Hey guys,
2000 civic sir, (b16a) bought the car with a hydro locked engine(bent rod.hole in the block)
so i put a 88-90 jdm b16a in. After hours of searching and trying everything i have no clue were to turn. when you start the car it dosent start smooth it starts like a motor mount is missing (its rough), idles where it should, no fluctuation, exhaust sounds like its a light misfire (makes a poping noise), the engine hesitates under 2600rpm but after that its totally normal. NO CEL.
I bought the car with, megan headers 4-1, skunk2 intake manifold, cat back magnaflow. Everything was swaped over such as, intake manifold,headers, oil pump and crank angle sensor(the one on the oil pump)

Here are all the things i have done, valve adjustment, new plugs and wires, coil, cap and rotor. Ignition timing is set at 16deg, double checked timing belt marks, compression test turned up 180 and 160psi x3, cleaned iacv, i have unplugged the o2 sensor to see how it preforms and it just ran rich, carb cleaned the throttle body.

When i pulled apart the nfg engine i cleaned everything that was needed in a varsol bin and then washed in soapy water, dried then reassmbled.

I have put on 650km on the engine since the swap. I have searched everything on the net, any help would be awesome.

What might be happening is the motor is on the edge of not being able to run. As the RPM rises, the compression and heat levels increase as well, making combustion easier. Check the spark at all four wires to be certain it is ok, check and clean your grounds and then check your fuel pressure at various RPM's. You may want to check the TPS and MAP sensor voltages as well.
