I was wonder if this OBX Manual Boost Controller Eclipse WRX EVO SRT-4 GTI would work for my car?? and how hard is it to install?

http://cgi.ebay.com/ebaymotors/OBX-M...spagenameZWDVW is the website and i just want to know if it will work for my car

 

to be honest with you i would stay away from the obx stuff i got a obx exhaust yea different product but the balance on it is crap so the driver side pipe is spitting cold air and the passanger side is spiting hot air so in other words its junk and i learned the hard way so if i were you i would get a hallman you can't go wrong with that its kinda expensive but better to pay extra and get the good stuff then the cheap stuff that could break or just not work right putting your turbo and motor at risk. know what i mean?
