I have a 94 DC4 with a JDM B16A and a GSR Cluster. I got the car with the cluster in it, and when I fill up the tank full, it only goes to about 3/4 full on the gas and when my car is fully warmed up it only goes about 2/5's of the way for temperature. Do you think it's something with my cluster? I might just get a new one.

 

You have a dent in the gas tank. You need to check the fluid in your tranny cause there is a crack in the bottom of the housing. Replace the butt conectors on the map sensor plug and solder those wires. Look into a new chassis harness. Those are the only things I can remember off the top off my head.
