Okay, so here's the scoop: My girls RSX is boosted; no ****. Problem is its 15psi allll the ******* time. I want to make it like my Integra's set up with BBG and so forth so she can actually grab some traction and stop roasting off expensive tires.

I took out the WG; TiAL MV-R 44mm gate to find two springs in it. Well, according to TiAL Sport's technical info it should have 3 springs in it; Brown, Maroon, and Grey. I've got a Grey and unknown color (I'm color blind, photo attached.) Now I ordered a 7 PSI spring from ExtremePSI but its Yellow and doesn't fit, so I'm guessing its for the TiAL Q BOV and they sent me the wrong spring because according to TiAL's tech data I should have a Brown and Gold spring.

Mainly, how the $*%K is it running at 15PSI with only two springs???

Its a built K20A Type-S, rods, pistons/valves/retainers, bearings, etc. with a Garrett GT3076R .60 charger, TiAL Q BOV and TiAL MV-R gate... I'm baffled. I do not want to put it back together with A) the wrong spring and, B) not the pressure I'm targeting.

 

Forgot the picture...

 

If thats Grey and Maroon it should be 11.60 PSI according to TiAL's tech data... in which case I would just remove the Grey spring, keep the Maroon spring and run at 5.8 PSI but since its running 15PSI on 11.60 combination it'll probably be more like 10PSI >
