What’s the difference between h22a4 and h22b4 oil pump?
Once you are sleeved, the fact that one is open and one is closed is rather minute. The backs of the blocks are configured slightly different. The oil pans and lower timing covers are slightly different. The crank angle sensor is located in the distributor on a h22a and on the oil pump in the h22a4.
What’s the firing order of a Honda H22A engine?
The firing order is 1-3-4-2. The 2.3-liter version – H23A – was created based on H22A. Together with the family of H-engines, Honda made F-series ( F18, F20, F20C, F22, F22C and F23 ), which was technically very close to H22 and H23.
What’s the difference between a Honda h22a4 and h22b4 block?
The open deck twists like crazy, so I would get a block guard with the H22A4. Plus the H22A4 has fiber metal sleeves. FM sleeves for short if you see that somewhere else online. It means it has a smooth bore rather than a 60 degree cross hatch. So honda supplied special rings with the pistons.
