Doing a B16A into a 1990 Civic Si. The B16 is a OBD 0 sir 1. It has had the following changes: Block has been bored .010" CP pistons (10.5-1 comp) Eagle rods Head and block have been decked, comp should be around 11.0-1 Mild port job on head, 5 angle valve grind Brian crower stage 2 cams, valve springs and retainers. Adjustable cam gears Cold air intake 2.5" mandrel bent exhaust with Magnaflow. Thanks for hanging in there so far, here is my question; What tuning will I need to do with this set up? I have a Walbro 255 pump, will just increasing fuel pressure be enough? Do I need a standalone EFI system (hondata) or a VAFC? I have a wideband a/f sensor so i'll be able to see if its running lean. I haven't run the car yet, I wanted some help with the tuning before I start it up. Its a mild setup, I hope I can get away with just a fuel pressure increase but ANY help would be appreciated. Thank you for looking.
