i just swapped a b16a2 with ctr pistons in my hb and it starts up fine but backfires after 15 minutes. not only that, my response is really slow, meaning i gun the car and the car does not pick up at all. its really slow (you can run and beat me) does any one have an idea what can be wrong? i searched but could come up with a conclusion.

 

check your timing
should be at 16 degree

 

dudde if your car is not running right, you are not sippose to full throttle it. check the tps sensor.

 

timing is at 16 degrees. i used both types of timing gun (digital and manual)

 

sounds stupid, but are your plug wires right?

 

everything is correct, its just not accelerating

 

Check to see if you're throwing any codes and make sure all your sensors are plugged in correctly. Is your VTEC engaging? Check ignition timing and TPS sensor.

 

wouldn't you lean out with that much compression on a stock map?

 

vtec engages but still no pull. the only sensor not plugged in is the crank pulley sensor, but i'm using a 97 civic ex harness but have a pigtail and am now using a chipped p28 and theres no code. i dont have a obd2 ecu to run with. the sanner wont pick up the chipped ecu. (gynesis scanner)
