Is my planned setup overkill?

Wow you guys really went into depth ! Was out for a few days lol. From what I newly learned and understood is a “head drain” is essentially to relief pressure from the crankcase gases going up thru all the engines holes and making it easier for oil to drain back , correct ?

Now I do have one fitting on the extended sump already. Is it necessary to make another one? One line tee’ d off to the sump and to the intake.

Them the other like to the covers ? Would this way work ?

still need to buy some other bits like the crank collar and the correct size oil restrictors. I’m in the states so it’s a little more difficult to source rb parts out but I think as we got more rb cars imported people are really getting more into them. Anyways my solid goal is to make my car as reliable as I can to have as much seat time as I can. Now need to buy some more maintenance bits and turbo and manifold and we’re off to go. 

Thank you everyone for the input !

 

 

P.s I’ll give these sard injectors a chance this season and see how they act up. But will be getting some modern ones later on. Just on a budget lol.

When you can I would definitely consider getting some Bosch 040 injectors, those will be a lot better for spray pattern, atomization, and accurate flow control as long as you stay within ~OEM parameters i.e. ~3-4 bar differential fuel pressure, ~12-14V supply. NZEFI sells them for a pretty fair price.

If the goal is to help relieve pressure you probably should route from the top of sump in the spot where crankcase pressure is highest to a PCV valve then T into the plumbing back to the intake. I suspect the reason why most people route the line into the head is actually to use the PCV valve, otherwise you will start pulling oil into the intake at idle due to high vacuum.

If you are going for full drift I would seriously consider a dry sump system. Wet sump works for street cars but if you are going to be at high revs and pulling high Gs you will ventilate the block at some point even with the best wet sump setup possible.

Yes you need to ventilate the crank case but you need to employ an air/oil separator or catch can or both. Read say the last half of the oil control thread to see what people have actually done to achieve comprehensive oil control. A dry sump system is ideal but an expense that can be avoided even by dedicated drift machines with the proper measures.

      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.
