good to hear you know some of your stuff! and that HID conversion is something i need to check out. i found a thread thatll tell you how to do the OBD1.5 to OBD 2 swap. How To: 3100 OBD1.5 to OBD2

as far as power goes if you turbo it you will see alot more power. i mean it depends on what you want really. do you want a reliable daily driver that can crank out 300 whp? or do you want a less reliable car that will make 350+ whp? either way it wont be too cheap...
