The one facing up is not a port. It's a pilot hole for a supplied bolt to anchor down the map sensor if you chose to run it in the back of the intake.

I didnt realize this before. So thats another issue. Easily remedied but still its another issue I overlooked.

Hopefully Ill have my intake back this weekend. Im going to tap the back of it and add a fitting for the hvac system. Anyone know what size the hvac lines are? Also Ill work on flattening the steam tubes to clear this intake. I dont think itll take much. It looks identical to a fast 92 underneath.

Just to update. Got my intake back today with the runners smoothed out. Im going to drill and tap the intake tomorrow to add a 1/4 nipple for the hvac system. Ill report back on that.

Someone will need to make a write up on how to install these on a 4th gen. Its not a bolt on part and will require some modification. Ill gladly help with what info I have so far. Hope to have it on and running by next weekend.

Would you post pics of your smoothed out runners? It was my first time porting my intake and just curious how yours came out. My heads/cam parts will deliver tomorrow so I won't be to far behind your install date.

Just add a T and just drill for the map sensor

use one T for the hvac and brake booster.

There's a port for the brake booster. May just T into that port.

So if you want to have the map sensor in the front, from the pics it looks like this does not have a sensor port in the same location as the actual ls2 intake (which is front pass. side), but in the cover for the EGR hole there's a port (?) that looks like it would have to be drilled out?

I will post pics as soon as I find time. I have a uncompleted rough draft of a write up but I am not done. I still am dealing with fitment issues.
