Howdy!  I bought my 86 coupe two years ago from the original owner... she only has 74K miles on her and is about a 9 out of 10, condition-wise.  When I got her everything was pretty much original... I've removed the EGR system, all of the EPA crap, removed the cats, and had the ignition curve and others things changed/removed from the ECM EPROM.  She runs cooler, smoother, and has more power.  This winter she'll be getting headers and a nice aftermarket performance exhaust, along with all new hubs, rotors, shocks, and upgraded front brake calipers to the later model dual-piston type.  I'm also going to pull off the entire intake system and change seals and gaskets, change the valve springs out, replace the valve seals, and replace all of the fuel injectors and the fuel regulator.  Then she'll be ready for some longer trips next summer!

How did you get past inspection with such radical changes?

Looks nice.
