Hello, I have bought two set of ring , but those are have the ring gap problem, a little bit larger than OEM spec.
Ring gap:
top ring : 0.19- 0.20
2nd ring: 0.20-0.21

I know somebody run with little bit loose for their engine, My car just for track, May I run with this ring gap?? If not, May I buy a set of oversize ring and file it?

Thanks

If you are going to track this vehicle... run those gaps. You should be just fine.

If run with this gap , will it make lot of crank pressure or compression leakage?
my set up with high compression piston and run with N/A

Not likely... maybe a slight increase in oil consumption... but you reduce the chances of the ring gap closing up to zero and damaging the engine from getting the parts too hot.

Thanks.
You know me i am say in inches , not mm??
0.19 inches and 0.21 inches

Thanks for your help, i do not have any experience about ring gap clearance.

Sorry OP, I thought you meant .019" for the top ring and .021" for the second ring. If you meant that you have measured .19mm and .21mm, these values are NOT loose at all !!! That would be very tight and require filing.

Brembomaster

YESYES,, It's is 0.019' for the top and 0.021' for second. ( convert to mm is 0.48mm for top and 0.51mm for second ring)

What you have is fine.
