what will be my problems with not using a thermostat?

i did a rotary swap and i don't believe the radiator will be big enough, the truck is a b2000, stock radiator, s4 13b n/a, also no heater system,

just thought not running a thermostat might be better for the moment untill next spring when a can get a dual pass unit

 

Engine temperature will vary wildly depending on how much airflow is through the radiator. This will reduce fuel economy, increase wear and make the car hard to tune.

Pulling the thermostat can also cause overheating at high loads. The RX-7 uses a bypass thermostat which if removed, will always cause some coolant to bypass the radiator. If you really intend to run without a thermostat, plug the bypass hole.

Or just put the thermostat back in, because it won't cause the car to overheat.

 

is the bypass the port on the rear plate below the temp and oil senders?

if so that is pluged already

with that pluged, it should always flow? correct?

thanks
