Anyone in Sydney had a Cobb access port upgrade. If so please give us a run down on the benefits and gains. Any downsides (other than the obvious warranty thingo) and who installed it for you and for how much? Also, did you need to upgrade anything else (i think a midpipe is strongly recommended). That about covers it I think. If there is no one in Sydney I would also value anyone elses oppinion on it.

I'm in Sydney and have the Cobb AP - with three Willall tunes. E85, E85 drag and 98 tunes - provided by Martin. About 385awkw. It really is as good as per the thousands of posts and threads the world over. I think i ran a 11.1 @ 128mph on the 98 tune and 10.7 @ 132mph on the E85 tune (full weight) at WSID so compare these times to stocker numbers and you can see the benefits are pretty clear. Can't think of a downside really! For E85 you will need upgraded injectors and fuel pumps.

The COBB is the 'must have' mod.

with the new version including TCM support you would be mad to look at anything else.

many people have run either mail order tunes or custom tunes with impressive gains reliably on both the street and track.

do it!

Well i bit the bullet last Friday. The blokes at CRD did a great job.

Wow what a difference. The most noticeable thing so far is the mid range torque increase. No matter what speed or what gear, when you drop the foot it just pulls like a bastard.

      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 🍻
