FTO AUSTRALIA

Hi guys,

Going through amayama and it seems each bank has different part numbers.
What would this be for?
I found it pretty odd as I really expected all 6 pistons to be identical.

Additionally, I've seen most other engines have aftermarket oversized cast pistons for a rebuild but have never seen them for an FTO.
Anyone know where there are some, if at all?

Cut outs for valves maybe

I know that RPW lists the CP ones for oversized values of 0.5, 0.75 and 1.00mm; but they're 8.5:1 compression and are expensive because forged.

The valve cutouts seem the same but this would make sense as the intake and exhaust valves would be on different sides of the pistons depending on the bank they are in.

As for replacement pistons, I meant replacement OE pistons that are cast for near stock motors
