i was at the drags tonight and when i took off i started getting lots of smoke from under my engine bay due to a melted catch tank hose (dont use the ones they give you!).

when i got to the middle of the track it felt like it was running on 5cyl and i had alot of smoke coming from behind the car (oil frying on my manifold).

i opened the bonnet and there was oil everywhere, one of the catch can pipes burst.

my oil pressure is fine, engine temp is fine, knock is still reading low.

so what could it be?

my spark plugs are a bit black..

ive got no smoke coming out of my exhaust, and no oil in my catch can.

thanks guys, i could realllyyyy use some help.

maybe the extra fuel fowled up one of my spark plugs more than the others because i think i got a boost spike.

try either removing any step-downs in the piping or removing the catch can altogether and see if things return to normal.

A friend with a 33 had similar issues after installing a catch can and it turned out to be the step-down that were causing the problem.

don't strip it down if you haven't tested it.

You said that oil was burning on the manifold. That's what the catch can is for. storing oil. If your pipe melted, it's just oil coming out of the tank and burning on the manifold.

The fact that the pipe got melted doens't matter. You can run the engine without any hosing connected to the cam covers.

      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 🍻
