Hi the other day i was giving my car a bit of a workout and the orange check light came on a few times. I just asumed my car needed a service or does anyone know what else it could be or what it means???

Anyway i want to give my car a service myself and my mate is trying to tell me if i buy the iridium or platinum NGK spark plugs im going to need to get them spaced otherwise they won't work right and will sound crap. Is this true and how can i space them??? Its for a R33 GTS-T.

Thank you in advance

They come at a 1.1 gap (not sure about 0.8) ... platinums can be bought in either 1.1 or 0.8 .....

I run at 0.8 (heatrange 6) on brand new splitfires and high boost just to ensure the spark doesn't arc out.

Do a search there is plenty of threads on this topic ... btw nissan recommends 1.1 & heatrange 5 for a stock vehicle (guessing that is with coils with no issues either)

i bought iridiums from supercheap about 5-10 000 km ago and they sold me the wrong heat range, and the wrong gap size. mercury motor sports told me that the iridiums that i was sold where for a non turbo stock r33. ill have a look for the part numbers for the new plugs, coz my car is running wicked good now i got the right plugs.

P.S if anyone knows someone with a N/A r33 that needs my old plugs plz pm me, :P lol

u may need to re gap em if the car is modded....... u can get a gapping tool any car shop..... im pretty sure they come gapped already for stock tune.......better take it to a performance joint they can recomend what they should be at.

LoL,The first tune shop i took my car to charged me like $50 for the Apprentice(i assume) to bang them on the ground with a hammer to re-gap my plugs to 0.7mm.

it worked

im told you can use cheaper alternative plugs which are only like $4ea. p/n BCPR6E i think they're copper but was told they work well.ill give em ago for my next service/Tune

Cheers

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day

      RH9 R32 GTR Build Thread

      While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.

      Are you 100% sure this isn't tune related?

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      140-150 across the board. At this point hoping the grounding harness fixes it. My grounds are all tied to the chassis and none to the battery. For SR and KA that’s never been a problem for me but had a few other guys here and Reddit who told me RB really like a very solid ground setup tied to the battery so going to try that next, I’m stumped if that doesn’t do it. Never had a car have spark and fuel and not fire off before. Only thing I can think is the spark is intermittent/weak because of grounds nothing else really makes sense at this point

      I am having close to the same issue. Can you help me with what wire you grounded to get your pump to trigger?
