For the drain tube, drill the front of the oil pan just to the right of the crank pulley. Be sure it's angled correctly (straight forward) so the hose doesn't interfere.
Anything bigger than a 3/8 line is ok.
NAPA has the taps and drill bits you need, once you decide how big of a hole you want. Home Depot has some assortment of brass fittings as well.
Go ahead and wrap your downpipe now, it's easier. Do the manifold too, or get you some booties for the plug wires.
Make sure you have all your gaskets before you get started, or a tube of rtv (orange).
Gap plugs to .030
On initial startup, make sure the oil is coming out of the drain tube.


Tip>>Loosely assemble the hotside before tightening anything. Same goes for the intercooler side.

VERY IMPORTANT!!!!!!!!!!!!!!!
----------------------------

The driver's side o2 goes in the same location it's in now.
The passenger side o2 goes in the downpipe. Choose a location that is at the same level as the driver's side and that will be good enough.
Don't do this and you're truck will run like sh!t.
-----------------------------
I highly suggest SD tuning for this setup. SO keep that in mind when routing the intercooler pipes and whether or not you're going to keep the maf.
If no maf = get a 2002 fbody intake air temp sensor and connector. Cut the tan and black wires on the maf (the two end ones) and take them to the new iat.
I put the iat in the EGR location if your intake has a block off plate. If not, right in front of the TB.


good luck, this is just a few of many tips you'll get.
