You are supposed to replace the clutch too?

How is the Nismo fuel pump?

yes if it is standard and i imagine the nismo one is expensive and not much better

CAS is Crank Angle Sensor and TPS is Throttle Position Sensor.

The engine won't operate correctly with the stock ecu... you will need to re-tune the stock ecu or use a piggy back etc.

I use a simple rpm window switch sold by JEGS in the US to controll the VCT.

Change the fuel pump.... by now it's at least 15 years old if it's the origional. You should be able to find a suitable drop in replacment from nismo etc... or even a low km GTR pump.

If you do go ahead with the swap, double whatever budget you work out... trust me. Also, before you install the new engine get it checked (you don't want to go through all this just to find out it's a dud) and replace ALL the service items- belts, timing belt/idler bearing, clutch etc... I'd also advise replacing the water pump and oil pump for a N1 pump with a crank collar if your going to modify the new engine.

The rb20 gearbox won't put up with alot of torque and abuse... go with the rb25 box.

What is a crank collar and why change the clutch?

Speak to a mechanic that can do all of this stuff for you, you are just going to end up shit creek if you have to come ask here about every single item all the time.

I like learning about things so that I will know what is going on.

    • 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!
    • 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.
    • 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.
