B16B (Hydraulic):
S4C (LSD)

The transmission found in the Civic Type R is highly sought after and very rare. Its gear ratio's are identical to that of the B16A's but has a stronger limited slip and dual synchro's in 2nd, 3rd, and 4th gears. Expect to pay between 1000-1200 for a genuine CTR transmission because they're rare and well worth the price. Its also worth mentioning that these transmissions are Hydraulic type.

B18B1 (Hydro):
S80/Y80

This is probably the easiest b-series transmission to find because it's found in every non-VTEC 94-01 Integra. Most notably, this transmission is the longest of all b-series transmissions and has the weakest synchro's and weakest differential. The final drive is 4.266:1 and each of the gears is longer compared to its B16A counterparts. For boost, a lot of people like the gearing of this transmission, plus gas mileage is great and they're very cheap. Look to pay no more than 500 for a clean LS tranny because they're everywhere.

Here is a look at the Specs.

1st: 3.230
2nd: 1.90
3rd: 1.269
4th: 0.966
5th: 0.714
Reverse: 3.000
Final Drive: 4.266:1

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 applicatiosn 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. Look to pay between 700-1200 for this transmission depending on whether its LSD equipped. Also worth mentioning, these transmissions are all hydraulic.

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

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 between 1200-1400 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. Look to spend between 1400-1600 for these transmissions because of their final drive and rarity.

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
