I JUST PURCHASED A 1992 SI WITH A B20B MOTOR IN IT. IT HAS A GSR TRANS GSR HEAD GSR ECU GSR MANIFOLD KINDA REPETITIVE.ANYWAYS I SEARCHED ABOUT THE KNOCK SENSOR WIRING WHICH WASNT REAL DIFINITIVE WHAT I WANT TO KNOW IS WHAT OR WHERE DO I GET THE SENSOR FROM, ANOTHER YEAR CAR OR WHAT? OR MAYBE JUST GROUND OUT THE WIRES? ANY HELP IS APPRECIATED ILL POST PICS OF THE CAR TOMMOROW.

 

if your car is runnin a chipped ECU then u might not need one, if its a stock ECU, then you need a knock sensor from any honda b or h series engine, tap the blank spot on the back of the block with a 12x1.25mm tap then run the wire from the knock sensor to pin D6 i believe. on the ECU.

BTW if you dont wire a knock sensor VTEC WILL NOT ENGAGE

 

i know, im gonna go to the junkyard tommorow and try to get one, what about the secondary butterflies, what parts do i need to run these, there is no vacumn hose hooked up to the diaphram? any help just want to get everything perfect no ghetto crap.

 

i always went with an aftermarket manifold, i hate the stock GSR manifold
