I just bought a 03 Sentra spec v and am planning to dirt track it. I am new to the Sentra world and am wondering what would be the best way/parts to use for a build. I have to stay within 20% of the factory psi compression in each cylinder and pull 18 pounds of vacuum needs to be stock appearing. I just want it to be reliable because it’s going to be running high rpm the whole time and I am wanting to tune and possibly raise the rev limiter or just get a chip. The motor in the car apparently jumped time and I have another motor and tranny that supposedly run so I’m going to rebuild the one in the car
