okay guys I built a gsr with 12:5 CR.... after marker cams, cam gears, etc... when I try to crank the motor it seems as if the belt is going to skip a tooth... It rotates everything but it does not look tight at all it looks as if it is going to fall off and kind of moved weirdly... what do you guys think it could be... The belt is TIGHT BTW....

not tight enough..put the engine at tdc and take pic...of belt around camgears

It is tighter than my friends type r and ls vtec... idk what it is. and it is in time both cam gears face eachother at TDC... im thinking maybe the tensioner is bad?

Mr. EG

Did you properly rotate the engine and tension the belt according to a helms manual/ OEM spec? You may have slack on the opposite side of the belt.

You have the correct timing belt right? Don't want to sound like a dick or anything BUT I have seen someone assemble a GSR w/ an LS belt.

it is a GSR timing belt. Also, yes it was done to OEM spec.

It would take quite an amount of milling to throw off the timing. My head has been resurfaced at least 4 times and everything still lines up at TDC.

ya it would take quit a bit but just asking anyways.... i think its just the tensioner
