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

    • Ah ok. I seem to be mixing it like everyone else does so not sure what's happening. Will experiment with it more.
    • Depends on what you mean by OK. First up, was this done cold or hot? Are they reasonably consistent? Yes, they are reasonably consistent. Could be better. But unless it has had a build at some point, it is a ~30 year old engine and you'd expect some variation. Some of the difference could also be in user technique Is it good compression? Well....not numerically, no. New they were >160 psi. The one at 140 would be fine, in that context. If they were all ~140, you'd be reasonably happy. But the one that is @120 is twice as far down from the original numbers as the one @ 140. But.. (again)... technique can play a part in the absolute magnitude of these numbers, and the quality/state of repair/accuracy of the pressure gauge is not known. In the context of the above, the compression tester that was used last on my car is regularly compared to a known good pressure gauge. Not calibrated, exactly, but compared to a reference instrument that is not used for any other purpose, so cops no abuse. So we can trust the measurements off that tester. But another tester in the same workshop wasn't being compared against the standard and was reading a good 30ish psi lower. When you're reading 100 psu but the engine is really doing 130, you can make bad decisions.
    • More likely from tiny bubbles in the filler/putty. Maybe be less aggressive when mixing it. Perhaps invest in a vacuum chamber to pull the air bubbles out?** **I don't know if this is a thing for body filler. I see hardcore epoxy makers degassing their mixed resin on the regular.
    • IIRC, the speedo on these is fed from the sensor in/on the snout of the diff.
    • They were. I bought the AWD for experimenting but racing it would disqualify or disadvantage me from a few race classes. Def getting a FWD for racing.
