Just compression tested and Leakdown tested my B18C5 Swap.
I will be boosting this engine on 5 PSI.
Are These safe numbers?

Compression:
1 = 210 2 = 215 3 = 215 4 =215

Leakdown:
1 =15% 2 = 5% 3 = 5% 4 = 15%

Just want to be sure these #'s Look Good
Thanks,JIM

Those numbers are very good for that motor. It is in great condition. The way you can tell i s by the compression numbers, they are no more than 5 points away from each other ( i think you allowed no more than 10% difference but im not sure ) and thats more than acceptable. You have a great motor! :D
