im doing a swap for this kid i know he was told its a jdm gsr engine. it has no vtec oil pressure switch or a hole for one. what ecu would run vtec without this switch? anyone have any info on this head? i know im going to end up tapping the block but im just curious.

 

JDM engines don't have a VTEC pressure switch on the solenoids. Only a JDM ecu will run the motor with VTEC working and no code for a VTEC pressure switch. You don't tap the block for anything, just run the JDM GSR ECU.

 

so your saying only jdm gsr engines dont have this? were is the swith located or does it not use one.

 

All JDM B-series engines do not have a VTEC Pressure Switch (my JDM ITR doesn't have one either). I won't say all JDM engines don't have them because I'm not 100% sure the D, F and H series don't also. They don't use a Vtec Pressure Switch, just a spool valve. If you run the JDM ECU you will be fine.

 

my b16 has one and its a jdm engine obd0

 

What car is this for?
