ok getting it all balanced as we speak, just a concern, im leaning toward replacing the clutch but im getting it balanced my excedy, will the new clutch affect the balance that much?

  • 2 weeks later...

Ok just got the call from my machinist. $866 for the balancing, grub screwing the crank, checking bearing clearances, installing crank collar. So my build so far is very close to $5k

i doubt that anyone is still actually going to help me but i have some questions.

my stagea manual is in Japanese, but i have an r33 manual in English (only covers rb26 bottom end) will the rb26 bottm end and rb25 top end torque settings be ok for my rb25 neo?

what is my ring gap supposed to be, i just want to make sure it has all been machined correctly before i assemble it. (cp pistons, 86.5mm)

arp head studs, what kind of socket is it and what size?

assembly lube, is it normally in the oil section at auto stores?

Ok incase anyone cares. I'm going top 17 mid 19 oil 16.

The manual says to stretch the head studs, do arp studs need this done too? Will i need to re tension the head studs after the run in?

Head settings In my manual says

Tighten to 29N-m

Tighten to 98N-m

Loosen to 0N-m

Tighten to 25-34N-m

Tighten to 93-103N-m

But the arp booklet says 80N-m

What should I do?

just noticed something strange, in the paperwork for the pistons it says the rings are made to suit a specific bore size but when measured they came back at top .010 and mid .015

what grade file should i use to file the gap?

Just thought I would try the cp ring gap calculator formula and according to that my ring gaps should be top .018 mid .024 and oil minimum .015.

That's kind of disturbing.

ok update. out of the box the rings measure as follows, #1 - .010 and .020, #2 - .012 and .022, #3 - .011 and .020, #4 - .011 and .020, #5 - .010 and .022, #6 - .011 and .020. ive set all the mid rings to .022 as per cp specs. with any luck i can find a harder file tomorrow and set all my top rings to .018

and yes i realize im probable talking to myself, but im considering this as my blog from now on. that way atleast i can come back and find out what ive done/done wrong

    • Kinkstah, no, coilovers aren't illegal, especially as a bolt straight in. The illegal part will be if they're altering suspension geometry beyond factory limits, or the ride height is not legal.   Sounds like the blue slipper just didn't want to deal with any later possibility of mods appearing on the car.
    • The problem has always been that coilovers are able to be adjusted, almost at any time, to be too low. Most people who ever get/got defected for/with coilovers were actually afoul of the minimum ride height rule. So the interpretation by cops/inspectors was always that it is pointless to allow numpty to raise his coilovers and get the car inspected/cleared, then just drop them back down again as soon as they get around the corner from the inspection station.  This led to the interpretation that they were illegal unless rendered such that they can't be adjusted (ie, collars welded to the body, that sort of thing). That may or may not have ever actually been the official line, but I'm pretty sure it's not considered to be a solution these days. Coilovers themselves fall under clause 3.2 b of that manual, because they are an "installation of a variable ride height system" and they don't fit the exclusions in that clause (which point to air springs and other pneumatic adjusters). So, as per previous statements, they require engineering cert to be legal on the road. Once you have such cert, provided you do not adjust them outside the height range covered by the cert, you are OK. Without, you have an unroadworthy vehicle.
    • Here E10 is the cheapest fuel. And general advice is to not use it unless you hate your car. From what I remember it clogs up stuff in the fuel system or injectors?  With US/Canada being E10 across the board, does that mean that all fuel there is terrible?
    • Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW ) Edit: I checked. They aren't. https://www.nsw.gov.au/sites/default/files/2021-02/RMS-infosheet-light-vehicle-modifications-manual-suspension-and-ride-height.pdf
