sensor

need to know how to take this off

its a freeze plug all you need is a big enough Allen head bit a n something to zip it off ie. impact gun or something else.

I am curious what that is there for and what would go into it?

why would you need to get into that for?

isn’t that where you would put in a block heater?

the reason i need to take that off is because that is a b16a2 block that’s going into my gsr. my old b17a1 block has a sensor right there .i want to put it on the b16a2 so i don’t have a cel on.

i dont think you need to do that, im pretty sure the sensors you need are already on the B16, you dont need to remove that feeze plug.
the teg tips are a great place for information, this one is pretty relevent to your situation

this link tells you exactly what all those sensors are and you can decide which ones you want to keep and which ones already exist on a different part of the B16 than the LS motor. like ECT and MAP sensor relocation, etc.

good luck, the B16 is a fun motor.

i could be wrong, as youre going from B17 to B16, im assuming the B16 was out of an OBD2 car? we didnt get the B16a2 until the mid-to-late 90s in the delsol Si right?

well right now car is running without the sensor and its not throwing a code.but i got some other codes i have to clear but i need a vtec solenoid first.
