Cheapest about are 73.5mm Hypatecs, from Minisport in SA.
Russell Engineering has their own 73.5mm ones, similar to Hypatec but a better dish shape for power.
These are both very good pistons. :wink:
Both suppliers also have 73.0mm ones, if you want to keep the 73.5 bore size for next time. 73.0mm gives 1360cc.

Karcraft sells Powermax 73.5 and Hypatec 73.0mm.

I've heard of Mazda pistons being used.
I'm not sure about Nissans but at $170 or so A SET with rings, I doubt you will beat the 73.0mm Hypatecs. :wink:

<edit> the link says 1330cc but it's a typo. +.094" is 73.0mm, = 1360cc.

Yep 20 thou over mazda 808 (or similar) are 73.5. Mine have a dish machined in. Don't know about any pin work sorry as these were done by previous owner. Agree with above - if I was replacing I'd buy mini pistons.

We could always send some kiwis back with a set each in their luggage and you could meet them at the airport. :D
