Sorry to hijack but I just got myself a set of plugs I wanted bcpr6es but could only get bcpr6es-11 now I'm running stock turbo with 10psi and aftermarket ecu soon to be 12psi should I regap to .8 or just leave 1.1

Andrew put coppers and changed the gap on my sparkies on my n/a 34 .. the car always makes a popping sound and shakes rather violently at idle now .. feels very weird, I called him up and he said he changed the gap so it would misfire at idle rather than higher up in the rpms, but it never did misfire higher before :S

but it may be the second hand OEM coilpacks we put in to replace mine ..

I have no clue, gotta take it back to andrew sometime soon :(

They will work on both R33 GTS-T and R32 GT-R? Same plugs?

work fine on all twin cam RBs

Jonno34, you basically want to run the largest gap you can without getting any misfire under load, every engine is different so it takes a little trial and error. might be worth learning how to do it yourself as im sure its not too cheap paying a workshop $100+/hr

Cheers mate, ill search around and try to learn how to do it soon!

so the misfire at idle was due to the spark plug gap? i was worried it was the coilpacks and I got myself a faulty set :( their expensive things and id really hate to have to buy another set ...

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'

      D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.

      KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.

      Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.

      Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
