I wouldn't worry about it if I was going to keep it stock but I was thinking I would lower the compression, change the fuel system, run e85 and turbo it. I have my old Subaru to daily if I have issues but I would like it to be semi reliable after all of that.
an unopened b30 can take up to roughly 600whp on corn juice. if you still wanna open the motor up, might as well upgrade rods and pistons and shoot for 800+whp
