yea we got the new b20 in my g2 Da and the thing is poping backfiring from the intake and exhaust and making all sorts of noises soooo i figured the problem is the timing... i got AEM cam gears and i could have sworn they were lined up when i adjusted them with the new belt, but i guesss i was wrong if anyone has anytricks to lining up the cams please post... i got the hatch marks lined with eachother and the cam line/ and the top/up mark was pointing up(well what i thought was up) thnks again

 

loosen the tensioner and re-adjust
