SO i know the FD stock temp gauge with the rotary engine basically had 3 settings, cold, you're ok, and your screwed. with the LS1 swapped in, since it will have a GM sensor, will the gauge be more accurate, or is the desperate need for a water temp gauge still there, like with the rotary? thanks.

 

interested in an answer for this also

 

you cant use the gm coolant temp sensor for the GUAGE. you need to use the rx7 coolant temp sensor. i removed the plug fromt the passenger rear side of the cylinder head and adapted it to that. you can buy a scan guage if you want to monitor the coolant temp via the obd port. I believe there is also a "linear" mod you can do to the stock gauge so it reads smoother.
