so my ls vtec turbo runs great until the engine light comes on and it starts to over heat and the boost cuts off. i am running s300 with arm wide band. i haven't had the chance to run the code yet but want to know if anyone else had that problem, over heating and boost cutting off? Second part of the question is when it over heats i turn the heater on and the temperature drops back down. is that bad thermostat ? thanks in advance

 

if you are using hondata there is a overheat protection option, which will not let you boost and also throw a cel. as far as your heater dilemma it just means your cooling system is not up to par not necessarily the thermostat
