jdmgsr1.8

I HAD A B18C IN MY CIVIC AND WAS HAVING PROBLEMS WITH MY HEAD SO I HAD A B16A2 HEAD SITTING HERE. AND EVERY ONE TOLD ME I CAN JUST TAKE IT AND PUT IT ON MY GSR BLOCK SO I DID BECAUSE THE PROBLEMS I WAS HAVING WITH THE GSR HEAD. I USED A NEW GSR HEAD GASKET AND THE GSR TIMING BELT. I GOT THE JOB DONE AND TOOK THE CAR AROUND THE BLOCK TO SEE HOW IT RUNS AND IT RUNS GOOD BUT VTEC WONT KICK IN FOR SOME REASON. I TOOK IT ON THE HIGHWAY AND DID A 3RD DROP AND WHEN THE CAR GETS TO 6000 RPM'S YOU CAN HERE THE MOTOR MAKING A LOUD CLICKING NOISE LIKE THE PIN'S THAT LOCK IN FOR VTEC TO WORK WAS LOCKING AND UNLOCKING VERY FAST. AND YOU CAN NOT HEAR VTEC ENGAGE. WHEN I HAD THE GSR HEAD ON VTEC WAS LOUD AS HELL WHEN IT ENGAGED. SO I NEED HELP TRYING TO FIGURE OUT WHAT THIS HEAD IS DOING OR WAS THERE SOMETHING MORE I NEEDED TO DO WHEN I JUST PUT THE B16 HEAD ON THE B18 BLOCK. PLEASE LET ME KNOW IF YOU HAD OR KNOW ABOUT THIS PROBLEM.

sorry man i dont know much about the gsr or b16 but just a guess arent you suppose to run the b16 ecu when you run the b16 head on a gsr block. check your wiring maybe you have a loose ground next to your thermostat. check your oil pressure too. and check your selonoid. and make sure your car is up to temp too. hope you find out soon. post it up when you figure out what caused this.

ground is prefect and good connection, car is up to temp and i ran the same gsr ecu i have on a b16 and it didnt make a difference ran great. but how can i check the oil pressure on a gsr?

Is your computer throwing any codes?

jdmgsr1.8

no check engine light

What year is the motor and what ECU are you using?

jdmgsr1.8

the car is a 97 civic the motor is a 95 b18c block and a 00 si b16 head, i have a obd2 p72 ecu and a obd1 chipped p28 with the conversion. i tried both of them and it is the same with both ecu's

Have you tried cleaning the vtec solenoid? Is everything wired correctly? (VTEC solenoid and VTEC Pressure switch). The mechanical clicking noise is not a good sign... You need to check your oil pressure

amazing there is no cel

yea i even put the one off my gsr on it and it didnt help, everything is wired up correct. how can i check the oil pressure on a gsr, do i have to buy one of them aftermarket gauges?

jdmgsr1.8

yeah i thought the same thing!!!

^^does your check engine light work? lol
and i am running this same setup on a JDM ITR P73 ECU.

jdmgsr1.8

both ecu's work i can unplug the vtec sensor while the car is running and it will throw the cel then so every thing is working there fine

the only thing i could think of to do just to "check" would be to take the head off and take the rocker arm assembly out and check all of it see if you can see any debree or any signs of damage or anything at all, make sure all the oil passage ways are not blocked
