Hello everyone, Here is the scoop on whats happening. After purchasing a new timing kit and oil pump with front cover for my redtop sr20det, I pulled the motor an broke it down an installed everything. Now I get it all back together and ready to go and when i try to start it fires against itself meaning it feels like the timing is off 180 degree. Now when i look at everything, meaning the cams, chain, an cas, everything is lining up and looking right. When 1st piston is at TDC, 2nd mark from left on crank pulley, the cam sprocket marks are lining up with the chain marks(silvers) and the lobes are pointing outward, away from each other, and when looking at the cas, its showing the marks are lined up, far left mark with the casing cas mark. Now i really have no idea what else it could be considering when i rotate the crank, the cas lines up almost perfectly every 2 turns which it should (i think). Maybe there is something i am missing, i do not know, ive searched everywhere and all the 180 degree out of timing info points to having the cam lobes pointing towards each other when the cas marks line up. Please help anyone, I can take pics of how it sits if anyone has any ideas......sigh (maybe the cas is bad???)
