Hi there, I have a hr31 and I'm looking to replace the igniter and coil pack loom. When I search the part number from the igniter in my car it comes up with a 300zx zr32. I read that the zr32 and red top igniter are the same. Is this true? And if so will that work on a silver top engine or should I buy a different one? Any help would be great i just want to make sure I'm buying the correct thing. 

(I'm not sure what loom is in the car but I'm assuming if the igniter is for a red top then its the original one also has the red top ecu)

As GTSBOY has said, I would also take the opportunity to upgrade to integral igniters. If you want something on the cheaper end; use newer S2 coil packs like spitfires or OEM. 

Cheers. 

With putting in coil packs with integral igniters do I just remove the current igniter and put in the different coil packs and section of loom to suit?  Thank you both!

Yes, essentially. The original wiring from the ECU will currently go as far as the igniter, then the coil loom runs from there to the coils. When you go integrated coils, you basically have to patch in the ECU wires that would have triggered the old igniter to now trigger each coil's igniter (so straight through) and clean up the power supply and earth stuff. There are guides available, but the fine detail depends on which car you're doing it to. They're mostly the same, but don't go trusting wire colours - trust terminals.

Also as far as I can tell it has splitfire coil packs but do only specific ones have the igniter built into it?

Splitfires are direct replacements for whatever the engine originally had. RB20 and earlier RB25s were all dumb coils with the external igniter pack. Later RB25s and Neo25s have built in igniters. They don't even physically swap from engine to engine, because the coil mounting brackets change. You can see what Splitfires go with what engine by looking up the model number (say SF-DIS-001) and it will tell you what it suits. There are several models across the RB20-RB26-RB25 group of engines.

Splitfires are a good easy swap and used to be the only game in town. They were probably never really any better than the OEM coils - they were just available new when OEM ones were old, burnt and cracked. Someone has done you a favour by putting them in there, and if you do follow the recco to replace them to banish the igniter, at least you can try to sell them for a few bucks to offset the cost of the upgrade. It's not as if you likely need to be replacing your coils. But if you're going to pay for a new igniter.....I know what I would be doing.

That makes sense thank you so much for your help!! I'm definitely going to look into getting rid of the igniter it was something I wanted to do anyway but wasn't sure if it was to much of a hassle thanks again

      Mistakes were made, my R34 Story

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
