hi all

my engine light came on the other day, but went away next time i drove the car

then came back, then went away

i think it's now here to stay

so i pulled the code ( http://www.skylinesaustralia.com/forums/Ex...p;hl=paper+clip ) and it came up 21 = ignition system

that's an issue with coil packs, right?

i have read through:

http://www.skylinesaustralia.com/forums/Co...ml&hl=coils

but i have a few questions:

1) if i'm running stock everything, should i be OK to grab a set of second hand stockies?

2) if not, how do i tell which one(s) is faulty? pull the rocker/coil cover and diconnect 1 by 1. if the idle doesn't change, then that one is faulty?

3) most importantly, how do i change the coil packs? is it a pretty easy DIY? i've got limited knowledge and tools :laugh:

4) if i go new, what's the latest and greatest? Splitfires still? JJR? other? are they still ~ $500-600?

thanks guys

I wouldn't be replacing my coils on the strength of the warning light - I would expect some concrete defficiency to make itself known first.

Second hand stockers should be fine but i haven't seen any good way to test them. It should be possible to build some kind of a test rig but its beyond my electrical skills.

The Yellowjackets seem to be as good as the Splitfires but the red ones are allegedly inferior.

R34 GTT Neo are the same

doesn't list R34 GTT either :ninja:

hmmm, might get the car checked out then instead of blindly replacing the coils

cheers

I got Splitfire from a ebay trader for $550, it solved my sluggishness, gave me a huge power boost and stopped a slight shudder. (also cleaned the injectors)

The Splitfire model number for the RB25Neo is "008"

Now i can floor my accelerator with ease!

    • Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
    • 9" wheels are a little too wide for a RWD 32. They can fit. People have put R33 GTR wheels on 32s for years and years. But they are a very tight squeeze. This has been known for about 30 years. As I said - there is no difference between a 17 and an 18 in terms of what will fit. The rolling diameter needs to stay about the same as stock - not very much larger. If you increase that, you will start to have problems. If you increae rolling diamater at the same time as yo increase width, you will have problems earlier. as 9" wheels are pushing the boundaries already, you would need to be careful with tyre choice. I would put 8.5s on the front of mine, but would expect problems with 9s.

    • Diagnostic flow for a code 21 says check signal at the ECU pins, on a voltmeter of some kind it should read 0.1V at idle, 0.12V cranking, 0.15-0.25V at 2000 rpm. Check each coil such that +1, -3 is infinite or very high resistance, -3, +2 should do the same. (-1, +3), (+3, -2), (+1, -2), and (-1, +2) should all be somewhere between 0 ohms and high resistance. If you trace the path from the coil pin all the way back to the ECU in the diagram the resistance you measure at the coil vs connected to the harness should be pretty much the same. 
    • I have an elite 2500 running an adapter harness on an rb25de neo r34. I took the butterfly out and removed all that junk. But I also went Plus+t at the same time. The butterfly thing works in reverse to the boost solenoid on the Gtt if that makes sense
