Hey,

i'm just wondering if anyone has used the NGK Iridium Spark Plugs in their '33?

If you believe the brochure they're a lot better, but I've heard people say they're not worth the money - just wanting to know if anyone has had any experience with them or anythin similar - good or bad?

Thanks Guys!

Well my dad's GTR had problems with the platinum plugs fouling at anything over 1.2bar. we fitted the iridiums and they made a massive difference. much smoother and no probs at high boost. im going to get them for my GTS. i dont know if it would make a huge diff on a low powered car like mine. but it made a big difference with his.

Thanx for the speedy replies guys! does anyone know what the NGK platinums go for at say Autobarn/Repco? - don't wanna get ripped off!

also does anyone know the part number for these plugs for an R33 (NA)?

considering ive got an NA, what gap width would you reckon i should run them at?

Thanx for your help again

hey price is about $19.50ea

I dont know what u should gap them too. i know for turbo RB engines its 0.8mm but on the packet the iridiums say not to change the gap because the tips are very fine and fragile.

I gapped them to 0.8 anyway and they have been pretty good.

Yeah I know, a lot of things are overkill...but they spin a whole lot of crap about how much better the expensive stuff is, I guess people just believe them, a lot of us being those people!!! :P

I was quite happy to go with the cheap copper plugs until he explained to me why the Platinums were better...made sense to me so I bought them!

like i said earlier i have iridiums in mine at the moment. and im happy with them.

i paid $21 each i think, sure they spark stronger due to the finer tips. but i dont expect to see any big performance gain.

but the good thing is i wont have to change them for another 100K k's or so. (NGK quote 150K actually)

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
