i just finished my swap.. i have a sII rb25det in my s13. for the cooling, i'm currently running a a fat huge aluminum gtr radiator (had to cut/bend the lower radiator support and drop the power brace things to make it fit) with dual FAL pullers, stock hoses, no ac condensor, fmic, i'm assuming a stock thermostat, and right now running a radiator flush and water mix to clean everything out because the crap pouring out of the motor when i got it was a nice muddy red color..

the thing is that i'm still running the stock s13 gauge cluster (i know that the water temp gauges on the stock clusters are JUNK but atleast they give a rough idea on the temp for now), and after letting the car warm up and even driving it around with the fans on, the water temp needle doesnt even move. today i ran without the fans to see if there would be any movement and it actually went up to 2 bars, but as soon as i turned the fans on it dropped back to the position where it seemed like my gauge is broken.

1) Is my gauge broken? (it worked pretty well with my old motor swap about a month ago)
2) Is my sensor broken?
3) Are my sensor and gauge compatible? if not what should I use?
4) Is my cooling setup that badass and just way too efficient for my own good??
5) Is everything I'm seeing in terms of my temps shown by my gauge normal and RB25s just run that much cooler naturally compared to SRs?

Thanks ahead of time.

Sounds like the thermostat is stuck open or you need to get a thermostat switch for your fans.
