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 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 :(

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.

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.

:(

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.

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..

    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
