Right now, pushing a F23A SOHC VTEC Engine. Its runs decent, but looking to upgrade. I found a F20B DOHC VTEC Engine (under a grand)that will fit and I believe will even hook up to my current tranny, so really thinking about getting it. Also wondering what else I would have to change? ? ? engine harness? ? ? ECU? ? ? Motor mounts? ? ? to transition from SOHC to DOHC. . . Any suggestions will be great to help me out. . .
