so i am building a somewhat high performance 22re engine, high pro head w/ 1mm over sized valves, 270duration/.430lift high output rv cam, cyls. bored .020 over, short ram open air intake system, stage 2 racing clutch, and big bore 4mm oversized throttle body from LCE. ive been told that all these mods are going to require mods to the fuel system as well. si is this true and if so what upgrades would i need to perform. would a high performance fue pressure regulator take care of it? any help is greatly appreciated thanks guys.

 

if you want the most out of it.. run megasquirt. The factory ecu isnt' designed for performance.
