hey all i got a tophat style forward facing plenum, i run an rb20 in my s13 and one of the main reasons i got this plenum is to elimate alot of my intake and intercooler piping as there is no way for me to have a flush sitting bonnet with my setup.

So in short i need to know if i can just tap into the intake plenum anywhere and put the vac lines to it that were on the old manifold, for example ..

- Brake booster to intake plenum - > can i just tap this into anywhere in the new plenum ?

- the 2 x coolant lines that come out of that little block on the old plenum - > what do i do with these? can i just loop the lines together ?

- The pipe that goes from the old plenum to the rocker cover - > can i just tape this anywhere into new plenum? or can i go to a catch can instead?

any other info would be much apreciated, im thinking the vac lines would be easy to sort out but i have no idea what to do with the coolant ones.

ive attached 2 photos, one of the bottom of the intake plenum that shows some already threaded holes in the bottom wich i can tap into for some of the vac lines

and the other photo shows the old plenum with the little coolant block thing with 2 x pipes on it.

as long as its not the turbo water feed then I think its one thats ok to block off. If you look through the RB25 Greddy install thread then you will probably find most of your answers.

cool ill have another proper look tommorow, that greddy install page doesnt help with specifics, its for an rb25 and its also not a tophat plenum like mine, and some parts are very vague, ie : the part where he blocks a hose off with a bolt and doesnt say what the hose is and what it does etc.... but ill look through it some more and see if i can spot anything that will help.

im thinking i may have to drop the plenum of to a shop and get some ports welded onto it.

      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 🍻
