Hi everyone. I own a Civic Si 9th gen. I'm joining this forum for help. I'm buying either a K20A2 engine or a K24 engine of some sort to build this year. Hoping to pump out at least 325hp and 250ft of torque. I'm planning on boring it out, increasing compression a bit though I live in California so not sure how high I can go while still running 91 Octane. Anyways thats just a bit for now, hopefully you'll all be in for a surprise for my project I plan on building but, I'll tell you guys once I actually start on it.
