R34 Gtt Problem

Hey Guys,

I just got a new boost controller, nistune and a walbro fuel pump installed today.

Once I warmed the car up and started driving it I have realized that there is a bit of a problem, when I take off the car is jittery? its like the power is cutting in and out, but once I am above 2k - 2.4k rpm the problem is gone.

The car is also idling a little lower and a little rougher. If I hold the revs at around 1.5k rpm the revs will slightly fluctuate and even though I am slightly accelerating it will continue to fluctuate revs around 1.5k rpm until i have accelerated enough that it goes up straight to around 2.5 - 3k rpm.

Does anyone know what the problem could be? or ever run into this problem? The car was running fine before and has new splitfire coilpacks.

Thanks a lot for any help.

Mate just do the fuel pump rewire, Im sure that will rid u of the problems- mine was running like arse at and below 3200ish rpms, jerking, power loss, idle and startup was crap, blowing a bit of smoke at low revs sometimes, when Jez rewired the pump to get direct 12V, it was a different car altogether

      Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉

      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 🍻
