After i sprayed some seafoam into the plenum through a vacuum line, the car started missing badly on idle and making popping noises from the exhaust. I turned up the idle to 1k now so it does it less frequently. What can it be? its a rb25 neo. While driving the car is perfectly fine though.

Well that makes spraying "seafoam" a pretty useless use of time and money....

Maybe it dislodged some carbon and is caught in a valve?

I personally would never use the shit.

Rev car heaps and see if that fixes it

Or spray some other magic cure in there.

Why did you use the cleaner in the first place? What problem did you try to fix?

They aren't really a substitute for actually fixing the problem.

I would pull the plugs and see what they are like,they might be covered in shit.

i did it just to clean up the plenum a bit since i never cleaned it before. Checking the plugs is gonna be a pain because i need to take the throttle body off . The car even misses on low revs below 3000 i realised.

fixed the problem. The place where the spark plugs sit was flooded with coolant, especially the first cylinder. The plugs were also dirty so i cleaned them with a wire brush and contact cleaner. Car is running perfect now. Thanks for the help guys

      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 🍻
