The latter of the two is from a 6.5psi d16y8 motor. Sidemount DSM intercooler, DSM bypass valve, 2.25" catback, 2.25" downpipe, STOCK fuel and motor, not even an upgraded fuel pump.

The first being my f'ed up motor. Possible blown headgasket (dunno when it happend) bad rings, 450cc injectors, 255pump, 8psi, etc...

compression was 160 160 150 155, after a cap of oil: 210 210 200 205 (I believe) which suggest the rings are bad.
The day after, I had a compression test.
