Hi!

I'm putting my RB20DET together, and I'm about to do my timing. Ive heard of people talking about BTDC. My question is, are you talking about the harmonic balancer being 15 degrees BTDC? not have all the marks on the timing belt line up? I dont understand this. I dont really wanna get this wrong, I want the motor to go in shmic!

Please help!! Photos would really help if anyone could!

When putting the timing belt on, make sure all the marks line up. When you set the ignition timing with a timing light, set it at 15deg BTDC. If you are confusing cam timing and ignition timing i would recommend getting a mechanic or someone who knows to give you a hand at theis crucial stage.

When assembling an engine, everything is done with the crank, and hence the harmonic balancer, at TDC.

The only measurements that should be BTDC are ignition timing, which requires the engine to be running.

      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%?

      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.
