It started a few days ago. Noticed a ticking from the top of engine. Definitely sounds like a lifter. Have not been able to pinpoint which one. Figured I need to replace the lifters or at the very least remove them and pump them up. Then while driving, it felt like there was something restricting it under acceleration and sometimes would come out of it and pull just fine. Now, (every time) under full hard boost it pops, cracks, and backfires. A At part throttle it seem to be fine. It idles and starts up just fine as well. ANY IDEAS where I should start? Car is a 92 s13 with a redtop sr. t28 @ 10psi, starion fmic, 3" turbo back.
