Hey guys

Currently got my neo motor stripped down and have slightly cooked 2 pistons and seized a comp ring. Its in a r32 and it was a good set up for track and drift work. Im want to rebuild it because then i know the motor is fresh and i can get good new parts cheap and machining through a mate.

The trouble is we can't find pistons for r34 rb25det neo motor only rb25det pistons apparently they dont make them for the neo motor. I'm oversizing the block 0.5mm and want to fit acl pistons 86.5mm. the only difference i can see in the pistons is the standard ones have valve cut out in the piston head. the acl don't have valve cut outs but the raised dome section is more sentral so it looks like the valves will sit on the edge of the dome.

Not many ppl know much about the neo motor and can't help me out. has anyone seen or tried this, just want to know if it will work

Cheers

Dan

No.

As far as i am aware the combustion chamber in the head of the neo is smaller cc's than S1&2 25's.

Talk to an engine builder for options. For this particular info I would reccomend Lewis Engines.

They have pretty good knowledge when it comes to NEO's

    • Yeah I also looked at Plazmaman, but, it ended up alot  cheaper getting black ones through EFI when you also added in the delivery cost
    • Nice shot! They look super clean. The roof rack delete on the black one is interesting. Would like to see more pictures from different angles. It's subtle but could make quite a difference to how the car looks in profile.
