So i'm building my turbo setup which will have all of the normal/necessary turbo parts: 57 trim t3/to4e or a large t3 super 60, spoolin manifold, drag piping/intercooler, tial 38, 550cc injectors, pump, and it will be tuned to 275ish whp on my 98 integra b18b.

My main question is, after the setup is complete and installed, what would good supporting mods be later on down the road that will increase power and/or add reliability? some things that come to mind are:
.ARP head studs
.cam gears (maybe some crower cams)
.better (re: larger) intercooler
.valve springs
.maybe get the turbo, manifold, downpipe coated to keep down underhood temps.
.i might get multiple tunes for weather... again 120 in the day in summer and 30 at night in winter would cause

I'm really adament about keeping the air condition as ice cold as possible and the motor reliable. thanks

 

Big radiator, big fan, clutch, and head studs.
