Message Doing my engine build at the moment. I have 48p heads, and i'm basically wondering, what upgrades or head work I should get done to maximize my potential, or if i'd be wasting my money and that the 48p in the stock form would be ample. Plans do include a 5 angle valve job. Would oversized valves, etc yield to any increases in performance (bang for the buck). Don't know quite yet if i'd be wanting cams or not yet, opinions?

-Stock Turbos (I may consider 530's if Josh sells his one day, but for now, stock)
-740cc injectors (plus 300* fuel rail)
-Ash intercoolers, piping
-Ash inlet piping, selin
-RobZ throttle bodies
-3" DP/TP, inconel manifolds
-Meth
-Carillo Rods, CP Pistons
-plus anything else relevent you find in my profile

This engine build stuff is stressful.
