    The left side of the manifold.Where the zip ties are.Pop out the ties and tap there.

    A how to in jerry's build thread on tapping the bosses, post #1...http://www.greenhulk.net/forums/showthread.php?t=87711

    If you have any intention of installing a riva Inter-cooler in the future. don't tap the right boss as it has to be cut off to install the IC.

    Here is another idea i've seen on here..

    I have the rear boss tapped for the BOV, IAT sensor on the front next to the OEM temp sensor & use the R&D adaptor(only fits pre 2011 skis) for my boost gauge. It's also not a bad idea to cut the front boss while you have it apart if you plan to upgrade the IC at some point. It's necessary with the Riva cooler, but even if you use something else it couldn't hurt to give yourself a little extra wiggle room.

    I tapped my front boss,then installed the Type 14, and luckily the thickness of the manifold will allow enough thread engagement to cut off the boss.

    Thanks guys that was helpful. I'm putting the fizzle IC in, dont recall seeing anything about needing to remove the boss, what do you do just grind it off?

    Hopefully people that have the fizzle IC installed will respond as to the clearance before you cut the boss off. If you have the clearance, that location is perfect for the BOV line.

    I used a cordless dremel with cut-off wheel while manifold was still on ski. A lot more options with manifold out. Even a simple hacksaw will work. I cut mine off where it starts to bellow out and hit it with a file quick. Mine doesn't look as pretty as mjh3ides. That's some serious OCD pale rider filing there.

    Was actually only about a 10 min job. I used a hacksaw to cut it as close to flush as possible, then used a dremel grinding stone to round off the edges.

    Thank KamikazeGPR, that's good advice. I will check the clearance for the IC first before cutting it off. If I don't need to cut it off I will do as you suggested and tap that side for my BOV.
