Tuning Advice, B18B1 (OBD-0 w/ PR4), built head
Alright, Here's my statistics:
Motor is in a 1989 Honda CRX Si
B18B1 swapped down to OBD-0 with a PR4 ECU
the PR4 ECU is already Zif-socketed
---------
Head is from a 92-93 B18A
Port & Polished Aggressively
Crower Titanium Retainers
Crower Dual Valve Springs
Ferrea Stainless Oversize valves
Delta 272 reground cams
OBX Cam Gears
Cometic MLS Head Gasket
Stock Lower Block
I have plans for running a T3/T4 on this setup down the road, but will be running all motor for the time being.
Now, how do I compensate for the 272 duration camshafts? Should I alter the ignition timing or the cam timing at all? Also, where should I raise the amount of fuel being injected? Mid/High-Range i'm guessing?
Thanks,
Richard
