I've just recently gotten my old 89 crx si up and running. Haven't driven it since 2015 in highschool. I've gone through and replaced a few things like new dizzy, water pump, timing belt, plugs and wires, clutch, flywheel, rear main seal, dropped gas tank and replaced fuel pump. Now that I have it back to proper running shape I'm slowly getting more parts for it. Oversized 76mm P29 pistons, y8 head gasket, skunk 2 intake manifold, trying to get in touch with delta for a cam regrind, not sure if they're still doing them considering most posts I see are from 15 years ago lol. should make 11.9:1 or maybe a little higher compression, with a good cam hoping to get 135hp or so anything beyond that is great. Will I need to worry about getting a chipped ecu for this or can I stay on stock tune? Also should I worry about fuel pressure or will stock fuel system suffice? Also already has 2.5" or 3" apexi exhasut with header. Any current places to get a cam regrind and suggestions would be great as well.
