opinions on mods

Hey guys, here are my planned mods :

1> aos cai (already on)
2> shark 421 header and custom 2.5" exhaust with high flow cats
3> 1.8l elantra cam
4> bbtb and im (have a local speedshop that will match the im to the bbtb for $125)
5> b&g springs 1.5" drop
6> 205/50/15 tires

I want to stay n/a - should this all add up to a pretty good increase ?

And NO I don't want bigger rims. Just wider tires.
