]Just wondering if anyone knows if there is a difference between the turbo and non turbo blocks. Im aware the pistons are different, but is there any other difference. If no one knows can they tell the measurments of the stock rods of a rb20det. And the crankshaft. Reason being ive got a non turbo block that i want to rebuild with forgies ready to put into a r32 so that its fresh, clean and strong. Im obsseive when it comes to reliability.

And also is there any other pistons you can use.

Please help guys and girls im desperate!!!!

I have the same blocks in my race car. They run 10.0:1 compression with the different pistons, but the rest i beleive is the same for the turbo block assembly.

10.0:1 is great for a street car, but limits your available boost pressure.

Valve springs could be of lesser tension than a turbo motor.

It would be good to really know for sure if the bottom ends are the same as the turbo engines.

Yeh thats true about the oil squirters, but I think they are only a benefit if you go circuit racing. It's not a real big issue in a drag racer.

They can be fitted with some slight machining to the N/A blocks.

      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.
