Ok recently did a full bottom end build on my sr20det did the following to the bottom end : 8.5.1 cp piston .20 bore , brand new crank , eagle rods , acl main and rod bearings running a apexi 1. 5 hg
Issue of concern is that there's prolly only about 8000 miles on the block unsure about the head but im concerned about my compression number
Dry test wet test
#1 138 psi #1 145
#2 140 psi #2 145
#3 145 psi #3 150
# 4 145 psi #4 150
Are these normal numbers or did miss up some where or could these be something to do with my valve seals or valve seating
