Hi I drive an r32 gtst RB20det and when I rev up above 4000/5000 rpm there's ALOT of pooping noise and Im losing alot of power. I've tried replacing my coil packs and also air fuel meter but that didn't solve the problem. There are oil in the pipe conencted to my pod filter could this be the source?

Thanks

yeah I'm using 1.1mm atm... so I guess I should go try the 0.8mm?

was the model NGK BCPR6ES08?

also does the oil in the pipe connected to my afm and pod filter mean anything?

I dont think you can get the BCPR6ES pre gapped to 0.8???

If your after a pre gapped plug then look at R5671A-8 which are (depending on mods) or go with the 6ES and gap them yourself to 0.8

Blow by is when air and moisture is forced past your rings into your crank case, on higher boost it'll usually force oil in there too.

Are you running a catch can???

i had the same prob with the rb25.

boost leak-maybe but it should misfire all the time not at higher rpms...is the misfire getting worse or staying the same

coil packs-are you sure you swaped with good ones

spark plugs-can always use new ones

i would def try to change the plugs first unless you have good coil packs that you know are good.

my main prob was the coil packs along with the plugs and the boost leak

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
