JDM Style

JDM styling is also another big aspect to going to JDM. We will bring you some information on JDM parts for styling as well

Different Types of B18C Engines:

b18c engine

The B18C transmission comes in many different engine codes and is hard at times to determine which one you have; Y21/Y80/S80/S4C/S9B/N3E. Now you will find more of the Y80 and S80 versions typically before you will find some of the more exotic but less known transmission codes.
For sure you need to make sure that you are getting a Cable or Hydraulic transmission as well as determining if your engine has an OBD 1 or OBD2 wiring harness connected to it. Typically you can look up your year of the engine you are buying and get this type of information. Making the change form OBD1 to OBD2 can be a pain.

The guys over at JDMCars.com provided us some info on B18C transmission data:

B18C:
S80/Y80 (Optional LSD)
The transmission found in JDM GSR's is very popular and overall an excellent transmission. For all motor and boost applications this transmission has excellent gearing and a stronger differential compared to its B16A and B18B counterparts. The transmissions with LSD should have "LSD" stamped on the casing and to make sure, inspect the differential and use the parameters I described before to identify whether or not the transmission really has LSD.
Here is a look at the specs:
1st: 3.230
2nd: 1.900
3rd: 1.360
4th: 1.034
5th: 0.787
Reverse: 3.000
Final Drive: 4.400

B18C1:
Y80
This transmission is found in all USDM GSR's. Although LSD was not offered these transmissions are still highly sought after because of their stronger differentials and optimal gearing. For those not interested in ultra-short gearing this transmission provides the perfect balance between acceleration and top end.
The specs are the same as above:
1st: 3.230
2nd: 1.900
3rd: 1.360
4th: 1.034
5th: 0.787
Reverse: 3.000
Final Drive: 4.400

B18C5:
S80 (Helical LSD)
This transmission is one of the best B-series transmissions Honda has offered in its vehicles. Every gear has dual synchro's and the gearing is perfect for all motor applications. Plus, LSD is standard and will be stamped on the housing. Look to spend soem dough for these transmissions because of their quality, LSD, age and gear ratio's. Finally, if there is some question about whether or not you're S80 has 4.4 final drive or 4.7 final drive you can check the transmission housing. The code "4jhd" means 4.4 final drive was offered as original equipment, while "ne3" signifies 4.78 final drive.
The specs are below:
1st: 3.230
2nd: 2.105
3rd: 1.458
4th: 1.107
5th: 0.848
Reverse: 3.000
Final Drive: 4.400

B18C (JDM Type R):
S80 (Helical LSD) JDM Type R transmissions are the best for all motor applications where acceleration is emphasized most. All 98 and up JDM Type R transmissions came with 4.785 final drive with the same 1st, 2nd, 3rd gears as the USDM Type R. To make highway driving more tolerable, the 4th and 5th gears are the same as GSR transmissions. These transmissions are rare because of their final drive.
Here is a look at the specs:
1st: 3.230
2nd: 2.105
3rd: 1.458
4th: 1.034
5th: 0.787
Reverse: 3.000
Final Drive: 4.785

Now that you are armed with lots of information about the B18C transmission its time to get to swappin.
