Update:
So today I finished up with the interior of the car. I took some pictures to show you how it looks now. Additionally I also took the car out to charge up the batteries and to put some new gas in the car. I have to say now that I have driven it there are two things I noticed. 1) You can now hear every peppble/sand/dirt/etc that your tires kick up onto the body of the car at low speeds. I don't find this annoying at all because for the most part you don't really notice it once you're really moving. 2) The engine cabin noise from idle-2000rpm sounds the same to me. Not much louder at that range but once I hit give it some gas to 3000rpm+ the engine noise is much more audible than before. I actually love it, imo, it makes the experience more special like it should be because the engine sounds so raw and not muffled. I literally had a big smile on my face when I was driving I think this is one of the best things I've done to my car as of yet. Also a cool thing is when you turn on the car you can really hear the air being sucked into the engine. In regards to the sound system I'm still able to hear it but obviously it needs to be a little louder to overcome the engine noise.
Here are the pictures of the car as it sits now:
Picture of the driver side.
Picture showing what is exposed of the body behind the seats.
Picture showing what is exposed of the body to the side of the seats.
Picture showing the seats and rear firewall from a hunched over height. (You can't see anything has been changed)
Picture showing passenger side.
This picture is taken from right where the seat cushion is. Meaning a passenger wouldn't even see anything at their sitting height.
Picture of the NSX. Just washed it since it was nice and warm out today.
Next project is to remove the engine bay fan and then install my new parts (Type-R upper and lower reinforcement bars + Downforce air scoop)
