Link for those angle rings?

 

He made it with his cnc machine
If some of you are interested, maybe you can ask for some
shipping from Italy is pretty cheap

 

Deezums linked a picture of some. Which I googled and found.

today work.. stock injectors holes are too little for new 850cc injectors.. so it's time to drill..

 

reroute completed..

 

That sensor really belongs in the back boss. Its hardly getting any circulation there.

 

<p>Isn't that the cavity right above the water pump? I thought it got a ton of circulation last time i stuck my head in there.</p>

 

<p>What injectors are you using that required all that cutting?</p>

 

with traditional coolant routing, sure.
with rear thermo, probably a lot less.
there's a reason most of use a spacer and keep the sensor back there

 

Yeah, with a rereoute I wouldn't want the coolant reading temp off only zero cylinders. It really only ever sees chilly radiator water there, plus whatever the mixing manifold adds back.

 

Isn't that the fan switch? Probanly never even see functionality with a stand-alone. Basically serve as a redundant fail-safe.

 

No that's the temp sensor. NB fans are ecu controlled.

 

Subbed for ridiculous awesomeness.

 

I'm getting confused. To be clear, that sensor was originally on the back of the head, right?

 

In my opinion, that location should be fine.

 

You want the sensor to be in the main water outlet that keeps getting recirculated through the motor (aka the one that goes to the heater core)

 

Did not know that.

 

I thought you want to read the hottest place of the head, in fact the oem sensor is located in the opposite side of the main thermostat flow.

 

European NB's 1.6 have the NA 1.6 block, a better flowing head with mechanical lifters and the same eletronic of the 1.8 BP's: cam and crank sensors, ecu controlled fans, even the NB-fl 1.6 are OBD2

 

OEM sensor is in the coolant return hose line, basically.

The rear of the motor is still the hottest point in a stock coolant config, that's why we reroute.

Where you have the sensor now is never a hot side of the head, no matter what the cooling config.
