I recently purchased a used PR3 head thats been worked by JG Engine Dynamics. My plan is to fully build a motor starting with the head because I already have it. After receiving it from the first owner I sent it to JG for an inspection to confirm what I bought. It was suppsed to be the Pro Series Gen2(top) but its something lower like the Pro series(med) or Redline(low). The thing is do I want to go N/A or turbo. Since Im at high altitudes they said I should go turbo since Im gonna be fully built and upgrading to the Pro Series Gen2 would run me $300. Im debating which way to go. I wanted to throw this motor in my ITR but I might go a different route like a HB but who knows. What you guys think I should do?
