are g16b engine able to have a 3mm bore increase or will that sacrifice its overall integrity too much?
Im just interested as in the old days suzisport advertised 1750cc piston kits which now dissapeared.

3mm oversize will give 1720cc

[alien]

perhaps they were using dished pistons also? (EFI g16 has dished and i believe carby doesn't?)

Piston crown dimensions will not alter the swept volume.

3mm over is a fair wack! I have no idea how thick the liners in them are.

[pezz]

shorter rods?

[JrZook]

Rod length also will not make any difference in the capacity as the stroke is determined by the crank throw and the rod just relays that.

Yep. A common misconception. I think it's because so many "stroker kits" come with new rods and humans have a tendency to make up their own links between causation and correlation: "Increased engine capacity needed new rods, therefore new rods increase engine capacity.", or something like that.

At 3mm there would be no gasket left between the cylinders when my motor bloke looked in to it

Only some of them:P

What is the biggest oversize piston you can buy from a reputable piston manufacturer? That's how big i would be goin...

I went 30 thou

78mm mazda pistons and a custom head gasket from ACL . The little end of the rod needs to be reamed out to 20mm ..

can you share more about the pistons or results? I know the head gasket is 77mm so did you make a new one and impression or opinons on this setup?

Heya D Man, thought I was repeating myself or hearing my own echo! few G16 fans in this little world maybe more here than there
