some of the aftermarket intakes position things a bit differently. anyways, if you wnt to change the way it is. all you have to do is take of the 6 hex screws on the cap rotate the port to where ever you want it to be and screw it back into place. solved.
as far as 1 or 2 springs go...i just put the smaller back on, so now im running both springs. i have to say TWO springs. i noticed the car didnt feel as strong on the top end with one spring in. i finally got off my lazy *** and put the smaller spring back in, and it feels great up top again. i have a slight slight flutter on low low boost. but i think i can fix that tomorrow morning.

i have used a stock 03 valve, MR valve & Greddy type-S & am now running a Greddy Type-R with a Pressure bypass valve made by "MAC" aka "Dejon tools Leak Stop Kit"
i have virtually zero surge, quick reaction from the valve on partial lifts & i have tested the valve to hold 36psi before cracking & it requires roughly 45+ psi before the crack starts to leak any signifigant amount of air
under 15 psi the lower port of the BOV is active & allows the underside of the diaphram to see pre-throttle body pressure/vacum...but once manifold pressure exceeds the limit set by the "MAC" valves refrence, the lower port of the BOV is vented to the atmosphere, making the valve function under high boost similar to an oem valve that has beeen modified to block the pre-t/b pres/vac refrence, without any of its negative side effects such as slow partial throttle release & slight surge under high load, low rpm operations
some links
http://evo.dejonpowerhouse.com/ you can get the same pressure bypass valve here, along W some good info & test data.. check under BOV-Misc-Tools for the Pressure bypass valve AKA "leak stop kit"
