top swap L36
I just finished my topswap. I have:
FWI
ported L67 TB
Ported m90, LIM
Ported heads with SI valves, L76 springs
light weight retainers and push rods
Speed daddy headers
2.5" full exhaust with no cat and magnaflow muffler.
Tuned by me.
and I still had KR with the 3.8 pulley.
all dialed in I can safely run 12.5-13 degree of timing at wot and see about 7.5 psi at around 6k rpm.
