Which b20 is high compression

Any engines OR Transmissions 5spd 6spd lsd, etc. Engines and transmissions must be installed between the warranty period. We are not responsible for any modifications done to any engine. The year is located just above the fourth exhaust runner. It is in a circle with a slash through it. Disregard the slash as it means nothing. You must also look at the month it was made. Again, it is right next to the year and will have the month in a circle with a slash through it.

This is a general rule on all honda motors, but the month is not always there. If a motor was made in 98, but was made in november or december of that year, it is actually a 99 motor. That is because they start making the motors early for the next years vehicles. They have the same valves, springs, valve covers, distributors, cam gears, etc. There is one exception however. Of the many B20 powered vehicles, three of them came with the P8R head, and only in certain model years.

The Orthia, which came out in was one. The other was the Step Wagon. The orthia came with the P8R head in it's model years and the step wagon came with the P8R equipped B20B in it's model years. The P8R head is a completely different casting than P75 heads which were used on all other B20's. Delivery times may vary, especially during peak periods.

Of the many B20 powered vehicles, three of them came with the P8R head, and only in certain model years. The Orthia, which came out in was one. The other was the Step Wagon. The orthia came with the P8R head in it's model years and the step wagon came with the P8R equipped B20B in it's model years. The P8R head is a completely different casting than P75 heads which were used on all other B20's. This head came with 84mm combustion chambers and 33mm vtec sized intake valves. All B20's have a knock sensor, regardless of where it comes from, which signifies the high compression 9.

If your B20 does NOT have a knock sensor, it is not the 9. High compression B20's use "PHK" pistons which have a less of a dish them, as the "P3f" pistons found in the low compression B20's do. All B20's have an 84mm Bore and an 89mm stroke regardless of year. They all have an 81mm combustion chamber diameter as well, except for the "P8R" head, which has an 84mm diameter and larger valves, as described above. Which is more torque than they are rated at to the flywheel.
