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)
