You want a Cheep Cheep Solution??? why you wanna be cheep when you say you got a "heavily built" motor. Don't be cheep, be smart about it

run a chipped Ecu that can be tuned, set your RPM up to allow you to top out at 4000, so you wont go over it and you don't have to worry about blowing your motor. Change the oil 2 or 3 times with in this break in period also. Come back after the break in, and get it seriously tuned and dyno'd.

the stuff you listed isn't technically a "Heavily built motor"

You should LS/VTEC if you want power
