So a bit of an update,
I got the second vehicle I was looking for. A 2000 Nissan Xterra XE 2WD. It'll be my daily driver/camper while my 240 will become my project/weekend ride.
Also, the sh*t calipers from O'Reilly's resulted in a brake fluid leak after I installed them. No, it wasn't the installation that resulted in the leak. It was the fact that the washers included with the calipers were basically useless. I didn't have the time to go back in and fix it myself, so there's $223 down the drain.
I'm also thinking I'm going to delay the SR swap, since I don't think I can get the money together anytime soon without eating only Ramen and sacrificing my entire social life. Thus, I'll probably be moving on to other things in the meantime.
Including the Silvia front end swap, adding an after market exhaust, and possibly an aftermarket steering wheel.
I'll keep this thread updated with anything I do.
