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.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      Could it really happen......

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
