It should be on that aluminum Holset tag.
I wasn't even gonna look in this thread to be honest. But it's not an HX35, hx35's have a grove for a snap ring to go into inside the intake housing to hold the silencer ring in place and have a snap ring holding the compressor housing on where as H1C's have a no silencer ring and have that big V-band clamp you see by the oil feed line holding the comp housing on.

That's a H1C off a 1st gen with a wastegated housing added on or a WH1c off a 94-early 95 2nd gen. Nothing special about it.

Nice! I think you are covered as far as gauges go, however, you could always go crazy and get a rear diff temp gauge, air/fuel and whatever else you can think of. Keep reading and ask questions if you are stumped. These trucks are a lot of fun to modify save for runaway.

Air/fuel mixture won't help much on a direct injected engine.

That's where the go crazy part comes in. They look cool though...
