Suspension/Tires/Brakes first...especially since its an auto, you're gonna get a lot of haters, so just prove them wrong by handling better than them.

 

you know what you've been alot of help along with a few others but i'm thinking about selling my integra lately it seems like the fun in my integra has been squeezed out i'm thnking about getting vr6 somehow i'm not as excited as i first was about modifing my integra i have 3 more honda civics at the house and a lexus ls 400 personally the integra is a great car and i love it but it's time to move on automatic just isn't the move

 

id say swap the auto for the manual trans as well. i dont hate autos, they just suffer a little when it comes to acceleration because of the differene gear ratios and such. Manual will be a lil bit faster and of course much more fun to drive. Since a manual swap is kinda expensive and u havent done anything to this car i would seriously consider looking to trade that teg for a 5 speed. then after that i would go in this order.
Suspension
I/H/E
intake manifold
lightened fly wheel
cams
cam gears
fuel rail
etc etc theres a shit load of little things u can replace.
At this point if you go FI obviously u want to replace the internals and you also want to get a chip (Hondata is ur best bet there)

also wouldnt be a bad idea to get aftermarket axles (if ur gonna be pushing a lot of PSI with FI)
