Hello just bought my first love, a 1986 GN w/ 43k on her. I am modifying the car little by little. Sorry but I could not find the "SIG" as I am having trouble on takeoffs (but that is for later). I live in Mobile Alabama. Served in the 1st Gulf War in the USMC. Now I work for a Telephone co. So far I have upgraded to 60lb injectors (I wish I would have gotten bigger - for later use) & a turbo chip. I also purchased an adjustable wastegate actuator & an boost controller. also had to buy a windshield washer pump (I had to get my girlfriend to put the assembly back together [lol-my hands are to big]). I am fixing to upgrade the fuel pump w/ a hot wire kit.
