Thanks.

So what exactly does it do?

Im looking at a motor that doesn't have this, is this bad.

Sorry for the stupid questions.

How much to replace? etc..

it gives spark to your coils, if it don't have this it wont run unless running a really good aftermarket computer that has this built into it.

Found this, it explained a fair bit.

My mate has a late series 2 skyline and his motor has the holes at the back of the cover where the module is suppose to be.(with brackets etc) he has the wires setup differently going across aswell. My 97 stagea has the unit and Im sure it has a S2 motor in it.

It doesnt seem to be doing much.

Is this ok. Should he go looking for a replacement?

no... I don't think so.

I'm Guessing your stag has an earlier model 33 RB25DET spec engine in it. (96 model?)

Most S1 Stag's have S2 R33 engines in them - which do not have an ignitor module seperate - it is built into the coilpacks.

If he has a series 2 R33 then he doesn;t need one... he should just have the holes

Check FAST for your relative part numbers - or alternatively.. ahve a search for Splitfires.. you will notice that there are different splitfire partcodes for different 33 spec RB25DET's... one for the old model and one for the new.

Yeah you are right mines a late 96 and he has a series 1 and should have one.

The reason I ask is when I looked at it after he got it back from a service it looked like it was missing.

There is still part of the support bracket on the module that is just hanging there! Dodgy!

I told him to get back to the mechanics and get it fitted back on properly, maybe somewhere else.

The car seems fine. Would this have done damage in the long run?

umm not really right....if its a S1 motor and the ignitor is missing it will not run at all. So if its runnign (even badly) its not the problem

This is what is missing. And is a R33 S1.

The car starts rough but still runs fine.

But they have done some extra wiring between, I will post a picture.

I suppose a Splitfire super direct ignition system would be of benefit (upgraded coilpacks and module),

but he has been quoted $120 from a wrecker replacement and $215 (genuine) new from;

Any input would be appreciated.

When my mate got his 100k service they had the cover off to replace plugs, seals, belts etc. The incompetent f*#ckers looked around the workshop this morning but couldn't find it and then put up the argument it wasn't there.

Makes me laugh, because from research and what people have told me it is a part which is needed for a series 1 because these are built in with the series 2. The bracket and whole black box isn't there. It looks like they bypassed the module and have joined two connectors across the cover. One of the modules support brackets and screw is still attached to the cover. It is evidence of it originally being there.

I reckon they were in a rush and forgot to put it back on and then lost it. The wiring loom setup looks different as well. The car always starts rough but then runs fine at idle and on the road. Would this cause any long term damage? Still the question remains-should he go and replace the igniter module or upgrade to a better direct ignition system? It seems a lot of people do this, especially close to the 100k service mark. RB coil packs seem to be trouble, causing loss of spark and misfire.

The reason I ask is I might look at doing this soon. Anyhow this is the wiring which seems to bypass the whole module-is this ok?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
