Hello my name is Austin, I Bought my first RX-7 4 or 5 days ago, its a 1982 GSL with a 12a. I'm joining the forum because, I'm hoping to get some help with some electrical issues, and some vacume line issues the car has. It does run but... I want it everything to be running right. lol. Anyways here's some pics:

 

Congrats. Had a 81 'S' model myself... fun fun car.
I recommend starting by finding a source to download the Factory Service Manual and changing out all fluids (oil, transmission gearr oil, differential, brake and coolant) on the car for a baseline. Maybe a set of plugs. Then sit and read through the FSM. Have fun.
