i had a turbosmart mbc now i got a forge mbc witch side is for the waste gate and witch is for the intake manifold.
sorry for the noob question

 

The general rule is the side opposing the spring is the source line and the port on the side of the cylinder is the WGA line. This isn't always the case with all MBC's. But with the Forge and Hallman it is. The port opposite the adjuster knob is your boost source side. WGA is on the side running perpendicular.

 

thanks
