okay i have a built b20vtec with a vtec water pump. I am supposed to have a gsr timing belt right? im not sure if it is since i bought it from someone but if i was using the ls timing belt wouldnt it be more than just a half tooth off. my b20vtec is built with 12.5:1 pistons and skunk cams. could running the intake cam 5 deg. retarted hit the pistons i need help

 

i have a b20vtec.....used a ls water pump type r oil pump with an ls timing belt.....fits nice and snug no issues....when i had a vtec water pump with a gsr belt i was off about a half a tooth so maybe you are having the same problem i used to have....
