part number needed: 4age bluetop pistons

[cj]

I'm rebuilding my bluetop 4age engine and it needs to be bored to 81.5mm (stock size 81.0 mm). This means i'm on the market for new bluetop pistons. I'm specifically looking for european or japaneese bluetop pistons since their compression ratio is higher than the us version.

So, please, if anyone could help with a euro or j-spec part number of bluetop pistons...

Thanks a lot!

still looking...

I'm suprised to see that prices of rings and pistons are the same.
I'll post local prices also for comparison.

By the way, what do you mean by "105.75 € set"? Is this for 4 pistons or less?

Thanks again

Does anyone know the specs of those pistons?

I was thinking about ordering a custom set from Arias - 81.5mm, 11.5 compression. I know they have the redtop pistons, but i don't have the redtop internals.

This is what Arias are looking for before accepting an order:
• Engine make, model & year
• Bore size
• Stroke
• Rod length (c to c) and material
• Block height
• Compression ratio
• Gasket thickness & diameter
• Wrist pin diameter
• Pin offset and direction
• Application info
• Induction & fuel
• Camshaft specs
(gross lift, lift @ TDC)
• Cylinder head brand
model & part #
• Valve angle
• Combustion chamber CC’s
• Valve diameters & freedrop (valve edge to cyl. head deck)
• and quantities of pistons and hardware.
