back in february i started doing my ga to sr20 swap on the car. two weeks later after doing the swap i realized i had a spun bearing on the 3rd piston. i just got everything back from my machine shop. king balancing in phx. i got new pistons at .20 over, new rods, new main and rod bearings, micropolished and balanced crank, and the head deck shaved off a bit. i also just finished putting it all together and will hopefully put it in and start it up this weekend. will the car was up on jacks i also did the nx2000 front and rear disk brake upgrade. :hal: my question is to anyone thats done this. how many miles do i need to drive to let to motor break in untill i start to give it hell?
