My 32 gtr starts and runs excellent when its cold, but as soon as it get's hot say maybe 10mins into driving it feels like it drops a cylinder and runs rough as hell. It blows black smoke when it does this, and continues for about 10mins then clears up, then goes back to the same thing. Ive changed the plugs and the coil packs, was thinking it could possibly be the igniter. Has anyone come accross this problem before?

Hey Ragnrok,

I have just come from this exact situation, when i finally installed all of my mods cams,injectors, cooler everything when we put it on the dyno my car ran like shit after 10 min when she cooled down bingo went away, i spent hrs pulling of coils changing plugs earth straps etc,etc,etc ,anyway make it short i changed the IGNITOR and presto she ran perfect once again just like i remember it.

Borrow one of someone just to see if it works then you know your problem, this problem was really bad more so when i was driving on the street than the dyno.

I am 90% sure the ignitor is your problem seems common on our older skylines now parts are getting old and we are pushing more power out of what they ever had to do standard.

Hope this info helps you.

Cheers,

Dave.

I'm having the exact same problem aswell. I went into Nissan today, and apparently a new igniter costs $700!

What do you guys think about doing something similar to this?

I will be hooking my car up to the consult tomorrom at Nissan so hopefully i can shed some more light on the situation. Nissan also said that you can send them away to be bench tested to determine exactly if it is a faulty igniter. Has anyone bothered to go this far?

And lastly does anyone know what igniters go for second hand?

    • Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.  
    • I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.
    • The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?
    • I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.
    • I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
