Hey Guys,

Got a problem with my car atm that is doing my head in. It's a Series 2 R33 GTS-T with the only mods being a full exhaust.

Basically what is happening is when the car has reached its normal operating temp, (about half way on the temp gauge) when i stop at a set of lights for example it will idle fine for a minute but then the revs will drop from say 7-800 down to around 500 so the car feels like it is going to die, and then pick back up again.

Also when it is doing this if i put my foot on the throttle just slightly the car will almost stall out before coming back more aggressively to try and stay alive.

The car has been lacking its usual power lately and seems to be hesitant at certain stages throughout the rev range.

I have done a full wet and dry compression test, the dry coming up as 155 - 157 across all 6 and the wet as 175-176 across all the cylinders so i know thats all good.

Im considering taking it to someone with a cable to plug in and see if any error codes are coming up.

Would be a great help if anyone could suggest anything.

Cheers

BOV leak and not fully closed? Throttle position Sensor up the poo or loose and its moving. There only little screws holding it.

Just a few thoughts. Not sure if it will help you.

:D Doobs, that fixed the warm idle problem! car is sooo much smoother especially when i come on and off the throttle.

Still having problems getting full power i think i need to check on my afm though i only cleaned it a few weeks ago... Car seems hesitant to pull hard through the rev range :)

      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 🍻
