Oh yeah, another fun tidbit. Stock SOHC or DOHC internals are good to about 200ft/lbs of torque. MAX. Good luck trying to get “more than 100hp” like you said in your original post. The shitty powdered rods will just fall apart. 200-225whp is about all you can safely make and you may not even get there with a SOHC. No one turbos a SOHC, it’s not worth it.
