Hi guys,

Well its been 5 months since i started the Rb26/30 build & its about time to fire her up! :thumbsup:

I've got a few questions for you all, if you could give me some feedback i'd appreciate it:

1) Oiling: What process should i go through to make sure theres good pressure upon starting it (i.e priming the pump, turbo's etc) and wats the best way to go about it.

2) Will it be alrite to start the engine with just the dumps on, or should i wait until i get the front pipe made up? Reason i ask that one, is i'm putting the engine in at my place, and then towing it to the exhaust shop for the front pipe to be made, and then its off to the workshop to get tuned.

That's all i can think of now, if theres anything else i should know, please let me know :laugh:

cheers

Shane

1. Disconnect the CAS, and crank the engine until the oil light goes out, and the gauge shows pressure. Then you know there is oil around the engine, and you can get oil pressure. Then reconnect CAS and fire away.

2. Even at idle, an engine with basically no exhaust makes a hell of a racket (I know, I did it when I fitted a little L20ET to my R30).

When i get my new engine in this is what I will do.

Connect the fuel line that goes to the rail back to the return line to the tank (no fuel getting to injectors)

Disconnect the CAS

take the cam covers off - pour oil over both of the cams (not too much just to soak them a little)

take all the spark plugs out and turn the motor over untill you can see the oil light either turn off or flash a little (some oil lights stay on and do nothing)

keep turning the motor over without any compression or spark or fuel untill you can see lots of oil activity in the top end. once this is done you should be right.... (put rags around incase you get oil splashing)

are you looping the fuel line to stop fuel going in the motor???

if so, when the cas is disconnected your injectors wont pulse, so it will save you looping the fuel line.

about the exhaust part of things..

noise levels, obviously theyre going to be huge and its gona run a bit rough but who cares, wont cuase any probs.

its a bit bodgy but i drove my car down to the exhaust shop about 3kms away after a rebuils with a dodgy peice of dump pipe, sounded like a truck and went like shit but who cares if your just firin it up!

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.

      The downside to that is that the cost of everything, particularly labour, is significantly higher here than it is over there in the Disunited States of Slavery. You can hire 3 tradesmen over there for just the Ranger Raptor allowance of a single 3rd year apprentice over here.
