alternatives to standard coilpacks?

[kwazza11]

well i've had a couple coilpacks die recently and a couple people telling me the setup on the rb motors are prone to failure due to copping all the heat from the engine and dont generate a very strong spark. so i've started considering alternative spark setups.

has anyone had much experiance in using different coilpack setups with the standard ECU? such as using external camira/bosch coils and leads and setting it up as a wasted spark system?

I think Splitfire coilpacks are around $600 for a set from nengun

I think it comes down to luck.

I bought my 32 on a genuine 67,000km's just over 2.5years ago.

It has since clocked 166,000km's with no coil issues. Yet!

I agree with Joel, our R32 GTST has 170,000 k's on the original coil packs, the GTR has 142,000 on the original coil packs, the Stagea has 102,000k's on the original coil packs. The old R32 GTR still had its original coil packs and it is close to 200,000 k's now.

Personally, I haven't had a problem

are the split fires any good compaired to stock?

My standard coils were working fine, but with higher horsepower applications then the SplitFires are the way to go:D Series II GTS-t coils are pretty crap though, as they have the modules inbuilt, and are much more prone to problems.

same as the 34's then

I'm sure they would have improved the coil design by the R34 models.

I meant that ours have the module inbuilt as well.

My coilpacks have failed and I'm waiting on splitfires.

666Dan has also replaced his coilpacks on his 34.

Maybe just a luck of the draw

Bugger:( The Series II's always struggle to make more than about 330rwhp without running into spark issues, so we swap them for Series I coils and module or Splitfires.

I left the the R34 GTT of the original list because it hasn't done that many k's. It has 265 rwkw and it's coils packs are std, maybe I am just lucky with them.

On the race cars we use a Motec CDI with Mercury outboard coils packs, because they are designed to work with CDI's multiple discharge.

how many km's are on it now?

I'm fast approaching 130,000kms

Mine had to be replaced at 70k

Seems the continual heat is a major factor in the coils dying, and having the inbuilt modules won't help either.

[GTR-Ben]

I have also had little to no trouble with coils on any of mine or other Skylines I have worked on.. and some of these are daily driven 10s cars that run the stock coils.

[GTS-t VSPEC]

GTR's are much better, as there igniter module provides much stronger spark. ND4SPD was running stock coils and module when it made 500rwkw, so it's more than doable. Pity they didn't make the GTS-t's/GTT's as good:(

To avoid coil pack failure I took the upper belt cover off and used a hole saw and file to make a tear drop shaped opening to the cam belt area. I then opened up the little ventilation fins in the rear section ( fins vent into the coil pack area / valley ) so I now have air flowing through from the outer most part of the fan, through the hole I made, between the cam pulleys, through the fins and down the valley taking some heat away from the coils then venting at the rear of the valley cover. ( Hope all that makes sense ).

Should work on any RB I would guess.

I've yet to finish the job off with a nice piece of mesh to stop any nasties getting in but it seems to have worked as I've never lost a coil pack in my R32.

[666DAN]

As Ed said my ones died ~80,000Ks back when it was N/A and only proved annoying at idle, when the turbo went on at 110,000K's it was all too noticable....the current R33 ones I'm using seem to be OK though (fingers crossed)

I did actually consider setting the packs up in a corner of the engine bay with spark leads going to the cylinders.

From what I've heard, the splitfires are the go.

There was an R31 with a worked RB20 I saw after the Drift Nationals with 6 older style cylindrical ones on a plate on the firewall with leads to the plugs. Not sure about the electronics behind the set up unfortunately..
