Hi, I have been searching for the past week and I still cant find the answer am looking for. About three months ago I bought a used engine to swap into my ride, it was a 98 d16y8. At the time that I installed the engine I also installed a Intake,header,exhaust,hi-flo cat,fuel rail, underdrive pulley kit, msd,and a cam gear. Car worked great for about a month and then I started to get detonation, and two days after it started when I was on the freeway it popped and turned off, I tried to turn it back on but it would'nt turn back on. When I got it home I checked the engine and it looked good but when I checked the spark plugs they were all orangey color and on one of them it looked like the piston was hiiting on it because the little metal peace where you gap them was bent. So my question is sense I'm going to add a jackson racing s/c and a 50shot of nos(maybe) should I build my motor like alot of the guys that go turbo or should I get a new engine and transfer all my mods and add the s/c and leave the engine alone because their is no need to build the engine with my set up? Sorry for the long post and thanks in advance for your help.
