Wat up guys, need a little help here!!!! I have an ls/vtec motor that i just cant get the timing correctly....it's a b18b block and a gsr head...im using a gsr water pump and t-belt, type r oil pump, and adjustible cam gears set at 0 degrees... the motor is at TDC and all the markings on the crank and cams r on point....when i start the engine it seems to be retarded and dont know why...i have to advance the distributor about 10degrees in oder for the engine to run good. does anybody know why this is happening... i did some research but dindt find much... the only thing i found out is that vtec engines have slightly different timing than non-vtecs, and i read this in a magazine, dont know if is tru or not... does anyone know how or why this is happening??? and if so should i advance/retard the cam timing or anything??? Please guys any input will be appreciated!!!!! Thank u !!!!!
