I've read that its optional to have this installed but as far as this being my first cr-vtec build, I want it done right. I've seen where they have tapped 2 holes on the front side of the valve cover and also heard that it can be tapped from the back of the b20 block. MY engine is on a stand so it will be easier for me to do this but I need a lil help from the H-T family. My current setup is a B20b block with a GSR head and a blox manifold. I want to tap it from the back but not sure where. I'll post pics later of my setup. Thanks H-T for the help!

 

there are (2) 14mm Allen Plugs on the back of the block, take those out, then buy the ones off of a prelude? that have nipples for hose on them, or get the ones from B&R fittings that have -10an fittings built into them.

 

Can anyone tell me what model Prelude has these plugs.

 

I believe the ones from an LS will work too.
