ok guys i need a lil help im pulling my pistons and rods out to re hone the cylinders long story... theyre mahle forged pistons and crower rods its been honed last time. technically not even 100 miles ago anyways this will be the second hone do yall recomend standard bore rings or over size? what size to be exact im looking at some mahle 3.908 non file fit standard tension. do yall recomend anything different my other rings were file fit theyre were mahle to but came with the pistons

 

No matter what they are, you should still check the gap.

If your at 20psi like ur sig says, then the stock size might be ok as with 20psi, ur gonna need a lil end gap so they can expand.

 

so what bore size would you recomend? it was just honed at the machine shop they said they took 1/2 thousandths out
