TODA Pistons

I want to change the pistons. I found some TODA's pistons.

I want to buy the 82mm and 20pin. Is the compression ratio like a standard 11,3:1 with oem headgasket? If i want low it?
What is the meaning "over sized"?

Oversized means that the bore size is larger than stock. Lowering the compression is by usingh a thicker headgasket.

So the TODA's pistons have standard compression. And i can adjust the compression with a headgasket?
But the wiseco pistons have compression ratio for 10,3:1 to 11,8:1.

No the toda pistons have 11:1 and higher compression ratio's.
But the whole point of these pistons is the higher compression.
You could lower it a bit by installing a thicker headgasket, but then why not just buy a thinner headgasket for your current engine and accomplish the same thing?

i have problem with some rods in the bottom end. And i rebuilt a 4agze bottom end with high compression pistons

The reason to use such nice pistons is added protection against detonation and for lighter weight. Plus when running higher lift cams it will reduce your dynamic compression.

so is it good to reduce the dynamic compression?

I'm quite newb in those things but the dynamic compression isn't it reduce buy hi-duration cams hier than hi-lift cams...?

yes you're right boomex
it's the duration and not the lift
