k20 EG questions

I'm in the process of saving money for a k20a into my EG. I wont do it if I cant bar it so I'm trying to find every possible way I can do this.

I heard that you can use the '04 Accord Exhaust Manifold... is this true? Also, I want to completely change the car to OBD-II ( just because I'm a pain in the ass and I like to do things the hard way) Is anyone able to take the immobilizer off the type s ecu?

any help is appreciated.


oh... and can I use the stock airbox or what?
