I won't need a bigger turbo to get to 200rwkw don't you worry about that

hmm, coincidence, i have just spent half the night pulling apart half my engine o check, clean and re-gap the plugs. On the r34 standard gap is 1.0 mm. The current plugs in there are NGK-R PFR6G - 11. Does anyone know which plug this is?

They looked like they were put in somewhere in the last 2-3 months [just before i bought the car] but i dont know if these are just copper ones or not? Or if they are the right heat rating [is it the 6 or 11 :confused: Any help on this would be good.

I have re-gapped them to approx 0.8 > 0.85mm as the car seems to run a bit rich [stock ecu / car / etc]. I am not sure if the 34 should be the same as r33 spark plugs either. Damn finding info on the 34 is a nightmare atm

Thanks guys...:( [sorry about the thesis]

NGK-R PFR6G - 11

That is NGK's part number code (as you know)... This is how you interpret it:

NGK - Manufacturer

PFR - Platinum Spark Plug

6G - Heat Range 6

11 - 1.1mm Gap.

I use to think that the R34 & R33 RB25DET's used the same heat range plug standard (6's) It turns out that the R33 engine has a 5 heat range standard & R34 a 6!

Both are a 1.0-1.1mm gap factory.

you are still wasting your money, trust me! Just go and spend $3 per plug on coppers. They are much better for the line, as platimuns dont do jack for performance (in fact, in some cases they were worse), and you will need to change them before you know it (b/c of line running so rich!!!

Search around these forums on this. It has been brought up many times, and you can find heaps on good info on this! Always do that before asking a question, as many subjects raised have been covered many times....

I was lucky coz my partner was selling a brand new Autronic CDI for $750 which was cool to match my Autronic ECU. Usually I think the CDI is about the $900 mark retail and then you need it installed. The spark is HUGE!!!! I recommend a CDI to anyone who wants to run high levels of boost.

I'm now leaning towards the copper plugs coz from what I've been told and researched, copper is a more conductive material than platinum or iridium. The only problem is that you have to change your plugs more often.

What kind of tuning do you need? Give us a call at the factory on 9512 7591 and ask to speak to Gerald or Nigel. They should be able to either help you with the tuning or point you in the right direction.

so it doesn't matter if i run copper/platinum/iridium, as long as it's a 7 plug?

what's a CDI worth these days leewah?

I do have a shit cold start at the moment as the car needs a tune (got HKS gear... no one in melbourne to tune it!). So i'll get new plugs to go in once it's tuned

You guys did my Twin Plate OS Giken Clutch... remember, i've got all the HKS computer gear (PFC-FCON, FCONV, VPC).

I'm still looking for the software, which i think i'm gonna be hard pressed to find.

How often should you change the copper plugs and which model number? BCPR7E, is that the copper NGK's with a heat range of 7? or should i get 6... cos the car isn't really given a bootfull all the time, it's a daily driver. So if i get a 7 i don't want the plugs to foul up just from putting around (would a good full noise run clean them or do you have to do a couple of hard runs?)

Ahh yes, I remember being told bout all the gear in your car. Good luck finding a tuner in Melb. Maybe if you asked BD4s, they could help you in some way. They are the official distributor of HKS in Aust.

Because I've had spark issues recently before the CDI, I went through about 3 sets in 4 months coz of fouling the plugs. Fouling copper plugs was a much cheaper option than platinums. I reckon most people around here would use either the 6 or 7. If your not going to be driving hard that often, I would say the 6 would be a better option. Also the 6 would give a better cold start.

Cleaning the plugs is simply a case of hammering the car stupid for bout 5 mins. That should clean all the charred stuff off. If that fails, WD40 and sandpaper does wonders. On the other hand, $3 for coppers plugs may save you all the time and effort :D

yeah i've spoken to BD4's... they basically just said "nup, we are the only ones that do HKS tuning". I've been given a name of a guy who does performance car tuning around SE Asia, so hopefully he has all the software. The hard thing will be catching him when he's in Australia!

I think the $3 option is better than the effort of cleaning them!!! Probably takes about about 15-30min to clean them all properly, i'd rather chuck in some brand newies and save the hassle!

    • perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML
    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
