I did however have VN items before the AU and they failed miserably, all 9 times.

VN Items are KNOWN to fail. Even the VN boys upgrade them, even on a stock engine. They're a poorly designed coil pack. If you had researched them a bit, you could have found this out. The VP S2 onwards packs are a MUCH better design.

I wasted ~$400 doing a bosch coil pack conversion and STILL had a miss at anything over 1 bar, even with a .6 plug gap. Eventually I sold the setup to recoup some of the outlay and got a set of splitfires.......haven't had a problem since.

Splitfires can be had for <$550 delivered these days, so I don't see the point stuffing around with something that MIGHT work. Plus the external coils are a pain to mount in the engine bay and look messy.

I would add that using coil leads from the coil packs to the spark plugs simply adds another 6 electrical joints likely to cause problems. Coil on plug design was done for a reason, RELIABILITY.

:ermm: cheers :O

I emailed this guy and didnt get a response.

I ended up doing some hunting around and found that the coil packs he use are from a Buick Grand National V6 Turbo.

I got them on ebay brand new from the states for less than $AUD50

Got an ignitor from an r32 as I have a series 2 rb25 and the ignitors are in the coils.

Wired it up and away I went. No more idle problems.

I know him and where he works.. have to tell him people want his coil setup.

No idea why he wouldn't respond.

I personally find stock coils very cheap to replace and have always been fine for me. Maybe one will break down from time to time.. i would just get another one.

True but wouldnt relocating to somewhere aside from the furnace between the head be a bonus? I mean plenty of cars run leads without issues.

I found out I can get a AU coil pack brand new for $70, leads will set me back ~$60 and what $70-100 to get an auto electrician wire it up properly for me. This vs $585 it seems like a much cheaper option and leads are cheap if for some reason they did break.

Do you think that the splitfires + adaptor are honestly worth getting at more then double this price?

Some things to think about;

1. The standard coil packs are designed by Nissan to live in their environment ie; Nissan knows the temperatures between the cam covers.

2. Nissan (and all the other car manufacturers) went away from remote mounting coils for reliability issues.

3. If you mount coils designed for chassis mounting on a vibrating engine, they will fail.

4. If you mount the coils on the chassis, then the leads will flex as the engine twists and they will fail.

5. If you use coils designed for vibration mounting and mount them on the engine, they will be subject to the same (if not higher) temperature variations than the standard oils.

6. The temperature between the cams (where the standard coils are) is controlled by the water flowing though the water jackets of the surrounding cylinder head. This means an even temperature once the engine is warmed up.

7. Remote mounted coils on say the firewall at the rear of the engine, are subject to far greater temperature variations. This is not good for the life of a coil.

8. Using a coil pack designed for an engine that revs to 5,000 rpm on an engine that revs to 7,500 rpm is asking for high rpm misfire.

9. Do you really think a Ford designed coil is going to work better on an RB than a Nissan designed coil? Why is a Ford coil set $70 and a Nissan coil set $490? Is it possible that the Nisan coil packs might just happen to be 7 times better?

People blame coil packs for all sorts of misfire problems, when the truth is the standard coil pack is a very reliable and efficient device.

:O cheers :)

i agree with SK and as an auto elec i replace heaps of failed AU coil packs. everything he has said is right. if you look ate everything on a nissan it has been designed very well. take an R32 GTS-t the brakes on these things are grate for there age but every one wants to upgrade them. like everything people decide to upgrade. they upgrade it because it is worn out and they say they were no good anyway but if they restored them to like new they would find they are actualy good.

plus leads every where looks shite

Yeah cheers for the info guys, Ive gone ahead and ordered some splitfires as I want to do it right the first time, and its less hassle.

The adapter replaces the entire cabling loom as well so all new cables and wires which is good as the old ones are all hagged and brittle now.

Its amazing what a set of good pads will do to the r32's brakes. Mine have a better feel than any other car I've driven. Extremely predictable and easy to control if they lock.

Don't forget about the added resistance throughout the system due to the 3/4 of a meter long ignition lead.

lol.

What adapter are you talking about exaclty? The splitfires only come with coil packs. No ignitor or loom.

How much are we talking, and are they new from Nissan? :)

    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
