Coils For Rb25/30

[cactus]

Looking at using a different coil set up on my 30DET. At the moment, I am running a series 2 head with standard coils. This has been fine for a while, but just after the drags a few weeks ago car started having issues on full boost, and now I am certain its the coils breaking down. I don't want to waste my time/money with splitfires (again), in my opinion/experience they are shit.

Anyone have any suggestions as to what I could use? A workshop over here runs Hyundai Sonata coils on a 1000rwhp+ 2JZ, so was considering looking into this. Just wondering if there is anything else out there that is known to be effective on any RB.

Cheers,

Matt.

Yeah these are known to be good.

I was running an AU falcon coil with wasted spark & leads on my old 25/30. Worked OK but was only a streeter.

Best option is the XR6T coils - cannot think of another car that will create the cylinder pressure that these cars do and without spark issues.

Just make sure you get the upgraded BF coils which are designated by the last two letters AB not AA. Have used these coils upto 1400nm of torque. All you need is 2ms on time for proper saturation - which will also be fine at high rpm.

How do you go with fitting them to the RBs?

Can you fit leads to them easy enough?

[R31Nismoid]

Splitfires are identical to OEM - Just cheaper...

If you keep killing coils it honestly sounds like you've got other issues, not the coilpacks themselves...

Simply changing the entire setup won't neccesarily fix it either which is another point.

If you are over 380-400rwkw then you need to pickup the HKS DLI box and wire it in.

Good for well over 550rwkw then

You would have to make a mounting bracket up which would sit the coils up higher - ie away from the heat. The xr6t coils have a slight offset on the plug boot but the xr8's run a straight boot, you could probably get way with either as you would probly cut the boot in half so a slight offset wont be an issue. They just run a spring inside the coil boot from coil to spark plug so you could even use a boot off something generic.

I've tested theses coils on numerous occasions and are able to fire up to 35mm gap - which is as far as my coil tester goes, so firing a 1.1mm gap at 20psi on an rb30 will be a walk in the park!.

These coils are also used as a multi stike at idle on the falcons to help with emmissions - so if your ECU permits you could also do this.

Hey,

Been off-line for a bit.

The first set of coils I had (standard items) I killed as a result of wiring on my behalf. This was sorted, but instead of putting in standard coils, I used a set of Splitfires instead. The Splitfires lasted about 8 - 12 months, and then one started to fault (i.e. it would cut in and out, so on warm up the car would only run on 5 cylinders). After a while a second coil started having the same problem so I got rid of them and started running the standard coils. These are the ones which are now playing up under boost. I dont think its any other issue other than, the current ones are 10 - 15 years old and are finally giving way.

I'm not sure whether to get a brand new set of Nissan coils, or try something else.

Hi Matt ,

try URETHANE SEAL COAT ,i did my COIL PACK`S & No problem`s ,

There is few POST`S ON here so best of luck & hope it will helpout,

Cheer`s Chuckie.

a 10 year old set of coils with 140,000 km's on them had better power readings than a set of 6 month old splitfires, they are NOT THE SAME COIL!!!!!!!!!!!!!

do these require an ignitor like S1 setup or will they work with out like S2 setup?

[J'z-R33]

LSx coils, inbuilt ignitor, easy to wire in and pretty cheap.

heres a DIY guide..

Every single setup with splitfires i can think of would beg to differ on that point, my own car included.

most oem coils by 140,000kms 10+years old are getting tired and start to leak but there are those out there that still perform perfect. as for the splitfires you speak of, tough luck, but you cant judge every splitfire based on one uncommon experience, as r31nismoid put it there are far more instances of the opposite occuring to contradict your statement.

i think many forum users have been over this many times and confirmed, splitfire/yellow jackets/red chinese/oem coils all deliver seemingly identical performance. i believe its just a matter of getting new coils no matter what sort (2nd hand just not worth the risk IMO). and unless your very unlucky, they should perform well for a long time.

what ecu are you using? if it has an adjustable dwell setting then any coil will do.

wasted spark is good but your are halving the dwell time with that option. if in doubt cdi is the way to go.

of the waste spark coils i have used, rx7 s4 is the best. then 1ggeu then mitsu gto tt coil pack. of them the mitsu coil had the easiest mounting options.
