He meant that all cars respond to different cam gear settings differently...even with standard cams...so tuning IS STILL REQUIRED to get some quantitative results...so your mistake there...

That said...i've read up alot about these before i had mine done and in general most guys ended up with between +1 to +3 advance on INLET and -2 to -6 retard on EXHAUST...thats a starting range...the rest is up to you...

get it tmmrw now (hoping), timing belt and water pump changed. true, but still you will need it tuned. i doubt any gains in the top end will happen, at most might get a little extra midrange? any who tell you when i get it

Did you end up getting these fitted and tuned? interested in results...

Heard from a few tuners the best results on RB20s are seen at IN + 3 and EX - 6 but that being said, all motors are different and react differently

I just had my car on the dyno over the weekend and we ended up advancing the EX side as it liked it better and picked up a bit more power through the midrange and top end, when he retarded the exhaust side it lost a whole heap of power

I'd probably suggest you let a tuner do it just so they can recheck timing and making sure its not pining etc

but is the +3 and -6 of the crank ? or is it of the cams?

      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.
