I finally flipped my engine over to a 1.6 L turbo and I was using a VAC/Boost gauge to monitor the brake booster but now it is on the turbo doing boost duty.
I run an AutoMeter gauge, 2 1/16, white face with black numbers and a red sweep needle. It is illuminated and seems to be well made. As for instructions, I am pretty sure it came with something more than the classic four boxes with illustrations in them and no words. Not sure of the price but thinking somewhere in the 30 to 33 range.
Some gauges do not come with the 1/8 inch nylon tubing and the fittings to hook it to a 1/8 inch threaded port. I had an oil gauge for the turbo that had me buying a separate kit for that purpose. So watch if the gauge comes with hardware or you will be down to the local parts place buying a kit.
