ok so i still havent figured out but.....yesterday i saw my bro driving down the highway so i caught up to him and he (tried) to take off ,he has just a d16a6 in a hatch and i shifted down to third and got on it for about 5 seconds and i couldnt believe but he pulled on me and i have a b16 so whatever the problem is made my car slower ALOT SLOWER!!!!, also today i noticed it the high rpms at fuill throttle it sounds like its detonating and its throwing alot of black smoke out of the exhaust ? could this because i jumped a tooth on timing and now my ignition timing is really advanced? i dunoo but im about to just got a new long block
