In all reality you can go a long way with std rods and pistons but honestly, if you pay someone to do everything properly you don't save a lot. Have a set of standard rods checked, new bolts fitted, closed and honed, pin bushes replaced etc and see what it costs. Then compare that to a cost of Spool rods, you might save $350-400, if that. Forged pistons will set you back maybe $700 more than a set of cast stock ones, maybe as little as $500.

Compare the price to re-ringing a set of 20 year old factory pistons and doing nothing to the rods and it might seem a big cost but if someone's going down that path the argument is pretty null anyway, the difference between doing it properly with cast pistons/stock rods and forged pistons/aftermarket rods is small. They might cost you $1000 extra but over the total price of the engine, it isn't a huge percentage for the piece of mind it gives you.

Well said, couldn't agree more.

What have you done to the "stock" crank?

Cleaned, crack tested, no knife edging or lightening etc, just a oil pump drive and balancing, so stock as in not an aftermarket billet or knife edged or lighted crank, just as pretty much everyone else runs their RB30 cranks, nothing special about it at all.

Buy some insurance here..

I will be using it on my new motor...always a chance at getting a bad batch of fuel. Very hard to keep all bases covered on a servo fed street car. Advanced ECU's like the Motec M800 and Autronic SM4 will also enable you to engage over boost, fuel pressure, EGT, AFR, etc protection limits...the more insurance the better.

PS All for using a stock bottom end...to cheap to worry about it eventually breaking "if" you have the ability to rebuild yourself.

7 years, 1.5 bar + 100hp NOS, 450wkw with nos, low 10s, 7200rpm limit, stock bottom end with new rings and bearings only.

the power your after is effortless on stock pistons, its all in the tune.

Hi rob, remember me ? I have your stock rips bottom end under my 26 big sump tomei pump, custom 2 stage catch tank setup, ati balancer. Currently making 658hp atw been running for 3 years roughly now

Is yours still going ?

Mine has had some more work done, JE Pistons, Argo H beam rods, Jun cams, Blitz 4" intercooler etc and it's now a bit over 600 RWHP.  Same crank, head, block, oil pump, water pump and a lot of ancillaries, oil cooler, radiator, fan, BOV's etc.

      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.

      Blue slip

      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.
