2.0 LSJ Engine: "How to" Install COMP/ZZP S1 Cams, Supertech 75# Valve Springs, & GMR Cylinder Head
#104
Logged boost pressure the other day for the first time with the GMR head....
With the GMR ported head, I'm seeing a max of 14.3 psi.
Before the GMR head, I was seeing 15.1 psi with cams.
Before cams, I was making 15.8-16.2 psi.
All boost readings were recorded during an ambient temp of mid 40's.
This shows the GMR head removes a good amount of restriction.

Exhaust side help
Using this how to, I successfully took apart stock Camshafts, and reinstalled the new valve springs on the intake side. On the exhaust side though, everytime I take one turn to compress the stock valve springs air starts pumping from compressor through motor?
