hi all, i have been doing a rebuild for like a year now and i plan on breaking my car in with new pistons and rods on the stock components. However i have a standalone ems that i will be adding later, so im trying to get things ready for that at the same time. my problem is i need to pass smog before running the ems, my main concern is that if i drill out the j-tube for fuel return will it have problems or maybe throw a code that wont let me pass smog. My second problem is placing the halltech sensor for timing, i would greatly appreciate a picture of a stock belt setup so i can see where to place the sensor without rubbing the belts. thanks in advance for any help.
