I heard the jap model S15 (manual) injectors which flow 480cc can fit as a direct swap into the rb25det, can anyone verify this? If so would it support up to 270rwkw with fuel regulator? I have all other supporting mods.

Apparently other engines to share this style of injector are the RB25DET, the 1JZGTE, 2JZGTE and the VG30DETT.

Yes they are a direct fit. So are USDM Ver 5/6 STi injectors (a little easier to find, usually go for about $USD150 per set of four). The toyota "J" injectors are low impedance, so no good without a ballast resistor. Mazda FD3S primary & 20B injectors will fit with Sard type collars.

So you indeed have some choices !

I looked into doing this once, but I would have had to buy 2 sets of injectors (non of the wreckers would split them) then I was going to get them cleaned and flow tested and use the best 6. Total cost was around $600 (for second hand injectors) - I then decided if I was going to pay that much I would rather spend $700-$800 for new ones rated at 550+

where did you get them for under $800?

      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 🍻
