ive heard of people using VN series 2 coils and AU falcon coils with leads to suit

the leads most likely will need to have a boot on the end where it joins the sparkplug (to 'plug' the hole, just like the coil on plug setup now has that wide rubber flange thing)

go to your local Auto1 or repco and they should be able to help you out (specially if you bring your old coil on plug setup)

dont get VN series 1 coils as it is a single big coil pack, where the series 2 is multiple packs

either that or get some splitfires for the VN series 2 as they are about $75 and some decent leads to suit

do a search in the how to section for wasted spark, its a very every well written article with what you need what you can buy and how to do it, read it then you will have all you need to no to be able to do it

ef coilpack=$105

ef top gun 8mm leads=$30

sparky to wire it up=$50-100 max

ignitor=$80

say roughly $300 worst case..

splitfires=$580 odd from memory double the price?not for me

i know which one is better, ef can run longer dwell then splitfires= better burn= more power

will not over heat due to being able to run away from the cylinder head.

only downside is fitment which isnt hard and the splitfires only thing goin for em is that theyre bolt in. ef coilpack from start to finish max 2hrs.. being an rb25neo would prob have to source a ignitor which is hard.

plenty reason to use an alternative

you'd think that if the coilpacks are such a stupid idea that nissan would have picked up on it instead of manufacturing their rb series engines for over 10 years?

i just replaced mine with spitfires, i figure if the originals lasted 10 years, than the new ones will surely last my time

oh well each to theyre own, nissan enginers a motor that works for the best price as mass production, dont think they do it for whats best for the motor, i realise your thinking behind your purchase, think of this the reason coilpacks fail is because of excesive heat. e.g being bolted to the cylinder head then coverd up. ef allows to remotly mount the coilpack and run a longer dwelltime = more power...

    • GTSBoy on your suggestion on another thread I had a look at those injectors and ended up getting them because of the quality.  Got the expensive ones.  
    • Hey guys been looking everywhere to try and find the correct gtr hood latch support part number but only found the first half and when I search with that number it sends me to an r34. The first part I found was 62515. If anyone could help me with the rest then I’d really appreciate it. Or if there’s some alternative hood latch support that would work even better cause I can’t find any for sale. (Searched on upgarage, partsouq,buyee,rhdjapan) 
    • If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
    • I have a heap that i have collected if you want some authentic ones still. Pm me if your interested!
