I have a set of CP Pistons for an RB25 Neo. These things aren't stocked by anyone and you have to order to be made from CP which take about 4 weeks.

They are exact copies of factory pistons but they are 86.5mm.

Other alternatives to CPs I have found were JUN ~$1900 and Arias ~$1700

Location: Brisbane, can post.

Price: $1350

Contact: Through PM or 0431119536.

Cheers, Alex.

How would they go with a 3L bottom end and a NEO head?

I've heard the compression is very different between an rb25/30 non neo and an rb25/30 neo.

Only ask cos if/when i ever re-build it'll be onto a 3L bottom end for sure...

i have not taken my engine out yet so not sure, if its fine i will go with 86mm, if its a bit worn out i want to go to 87mm im trying to skip the 86.5mm area plus im wanting to get cp to make me custom ones and i need a part number for them to start me off. i dont want to take my engine apart just to send them a NEO piston

all they have on their website are either rb25 or rb26 pistons, no NEO ones

who is quantum???

Edit... just saw the pic and noticed these are a way different looking design to the SC7307... these are custom then? (NOT SC7307?)

      Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?

      My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.

      There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.

      I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.

      Yeah - I mean, go the other way. Smaller range. Not larger.
