Hey.

Just a quick question about installing the catch can on my RB20det.

I have a aftermarket turbo and top mount manifold and the usual line which people plumb into is no longer.

Heres a quick picture of what i propose to do.

Is it correct? Is it the right breather to go off. Reason i went this one is it has had nothing on it at all since the new intake and everything had been on.

What do yous think?

Your intake plenum looks like a low cost option for those of us that want front mounts without the mass of intercooler plumbing.. what sort of money would a setup like that cost?? Isn't the fuel feeder/return for the injector rail mounted on the end of it? how did you get around that?

You can run it like you have in your diagram no worries, This is how mine has been run for 3 years and it works well.

Just need to make sure the catch can is sealed, as if it has a vented filter, you will get a massive vacum leak at idle.

Also you will need some sort of filtration in the catch can, steel wool in a stocking works well, otherwise it will not work

Alternatively you could just block of the PCV valve and run two hoses of the cam covers to a vented catch can, but I found this to be a bit smelly for everyday driving

Yer ive heard about putting steel wool into the catch can. it might be a bit hard with mine as the only real opening would be the drain hole down the bottom. Ill see how much i can shove into it though.

Cheers

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      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.
