I am gonna do a light build on my 03 wrx. here is what I am going to be adding
-Grimmspeed ported exhaust manifold and crosspipe, and uppipe
-vf48 ported by grimmspeed
-cobb 3" bellmouth catted dp
-considering a grimmspeed ported intake manifold
-TiC composite TGV deletes
-DW injectors, about 650-750 cc
-walboro 255 fuel pump
its currently got some unknown aftermarket turbo inlet, and a lightened flywheel with stage 2 exedy clutch. I got it compression tested a few weeks back, and got 148-150 on all cylinders.
I am also considering a water meth kit, maybe an electronic boost controller, and a lightened crank pully.Is an upgraded oil pick-up needed? and also what about an intercooler water sprayer?
