Hey guys getting a tune on my car soon and got recommended to put iridium plugs in it. Just wanting to know what you guys use what you think best option is and your opinions it an Rb25det with work I'm hoping to be pushing around the 400hp mark.

Thanks for any help.

Iridiums are fine, they are just harder to gap down. Some say you will gain a little power from going copper but the trade off is you may need to change them every 10,000k's or so.

Iridiums can last 80-160,000k's if you keep them cool. They still melt if abused.

Iridiums will still lose some effency after 10-20,000 klm.

If you service your car every 5,000 klm put in fresh coppers every second service, on every other service pull the plugs and clean the electrodes with some fine emery paper and regap.

I have always done this and never had a problem even running 380 @ 22 psi.

Iridiums are designed for lazy people who do not service their own car, the less plug changes over the 100,000 saves some money but will effect performance.

I want all my killer wasps all the time.

The $30 or $40 dollars every 10,000 klm makes good performance sense to me.

I don't think we've talked about this topic enough so I'm going to disagree with all of you.

Please continue

I know this topic has been done to death but if you find my method flawed please enlighten me as I am always open to opinions that may prove me wrong.

I may be old but Im still open to some learning.

If I say yes will the thread continue?

A yes with a reason and I shall never be seen in this thread again.

A no with a reason and I still wont be here again because I have said what I believe to be correct due to many hours of searching and my own prior research on spark plugs and correct gap sizes.

:P .

Thankyou for clarify this issue, its good when a subject matter expert helps out a newbie with a quick and to the point explanation, its good to see them help people with their wealth of technical know how, I would say its even good for business.

There is a thread a week about spark plugs.

Answering the same question 50 times a year doesn't help anyone. It just adds to the problem. There was a thread only last week and it was answered quite well I thought.

And yes I was being sarcastic but I'm like that sometimes. The people that know me would usually laugh, those that don't might think I'm a prick. I don't mind.

I help the ones that I can help, I don't help the ones that don't help themselves by searching first.

To answer your first question, there is no flaw in your method. It's sound advice and I feel that the question was answered appropriately so I made a very clear sarcastic remark to make a point. I just didn't know I would be arrested for it :D

      Definitely didn't put a N/A cluster in instead? The speed sensor (location) is different in both cars.... I think. This will obviously stuff things up.

      Nah not the throwout bearing, it's something internal. I already replaced the throwout bearing. Mechanic misdiagnosed my car and thought it was a spigot bearing, went to another bloke who said it was an input shaft bearing. (I replaced everything when I pulled out the gearbox but didn't open up the gearbox.   In this video at timestamp 6:05 : Mine has the same sound  min

      It is definitely to space it out and away for clearance during compression, and possibly for spring clearance to upper arm. That latter would only be true for springs that are same-ish diameter to stockers, and so that probably doesn't apply to Teins or most other coilovers.

      Yeah, a mechanic who knows these cars told me even if I get a brand new gearbox the noise will return but will be less noticeable. I've heard someone also they this noise came back after 3,000km on a new or reconditioned gearbox. It is pretty f**king annoying though just hearing groaning most of the time lol. I wonder if an aftermarket input shaft bearing would fix the problem or how they are built.

      All RB gearbags, especially the big turbo box, have rollover noise. Mine certainly does. Always has. Sometimes is worse than others - no particular idea why, although it is probably temperature related. I have smurf jizz in mine and have had to have it in there from the first day the box went into teh car. It simply would not select gears with the engine on, on day one, with normal oil in there. And so, the blue stuff has probably ruined almost everything synchro related in the box. But it has taken 12 or 13 years to get to the point where I simply must replace the box. It has become increasingly baulky of late, which might be symptomatic of the way I've been driving it, as much as anything. I shall have to make some corrections when teh new box goes in. Input shaft bearing noise will decrease with clutch pedal pressed because the drive is removed. But yes, more often than not noises that work like that are associated with the throwout. It won't matter either way, new box will mean this one can be relegated to the parts pile.
