how much u pick it up for pus? is it the ones thru BATMBL?

i rkn i need to do my front end exhaust stuff...

my system is buggered... got stock fronts, 3" cat, 3.5" pipe which splits into dual 2.5"pipes and goes to twin barrell mufflers with 3.5"tip each. and one of the pipes has a hole in it and its muffler has its glass packing all fallen into the muffler.

gayness!

Hiflo cats, 3" cats, to be honest does the dollars spent really justify the power gain's? Granted your exhaust will only flow as much as the smallest part is but does $250 spent on a hiflo cat really make that much difference? I'd love to see a before and after dyno/test on this. I would think the difference would be negligable.

Got a 3" dump fitted today at Turbo Exhaust Centre in Wetherill Park, Sydney. The guy makes them in-house and claims that he supplies most major performance shops in Sydney.

Very nice piece of work. Fully mandrel bent and beautifully crafted flanges on the turbo end as well as at the cat end. Bolts straight up!

I highly recommend them. $330 supply and fitted.

I got a 3" Trust MX Front Pipe + 3" Catco Cat + 3" Trust MX Cat-Back. But I'm still using standard dump pipe which connects the std turbo to the MX front pipe.

My idle is stable now at 750rpm, not jumping up and down, so your problem may not be because of the ECU. But try disconnect your battery, pump the brake pedal a few times to discharge any electrical residue to reset your ECU and see how you go.

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
