I just got a crx with a blown engine and am thinking of building a race car out of it. My friend has a fully built and sleeved b18a1 long block and all the extras that was in his race car. ie: turbo kit, fuel system, stand alone, MSD ignition, ........I plan on tuning it to around 280-300whp

What is the best cable tranny to go with? I had a stock ls with a b16a2 tranny and I think I would max out fifth gear before I reach the end of the 1320(on the racecar).

I'm not an expert nor am I a stupid kid with ideas, I have built a b16a2 that put out 252whp @ 6 psi on a Vortech kit so I have some knowledge but I can always use some more.
Thanks,
Daryl

In response to recent questions about different transmissions I think its important to shed some light into the ones available for our b-series motors. There are many differences between B-series transmissions and I've never found an article describing the positives and negatives of each unit. Below, you'll see transmission codes, the car it's found in, and whether or not it has factory LSD. It's important to realize that Honda didn't make it easy for us to distinguish between transmissions. For example, almost all transmissions found in Integra's are stamped S80. This includes the tall LS transmission and the ultra short JDM Type-R transmission. In some cases, the only way to determine which transmission you really have is to take it apart and count the number of teeth on the ring gear. Obviously, in most cases it's not practical to take your transmission apart to determine which one you have. To be safe when acquiring a transmission, you should identify the seller; try to identify the car and or motor it came with.

B16A (Cable), B16A2 (Hydro), B16A3(Hydro):
S4C, S80, Y80, Y21, Y1 (optional LSD)

As most of you know the B16A was featured in Japan between the years of 1989 through 2001. This engine has had several different transmissions mated to it causing some potential confusion.

First, it's important to realize that first generation B16A's came with cable transmissions. The Y1 came with optional factory LSD and should have LSD stamped on the transmission. Determining whether or not a transmission has LSD is very simple, just look into the differential and see if its opened or closed. For those not familiar with this, you'll either see a set of gears that form a closed cylinder, or you'll see an open differential with a bar splitting the middle.

Typically these transmissions have had weak synchro's in 2nd, 3rd, and 4th gears with 3rd gears crunching the most. Its also worth noting that all of the transmissions minus the Y1 have very weak open differentials making it essential that you upgrade if your putting a lot of power to the ground.

As far as gearing, these transmissions are all pretty short. Here is a listing of the gear ratios and final drive, courtesy of http://www.bseries.net.

1st: 3.230
2nd: 2.105
3rd: 1.458
4th: 1.107
5th: 0.848
Reverse: 3.000
Final Drive: 4.400

In conclusion, this transmission is good for all motor and should bring between 500-700 if its hydraulic while cable transmissions are worth between 400-600. Please be careful that the transmission you're buying doesn't have bad synchro's because a lot of them have been beaten on and this is the first problem you'll have. Plus, if you're making a lot of power, 170 to the wheels, be prepared to replace your differential because these can be broken with regularity.

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.

B17A1 (Cable):
YS1

This transmission is found on the rare "blacksheep" of b-series motors. The most important feature here is that its cable-type. This means you can bolt this into any 93 and older integra and 91 and older civic without having to change to hydraulic. The synchro's on this transmission are still considered weak, however the gearing is very good for all motor applications as its identical to the B16A transmissions. Finally, this transmission did not have factory LSD, so keep that in mind when someone is trying to tell you otherwise. Look to pay between 400-600 dollars for this transmission, although its going to be difficult to find and usually when you do, there is something wrong with it.

B18A1 (Cable):
YS1

Again, you'll see how Honda didn't help us out any with the stamping on this transmission. These transmissions however, are much different in there gearing. This transmission has a longer first and second gear with slightly longer 3rd and 4th gears. The final drive is still 4.40:1 making this a possibility for all motor applications, but not your best choice. You'll be able to find this transmission in 90-93 Integra's and they're all cable-type. The prices for these should range between 200-400 for clean, good working units. Paying anymore is pointless, as these transmissions are everywhere.

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

god loves searching and so should you

 

I was looking for actuall opinions. I have always raced Vtec engines so I am used to 8,000-8500 rpm's. My SI hit fifth gear right before you hit the 1320. This was shifting at 8200 in forth(about 102mph) with the b16a2 tranny w/ quaiffe LSD.

To the guy with the first reply, thanks for the info.

Any opinions on what tranny I shoud use?

 

I would go with either a J1 or S1.

I have a question: do you think you will be above 110 mph before the 1/4 mile mark? That is very quick. Most turbo hondas I've seen trap speed between 102 and 109 mph.

 

I plan on tuning it for around 280-300 whp so yeah it will definetly be trapping higher than 110mph.

 

buy an lsd cable trans. better for all kinds of driving (dran, circuit, autocross, snow).
110? you have a virgin pr3 or pw0 in the car?

 

ys-1 with opt/ LSD.

 

thanks for the replies. I loved the quaiffe LSD that was in my SI so I may just swap out the stock diff. for a quaiffe instead of getting the factory LSD.
