Yes.

Tomei were my start point but I couldn't find a reference to an 86mm piston, only oversize ones.

Didnt look at ACL or Nitto (Not that the NItto list has an 86mm size anyway) because I didnt want to use them.

Have CP pistons currently and given the issues I have dont want to go back there either.

Despite all available evidence being to the contrary I am not a complete idiot. I understand cps reputation. None the less I would still like to establish who makes forged pistons in 86mms because from what I can see it is a much smaller number than for oversized pistons for obvious reasons.

I'm not sure who's insinuating you're an idiot but it's certainly not me! I'd love to know what went wrong though. I've got 2 RB's with forged CP's so keen to know what could potentially go wrong.

Are the slugs going in a brand new engine? The reason I ask is most of our 12-21 year old RB's are pretty much due for re-sizing by the time their due for new pistons.

Sorry for deflecting from your goal!

My quick Google search brought up-

Arias

Wossner (??)

HKS

CP

JE

ACL

Gong Chang (holy crap, the Chinese are on board the forgie train!!)

Apexi

Pretty good choice really..

I would also line to know what went wrong with CP pistons.

I believe that information may be more valuable that the current display of attitude. Particularly to us CP users who have put their hard earned into big builds.

Attitude? FFS.

I said I had engine issues.

I said I didn't want to use CP's again.

I did not say the cause of the issues were the CP pistons or that there was anything wrong with the brand.

Happy?

    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
