I dont think so. My VR4 RS frontcut had a cyclone intake manifold and big intake ports. Looking at the pics already provided to you in this thread should help you in getting your hands on a thermostat unit and housings to suit. As far as that number goes, I have NFI as its not whats usually found on EVO's, RVR's and VR4's. Maybe Eclipse, maybe NA Galant, maybe Hyundai?
