The oil light can be an indication of a low oil pressure and that would explain
why the vtec only works occasionally. Are you having any speedometer issues?
If you are going to run the oem B20Z bottom end at least get some ARP
hardware for it (head studs and rod bolts) and don't rev it any higher than
8000rpm and put some fresh bearings etc in it.
Those are some nice parts you have there :bow: Car should be sick when
you're done. Is the Spoon Sports head gasket a single layer one? If yes
could I have the part number?
