yeah they will be fine at that power level, i would expect somewhere near 80% duty cycle, somewhere near there. just make sure you have a good pump to keep up and it should be fine.

fuel injection is irrelevant of turbo, boost pressure etc. it purely comes down to how much is being induced and how much fuel you need to maintain the levels and make it combust

the s15 injectors must be manual JDM ones.

australian s15 injectors are only 370cc like the R33 stockers

Hi Paul. With the stock R33 injectors what would you think

they are capable of. Obviously with the supporting mods

such as fuel pressure reg, pump etc. Also im currently

using the walbro. Do you think they are that bad? Im

after around 230-240 mark. Should i change to a 040?

Thanks. :D

Nope. ADM is 440cc aswell. They are not 480cc as everyone says because they were measured at a different pressure.

You should get about 345 rwhp out of a walbro.

They don't pump as much as a bosch 040 or 044.

I don't think they're bad at all. I know one guy on here who had a walbro that sucked in it's filter. And I've heard a lot of people have bought dodgy chinese knockoffs sold as walbro's. The knockoffs don't pump muh at all. (Just amke sure it's real!!)

But I think they are a good replacement for the stock GTST pump - although not huge.

      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 🍻
