    I'm just finishing up my t67 turbo build on my l67 with an l26 mani and need some help with the vacuum routing. I'm running stock l67 TB, MAP, and fuel rails. Anyone have any diagrams?

    i used a vacuum block made it easy. you can block off the l26 evap port and use the l26 map hold plastic piece, tap it and put a brass nipple on there it works nicely.

    Thanks. I should've mentioned that i do have the EGR blocked off and already have a brass nipple where the MAP went. Link seems to not work for me for some reason. :/

    It didn't work for me either, but I tried several times and it eventually worked.
