I have a HX35 turbo. when I bought my Banks stinger plus it came with a quick turbo exhaust housing, big head waste gate and promised quiker spool ups. It has delivered on that promise but for the life of me I cannot find any specs on what is differant than stock except for the actuator(set to open around 34psi), and the opening for the waste gate(almost twice as large as stock). So I know I am not stock but cant seem to find any info any where as to what the differance is. I have not called Banks, but was wondering if any of you knew what is differant between it and the stock housing. Banks says it will not work with an HY, just an HX. I was very naive when I bought it and I guess I still am today.
