5sfte
i've been hearing different things with this 5SFTE. one is i need a map sensor and need to put in check valves, and the other is that if i have the map sensor i wont need the check valves. so someone who knows about this shit help me out because i dont know.
i think what they're trying to tell you is that if you use your stock map sensor you'll need check valves to hide it from seeing boost....or you can get a map sensor from a turbo'd MR2 which is designed to work under boost...
