i received my ported IM from Mace today, so i started the tear down. Here is a partial step by step, i will update as i go, i am going to paint the ported IM and also port the intake ports on the heads so it will take a bit between updates, but let's get this party started.

i took a lot of before pics, i won't bore you with those, we have all seen our engine bays!!

i started by removing the engine cover and then my SLP intake tube.

then unplug the harness from the TB, and remove the 4 bolts with a 10mm wrench of your choosing. i used 1/4 drive ratchet and socket.

set TB aside, then i popped off the little clips that hold the rear part of the cover on, then fished it out of the engine bay, a little tricky!!

then disconnect all the hoses (3) and clip (1) holding stuff to the IM.

there is a bracket at the front of the engine that needs to be removed, (2) bolts, 10mm wrench. there is also a bolt holding a harness bracket on the pass side of the IM, also a 10mm wrench required.

next i removed the 8 bolts holding the plenum cover on, 10mm wrench.

then the 4 bolts that go through the cover to the heads, 13mm wrench.

then you can remove the cover after removing the bolts, the rear bolt wouldn't come all the way out, so leave it in while you wiggle the cover out. this gives you a bit better access to the rear bolts that are horizontally installed. this is where a 13mm ratcheting box wrench with a swivel head works well, but mine hasn't arrived yet!!! i used an open end wrench to break them loose, then a crows foot by hand to take them the rest of the way out, worked ok, but the swivel wrench will be much appreciated!!

remove the 2 remaining bolts that have a 13mm head, at this point the IM should come right off, just make sure you have all the hoses and stuff disconnected.

there was a bit of oil in the intake, i guess i'll be adding a catch can soon as well.

here is a pic of the gasket sitting on the head ports, i will be fixing this myself, stay tuned for that.
