yep, i had a jdm h22a and i have 210 across the board.

by the way i did this compression test with full gas pedal to the floor(WOT) with fuel pump fuse taken out and coil wire removed.

Re: (bluedlude)

that's decent,
A jdm h22 has higher compression thus the higher numbers

Re: (khalal538)

the compression of the motor has alot to do with the actual numbers that comes out. Most usdm motors i have seen are around 195-200.

7 PSI should be safe for that compression with stock pistons/rods

Add a few drops of oil in each cylinder and try the test again.
