I have not. I can't afford to spend $400 on something until I know for sure that that's what actually needs to be replaced. I'm waiting on a new fitting for the coolant line behind the turbo that is poring out coolant. Once that's fixed I can actually let the car safely warm up and see if the sound goes away any.
I did, however, grab a few minor things from the junk yard.
I've been trying to clean up the interior. Overall I'm happy with how clean it is, but it's the tiny things that have really gotten under my skin. One thing was the side mirror controller. Mine was worn out looking, and even though that's something 9 out of 10 people would never really notice, I didn't like it. So at the junkyard I grabbed ones out of a 90s 200sx and an 02 Sentra along with their pigtails. Both fit just fine, but I couldn't decide which one I liked more, so I wired in both:
Original controller

Sentra left, 200sx right

Sentra

200sx
I stuck with the 200sx one for now, but if I decide I like the Sentra one, I'll just throw it on. Wiring was simple. All but 2 wires had the same color.
Also I've recently decided that I'd really like to have fog lights again. I still have my factory lights, but they won't fit with the intercooler piping. Bummer. At the junkyard I came across a really clean fully loaded 98 Sentra SE. It really upset me that the car was there as it was super clean and would make a very nice DD. It had the factory fog lights on it and I thought they might fit to I grabbed them. I took a picture with them sitting in place. I have to make brackets for them but I think they look great:
Other than that, the car has just been sitting and waiting on that fitting. I also scored a 96 grill last night for 20 bucks. I'll post something when I finally figure out what the problem is.
