It's been 6 months now since I decided to endevour the difficult task if r&r of the shit rb26 stock turbos.

Delay after delay from wrong banjo bolts to dropping bolts down my turbo. Wanting to do everything right so I won't take it out again anytime soon!

Anyways I have finally completed the task!

Cars been sitting for 6 months without starting and I would like some opinions before I give her a crank

Long story short should I change oil with mineral to flush then drop again for synthetic or just leave oil and put new synthetic oil in after its at OT

I have changed the coolant so it's fresh

I will be taking out the spark plugs and dropping a bit of oil down the piston tops to help guard against removing surface rust

Changing spark plugs while I'm at it

Checked all hoses and lines.

Now finally the oil is Dam filthy. Wouldn't feel happy with it running through my engine so a change is a must.

But the head/cam lobes is pretty much dry from sitting around

So I was thinking of dropping the oil cold and finding a cheap synthetic oil to flush out the system of any possible stupid previous owner debris before the first start!

And then draining the cheap oil and filter for proper synthetic oil? This way the head gets more lubed up and the old oil gets flushed out easily? And hopefully it primes my new lines? :)

My problem: is it alright to use mineral oil to flush out the old gunk (for < 100km ) cause synthetic oil seems a bit of a waste to use as a complete flush, or am I better off just biting the bullet and let the cam lobes grind on the lifters for a few seconds and change the oil and filter normally after that?

Wanna reduce metal on metal as much as possible :D

Why not take off the rockers and oil up the cams?

ive managed to strip 1 bolt on the intake cam cover because of the stupid screwdriver head bolt.

mustved been locked in by the gasket glue or something.... wouldnt even budge with an impact driver >.<

rest of them came out fine

change oil.

disconnect ignition module.

crank until oil pressure(should be able to get some).

start.

If it doesnt build oil pressure, will need running speed to get it.

mine was a complete fresh rebuild.

sitting for 12 months.

this is what I done.

you dropped the old oil cold and dropped new oil in straight away?

i just opned up my coilpacks and found oil, i was shitting myself until i touched it and it turned outto be brand new oil in some dirt haha

guess previous owner wasnt steady with his hands when putting oil down the cylinder LOL

Anyways back on topic!

Cranked like 2 times thn my battery died :(

Also found out I wa running bkr7es

Is there and advantage to this spark plug compared to bcpr7es?

Also my attessa kept making a sort of rubber runnin on glass burbling sound when the battery was low and the torque gauge would twitch to 1 and attessa would turn off ? And start up again after 5 secods? Is this normal? Accumulator f**ked ? D:

the plugs are standard, not platinum.

just means you cant leave them 100k.

the attessa is probably having fits with the low battery voltage.

charge it up, and try again.

i think both bkr7e and bcpr7e are both copper/standard plugs which need general maintainence?

is there comparisons between them?

Battery is on a charge tonight, will try again tomorrow :)

And anyone ever flush their 26 out with mineral oil and then changedback to synthetic oil before?

aparently mineral wont go through small cracks like synthetic does?

I'm fair sure it's just some acronym used by NGK about the spark head. Platinum plugs have a different code like IX at the end and cost more than $4 a plug haha

Anyways would it be safe to run the normal cheap (mineral) oil to try flush out any debris for a few Kms then drop it and pour in some full synthetic?

Or will this damage my engine more than clean it?

get a low weight mineral oil and a filter I like to use Valvoline Engine armour, only need to run it for about 5 minutes, ONCE YOU HAVE PRIMED THE TURBOS - don't start the car without doing this (as described, remove the coilpack harness) and crank for about 20 seconds let the starter cool for 15 - 20 seconds then crank for 20 seconds again (I cycled like this for about 3 minutes to ensure the turbos HAD oil) then drain and replace with synthetic . don't forget to bleed your cooling system once running, otherwise you will get issues with overheating due to air pockets. I just run copper plugs in mine and they are fine. if you are really an@l, or the oil is really bad after the 1st drain do the mineral flush twice.

Haha alright ill jsut get some 10-30 or whatever autobarn has on sale for cheap.

will let the old oil drain cold for an hour or so then add the new oil :)

and then prime the shiet outa the turbos :D

coolant is all good :) will do a heater on bleed once im running the car with the mineral oil :)

Thanks for the advice :D

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
