I have a fully build LS engine
Which Timing belt to use?

I thought that if i change the water/oil pump to GSR I would use the GSR belts.. But that is not the case (Too long).

Any sugguest on LS timing belts?
Must handle atlease 8-9K RPM.

 

the gsr belt should work. are you sure you have the right belt and routing it correctly?

 

if you want to rev to 8k+ you should use the GSR waterpump thus need a gsr belt too since it is just a tid longer.

 

I'll take some pix later

Belt is a GSR belt
