Changed mine to a Mishimoto unit that opens at 60 celcius. Its pretty sweet.
I hope you have a water temp gauge. My stock gauge wouldn't even move until its too late, it would stay at the middle, while my Defi gauge kept pinging like crazy, 3 to 5 times. At that time I just bought the car and I thought it might be the water temp gauge was not working properlly. When I heard the gauge going off again, my stock gauge crept up bit by bit.

The thermostat when worn out, tends to open earlier, sooner... it's designed too, it mainly consists of wax and a spring! My old school understanding!
Usually in an s14 to s13 engine swap, the cluster temp sensor is neglected and that causes the gauge to read wrong. It could also be a worn out thermistor (the single wire temp sensor for the cluster's temp gauge)
You could verify the temp with consult or an after market gauge.
None of that really matters if you still have air in the coolant system
Which doesn't sound like the problem either because it'll take longer than 5min for the engine at idle to reach operating temp. So I think you're not overheating just a faulty temp sensor.
Sorry for all that just had to address some bullshit in the mix first!
