Splitfire Coil Packs For Rb26

Gday, just after a few (experienced) opinions here.

My car has been off the road for several years now, and im getting enthused to finnish it, so im not sure if im just looking for an excuse to spend money on an unnecessary upgrady or not.

Ive got standard ignition with standard coil packs on a built RB26 with an Autronic, hopefully putting out over 300KW at the wheels (The engine isnt assembled yet).

Is there any sense in getting splitfire coil packs or do they provide no advantages over properly working standard ones? Ive never had any ignition problems, but then ive never experienced this power level.

Should i spend $500 on something more worthwhile??

Thanks,

Shaun.

The coilpacks are worth evry penny if you ask me. i use them in combination with a spark amp and they havent failed me yet. i switched to them as i was beginning to experience spark issues that didnt stop after re gapping the plugs. but i run 450 kw on a daily driver. I think they can handle quite more than the stockers. a friend of mine who has a 26 in his R33 GTST using a T3/T4 hybrid ball bearing turbo pushing 450 HP cracked 3 of his stock coils, and if im not mistakin these packs can handle more heat.

yep- the stock ones will die eventually, and you may even see problems at 300rwkW if they are old

splitfires are a good cure, but lots of people use the bosch coils and leads approach these days, which works out a little cheaper, but doesn't look as neat.

Splitfires are only useful is the stock coils are stuffed/dead.

If the stock ones are fine, then there is absolutely no reason to change em.

There are oodles of cars making over 350rwkw using stock ignition without an issue

yeah splitfires are good, but only if your coils are dying

Also, if you don't have lots of money to spend, i'd look at wasted spark

round $140-$160 for a complete setup and sell your old coils to fund it

Parts needed:

VN Coilpack or Buick V6 coilpack from the states round $60-$80

VL or VN commodore lead pack round $80 for 8mm eagles

then wire it up to your old coilpack loom:

Just make sure you label the wires before cutting them

gncoil9vn.jpg

you cut the lead just after the ignitor, only on the 7 pin plug, leave the 3 pin, that is your timing and power plug :D with the black coil loop

in this order Left to right when looking at ignitor:

Ground, 6, 5, 4, 3, 2, 1

Connect wires 1/6 2/5/ 3/4 together and put one of each up to the top posts

You can now cut the timing wire mentioned above and bridge it onto the 1/6 post

When doing this, mark the front of the coils with the coil numbers, i scratched mine on with a screw driver because i was in a rush

Now for the bottom posts:

Take the power wire which is in the middle of the 3 point plug and bridge the power to each post on the bottom row of the coilpacks

Then get your spark plugs, use the longest up front, all the way to the shortest for the firewall cylinder(6 i think? or is it 1)

then mount the coilpack on the firewall, make sure no wires are out, maybe insulate the back of the coil or put heatshrink over the wires first

Then plug it in, take the ground which you haven't touched on the 3 point plug and reground it(has a bolt holder ground thing on it from factory)

Then make sure all coils and leads are in the right holes :P and start it up

Should work perfectly

if you have any missing, double check the wiring and cylinder leads

I have a set on mine(Splitfire)....only because I had some of the old ones crack.

I have the cover off(To allow ventilation)...ignition module earthed...

Tape up all the loom.....tape up your coils.....only change the set if you start seeing problems..

But if you have money...buy them ASAP....cause your pocket is on fire.

Ha Ha, my pocket is definately on fire.

Thanks for all your opinions, i think ill spend my money on the engine build instead (oil control maybe), and then replace the coils when they cause a problem.

Im using an Autronic SM4 without CDI

The best proven coil-pack is new genuine nissan, but if your on a budget like most coil-pack buyers splitfire are your next best choice and WAY cheaper. Best set-up is a new std set with an amplifier.

Splitfires are the same as stock, so how is it any better? :action-smiley-069:

I cant say ive heard of splitfires failing any "quicker" than a OEM coil... come to think of it, most splitfires are still working. No dead one comes to mind at this stage but then most people have only been using them for 3 years or so

yeah how many splitfires are going strong after 15years? we sell ALOT of splitfires (100's and 100's) and you would be suprised how many are DOA (dead on arrival) or play up not long after the warranty period stuffs up (dont get me wrong ive had them in 3 cars, current has a FET set... same thing). look at some top level drag cars like the HKS, SAURUS.. PHENIOEX use NEW std coils with amplifiers like twin power etc with no dramas at all....

veilside's R32 GTR, 8 second on radials runs standard nissan coils. so they can't be too bad IF they are working properly. if they fail the only viable option is splitfires as the nissan ones are far too exxy for most to handle.

Ah but now we are talking Japan where prices may indeed vary?

      Front LSD Quaife , how streetable ?- QDF3L Owners

      By joshuaho96 · Posted

      Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?

      The FD RX7 is the best looking 90's JDM car

      By Kinkstaah · Posted

      in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.

      I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.

      If they just called it the "Mazda Tiffany", it would have been spot on.

      Yup but for me its the HR ! Cut my teeth on the old holden 6s in the day ! And here's me thinking in the day it was also the 300ZX and the Mitsubishi GT3000 ! All, as well had good lines, but always seemed to need finishing off, style wise.
