Hey guys

Reeeeall stupid qusetion and i cant find it no where

What is the exact sparking mesurement for the spark plugs (RB20DET)

Iv found n bn told 1.0mm

1.1mm

0.08mm

I had them all at 1.0mm and it was missing as i was coming on boost fairly mild

took them out made them bit smaller roughly 0.9mm and its running a hell of a lot better now top end high revs is missing???

Sooo im thinking its smaller again!

Cheers KISIN! Yeah i found that, but the answer that person gave "Ummmmmm i reckon..... roughly 0.08mm" (WOW convincing much)

Which yeah i wanted to ask yous n find out EXACTALLY the messurement

0.8 not .08 sorry typeo!!

and yeh standard for RB25s as well.

Hahah thats what i ment as well!

0.08... That would be a very tight spark :P (haha... tight.... :thumbsup: )

With an N/A engine 1.1 is the standard and that is what most plugs are out of the box.

With a force inducted car you get away with what you can but most people will run around the 0.8 mark.

Also be careful with platinum plugs (which i will never use unless i own a car which is a bitch to change plugs) not to touch the electrode as the platinum coating is only a few microns thick and if you push a screw driver in their trying to gap a plug you will ruin it.

    • Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏
    • Hi, Marek here 🙋‍♂️. I finally fulfilled my longtime dream - recently bought Stagea and now waiting for it to arrive in Poland. There's only few of these in my country, and one of the owners  recommended mi this forum as a source of all the info i'd need since now i own one  so here i am.  
    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.  
    • Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
