I'm doing an engine rebuild now, and while i have to motor out, I want to add a knock sensor. I did some research and didn't find a definitive sensor to use, but the bosch sensors seem to be pretty popular. Would this kit work with my MS3Pro (https://www.bmotorsports.com/shop/pr...xoCJpoQAvD_BwE)? Obviously I would have to weld and/or jb-weld a nut onto he block in order to mount it, but that will be easy as I will have the engine out of the car. Bonus question, where would the best place to mount this sensor be?

 

NB sensor ?

 

Bosch KS4P

 

I'm not sure if a stock NB sensor will work on a MS3PRO. I do agree that the Bosch KS4P from Ballenger will work.
There is/was a forum member that had some M10 to M8 studs fabbed up for this. You could also experiment with just using M10 and drilling the sensor larger, but I'm not sure if that actually works or not.

 

Not sure why it wouldn't but it's what Rev and other people recommended for MS3. It's tuned/built specifically for BP engines.

Will the KS4P work in Jspec BPT in the factory spot and would I buy the bollinger kit with mounting hardware or just one of my spare mazda bolts? This would just wire right into MicroSquirt?
