I'm looking at LM4 swapping my s13 hatch, and I'm trying to do some research into what kinds of gauges I should have on my dash. It's going to be a n/a build, so boost gauge isn't necessary. Someone has already recommended a wideband guage, but that's about it. I think I may also throw a volt meter in the mix as well, as I'm going to be running a sub and some other electrical stuff. Does anyone else have any suggestions? I'm new to the whole gauge game. And if this is in the wrong section, let me know and I'll move it. Thanks!
