I have a 1976 280Z with an 82 turbo engine in it with the stock ecu and all. I also have a electric cooling fan with thermostatic switch that I can adjust. The engine came with these teal injectors that are obviously not the stock turbo injectors but the car ran at 12:1-14.7:1 AFR when warming up. Now I installed the brown injectors and it idles and cruises at 10:1-11:1 AFR. I notice when I'm driving the water temp needle never goes past half-way, it always a tad below it. Not enough to take it out of cold start mode unless I let the car sit in one place. I know its not the fan also because I adjust the temp higher and it doesn't do anything unless I'm sitting and the temp goes high enough to kick it on.
I like the brown injectors because they're better for when I boost, the teal ones have this problem after a while it just goes lean under boost and I have to reset the ecu.
anyway how can I get my car to warm up faster so it doesn't eat up so much gas. Should I get a hotter thermostat? What thermostat are the turbo guys running? Its summer and its still overcooling O_o. Why is the ecu so picky about the CHT temp when warming up garghh...
