Think outside "The Box"
I am researching to find the best motor swap. I am trying to stick with 4 bangers only. I want to get the best motor for the turbo setup. I dont think I'll be revving past 6k rpm. It would be nice to go to 8K, but really not needed. I need a good hp and torque range. I can start with non turbo blocks and work in my own turbo systems and EFI control, not a problem. What would be a good motor to get atleast 250-300 hp/trq from and still be reliable? It will be connected to a 5 speed.
