It’s a modern piston with 4 valves and based on the dome not out of a turbo so I’d guess QPV, 4200 or GT

Cylinder bore is 94mm, it means these pistons are from some 4,7 Maserati. I need them for my racing engine Ferrari 430. I can not order them from Maserati because I don´t know the exact item number and dealer Maserati doesn´t know it...
Absolutly the same pistons I have seen with three rings. Help me with this order number,please.

Yes, I know these diagrams, but there is maybe 4 or 5 options. Also I have found some pistons from Maserati GT 4,7 on ebay but I didn´t
find this shape as pictured.

I hope you find them. It’s fairly unlikely that anyone here will have rebuilt an engine, much less replaced the pistons and then needed the ones you are looking for, but hope springs eternal!

Thanks for photos, your diametr is 92mm if this engine is 4,2. I need dia. 94mm. Also your piston is for lower compression ratio.
I need the compress. ratio arround 12 - 13.
Thank you.

I’d be surprised if there’s a Maserati that runs a compression ratio of 13:1.

Also the piston in your photo only has two rings which isn’t common in a road car.

Are you positive it’s from a Maserati?
