Oh yeah, I also want to point out that there were several things with my swap that didn't go as planned.
I don't know where I heard it, but I swear I remember seeing that GVR4 motors were a direct swap, electronics-wise, with 4G61T cars. That's definitely not the case. The CAS has a completely different connector, so you need to use the Mirage one. The O2 sensor is two wire, so you need to use the Mirage one (which is 4). As stated earlier, the coil pack has a totally different connector, so again, it's easier to use the Mirage one. I also needed to cut the TPS connector off the Galant harness, and splice it onto the Mirage TPS's harness. Also, the igniter is totally different, so you have to use the Mirage one. The ECU was completely plug-and-play though, which was nice. I'm sure I'm forgetting something.
I totally came into this swap thinking it was going to be way easier than a 240SX/SR20DET swap (which I've done 5 of). It's pretty similar, but I just ended up REALLY taking my time, and replacing a lot of things on this motor that I don't usually do on SR swaps (but probably should). I mean, this motor has 5 stinkin belts! (timing, BS, and 3 acc). But I think in the long run, I'll be really glad that I went a little OCD on the seal replacements (front main, rear main, etc, etc, etc). I also put anti-seize on almost every bolt, cleaned the crap out of a lot of stuff, and tried to make every modification as bomb-proof as possible...without dropping a lot of $$$$ (I used scrap metal to make at least 3 different brackets for various things along the way).
Anyway, thanks for reading! I'm going to be driving the car to Tampa tomorrow, which will be almost a 500mi trip! YIKES. Hopefully everything will hold up!
