1992 G16B EFI Motor

If the pistons only have an arrow and B1 or B2 on the top are they standard size?

IE The engine has NOT been re-bored at all?

Oversize pistons nearly always have .030 or similar stamped into the crown.

G16A & B Standard bore is 75.0mm

Thanks Wants - that is how I have always seen it but with Suzuki might have been different - What made me ask is the motor or should I say car has 235,000 k's on it and there is no sigh of a ridge at the top of the bores at all. I can not even feel a thing when I run my nail up it. Just thought it must have been re-bored but is the pistons are standard it must have had a very soft life.

That would explain no wear on the bores
