Rb20 igniter

[Eva_hr31]

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)

Z32** sorry

Take the opportunity to get rid of it altogether and put coils with integral igniters in, along with an upgrade in spark power. Use Yaris coils for a cheap smaller upgrade, or R35/Audi type coils for a big fat upgrade.

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!

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

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.

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
