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?)

    • Bump on this to not make another post, had a ‘head drain’ leak on me and have the engine out as we speak. Planning on just putting a new freeze plug back in , plug the tapped holes and just be done with that headache.    Now I still want to relieve pressure to allow oil to pass down the blocks returns easier. I’ve seen catch cans with multiple vents help folks with this issue on this forum.  I’m wanting to make my own. I have some pictures here of my setup if anyone can help how I should plumb and design the catch can I would deeply appreciate it !   rb25 Oil upgrades: 1.0mm restrictor n1 pump/billet gears extended crank collar  extended sump with trap doors/w welded fitting    
    • The Frenchy's kit is the way to go forward. A modern compressor that weighs about 1/2 as much, is at least twice as efficient, and will do a good job on R134a. And of course the kit has everything else you need to connect it up and have it work properly.
    • Hey all , I am in the process of having the AC system in my r32 GTST converted from r12 to r134a and I’m being told my compressor has gone bad and I will need a new one. I was wondering if anybody has any suggestions for what is the best route to go aside from dropping $1500 on a new oem one? I did see that Frenchy’s performance garage offers a kit to mount a Toyota compressor, has anybody actually used this kit on their car? Or is there anywhere I could purchase just a clutch? Any help is appreciated.
    • Well, your RB20 ECU loom won't have wires for the boost solenoid, that boost sensor, and possibly one or two other things. There could be differences in seemingly random things like the charcoal canister purge solenoid, because the 25DET has to handle boost in the vacuum system and the 20DE does not. I don't know - I haven't looked. It is very likely that all the most important things are same-same, being the main sensors like AFM, CAS, etc, and the injectors and ignition. Not that you'll need the AFM for the Haltech anyway. I would suggest that you would seriously want to sit down with the pinouts for both ECUs and just go through them and highlight green what is the same, orange what is different/missing, and make a plan from there. It's not going to be difficult. It will either be the same or need to be fixed.
    • yeaaa that's why I haven't done any wiring to the stock ecu harness because I have the haltech, but then that leads me to the other question of "is the pnp harness really plug and play?" or would I have to still switch some pins/wires over because the pnp is for the rb25det neo harness, and not for the rb20de neo harness. was really hoping to find something to spoon feed me since so many people have done rb20neo + t conversions, but man this is rough.
