Alright peoples
I have never got a striaght anwser from anybody when asked this question. I have a 94(d16z) motor and, i was wondering if i can use a b serier's thermostat into my D16z. Well preffable a spoon or mugen because of the lower oprateing temp that they have. Also i wanted to know if i could use the thermos Fan switch?

They just tell me that the spoon or mugen is ment for the B seriers motor's.Is it the size? If so ok, but if not, them why??

Oh and yes i know their are company's that make 160 degree's thermostats. Its just that i realy want to use a spoon or mugen thermostat. But the most important thing that i really want is to use the fan switch for spoon or mugen.

when i bought a thermostat for my d15b7, it looked the same as my b18a thermostat. call up napa and ask them part numbers and if they are the same then its all good. if the switch screws into the thermostat housing then you can use it right.

the only problem might be is that your car isnt going to warm up all the way because you themo and fan switch are keeping the engine too cool

Thanks man,
but any one out their no a defenate anwser?
