well, after my first time drifting, I want to get my ass in gear to do things to my car that i've wanted to do for a long time.

I'm looking to get another car for a daily driver so I can do a lot more work to my 240.

What i've got:
91 240sx SE 5spd
basically stock with only an intake.

I want to clean up the engine bay.

Move battery to trunk, fab a short intake to fill empty battery spot.
Remove all emissions things from under hood.
Remove clutch fan, install larger electric dual fan.

So my question is, what all can I remove to gain power, reduce weight and on a small budget while I save up for that swap?

Do I need the AIV, EGR, SCV, carbon canister, etc...

Will my car run like crap if I do remove these things?

I know I saw these things done to other cars, I think Hachibill has all of these things done, I just wonder what all is involved with this.

Any help would be appreciated!
