Go for it. I too am a mechanic/technician. I bought mine 7 years ago. I paid $5,100 for a 65,000 mile 86 GN. Body was excellent, paint was fair. I was told it had a blown head gasket. Knowing nothing about these cars, I blindly tore into it only to find the head gaskets were fine. So, now that the heads were off, I sent them out for a basic go through. I changed the cam & lifters, did all the recommended upgrades to the engine. New fuel pump, hot wire, etc. After talking to a bunch of guys on all the GN sites I could find, I replaced my turbo. That was my smoke problem. I now have over 175 time slips on this car, tranny went bad last fall. Installed a rebuilt Janis tranny this year along with a turbo & injector upgrade. Havent gone to the 1/4 track yet but I did run it at a local 1/8 mile & matched last years best. You sound like you have plenty of mechanical ability. That along with the guidance of sites like these, you'll be fine. Welcome to the dark side, enjoy the ride!!
