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)

    • Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.
    • They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.
    • I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
    • Either way he still need those style of spacer to go into the manifold because the photo he currently has is not going to work 
    • You can just get the injector bosses, which allows top feeds to fit. He can use the same injectors without issue, like these (another option): https://rocketindustries.com.au/af59-2210-rb25-fuel-injector-inserts     The Racework ones look a bit better: https://www.nzefi.com/product/raceworks-lower-injector-mounting-boss-kit-for-r33-rb25det-s14-s15-sr20det/   You could also just get a similar kit like the Radium one by Plazmaman: https://plazmaman.com/product/nissan-rb25det-r33-billet-fuel-rail/?srsltid=AfmBOoogfYq49X0fu2Wdbf8yOf6zt9egyPAif_gn3Qr3G8hzAphhTgOkO70
