alright so im doing an engine swap in my civic and looking at some b series(cuz my d series blew up) and a couple people have told me to get a b18 head the ls and a b16 tranny, i know about engines and which do and which dont but i dont know what trannys are better then others, a little help please?

transmissions are generally the same. B series trans will only with on a b series engine. Same goes with a d series trans...will only mate with a d series engine. Only variation is the gear ratios. Generally they will come complete with the engine...just make sure the listing says "tranny included" in the posting. Make sure you post complete info on your other post so people can help you make sure you got all part you need for your swap (year/vehicle)

B16 has shortest gears ls longest, gsr in the middle and itr I think is almost the same b16, different final drive and lsd

mrspl92

my car is a 2000 civic coupe and i want a b16 the si engines but the b18 have alot more torque so someone told me to put a ls head on a b16 trans im trying to find a b swap for decent power not like the d series and for as good as a price i can find

I mean this in the nicest possible way, but it doesn't seem like you know too much yet. I would recommend doing a lot of reading and research before diving into engine swaps/building. I wouldn't do an ls-vtec if you haven't done a ton of research because they can be very unreliable if not built well. Check out the B18C, best bang for buck b series period.

I was refering to posting your car stats in your other thread, as others were asking. How much into turning wrenches are you?

B16 OR GSR period.
LS gears are disappointing especially with a vtec motor.

Thats right. B16 and ITR trannys are the same except the FD. That FD does make a world of defference though. Some b16 trannys came w/ lsd, some did not just depends on the part number. NO gsr trannys in the states (usdm) came with LSD.

USDM ITR and B16 have the same FD. 98+ JDM and some UKDM ITR had a 4.785 FD with GSR 4/5.

98civdx

Usdm itr has 4.4 final drive and b16 has 4.2. They are not the same.

Nope. B16A2 has 4.4.

Comments Only tranny that has a 4.785 final drive.Nice n' tiiite! non LSD
FYI...
99+ Si coupe and 94+ LS share the same final drive - wacky! All 'R' trans are LSD equipped. SiR models have optional LSD. US GSR are non-LSD.
JDM SiR/SiG has optional LSD. non LSD. Excellent gas mileage though! Same gearing as 92-01 hydro SiR/ITR/CTR but in cable form. Optional LSD. Y1's have optional LSD. non LSD non LSD

*debatable disclaimers
• There is noteable bickering on the net about the S1/J1/Y1 B16 transmission gearing. It mainly revolves around the 5th gear. I find it a waste of time to whine over the 5th gear being too tight or too long of gear. Big deal - it's only 5th gear! My tranny specs were gathered from the Revspeed civic/integra bible(s).

The 4.266 final drive is a debatable spec. If you look in a Helms manual for the 99+ Si Coupe, you will see that 4.266 is the final drive spec. Eddy Lin has found that to be false - he physically took a 99+ Si tranny apart and counted the final drive teeth which calculated to a 4.40 final drive ratio. So, yeah..it's debatable, but I believe it to be a 4.40, even though the Helms manual could be (and probably is) wrong.

• According to my resources, the Y1 + YS1 cable tranny's, are the only two that came with optional LSD's in Japan.

• There's a debate over the 5th gear ratio, in the J1 transmission. Whether or not it's a shorter or longer ratio gear. I personally don't care, but what I have up on here is what I believe it is, and what I've learned from my sources..
Not that it's a big deal or anything....

• US market did not receive any LSD equipped cable tranny's.


• ANY B-series tranny (cable & hydro) will mate up to ANY B-series engine block: B16A/B17A/B18C1+5/B18A+B/B20.
Just make sure that you use the correct clutch, flywheel, & intermediate shaft when mating the trans.


• Lastly, a lot of people think that you can tell a tranny's gear ratio by the tranny code, which is false!.

• The tranny code ONLY tells you what chassis the tranny orginally came from - not what gears are inside of it.

B-Series | Gear Ratios - RPM to MPH/KM Ratio Tests
I had the chance to perform gear ratio testing on some of the B-series transmissions listed below.
Around 4000rpm is where I took note of the RPM's vs. MPH to determine where the ratio's differ between eachother.
Sorry about some of the speeds being KM's. Some of our cars have a Japanese gauge cluster.
You can convert KM-MPH down below at your convenience or conduct your own on-road tests..
Some of you may experience different results in your own on-road tests and that is because of differnt variables.
These variable may include: wheel & tire size, and gauge cluster calibration (honda speedometers are known to be off about +/- 5mph).
The 'BS (Blacksheep) Ratio' was my previous gearing/speed ratios, until my car got stolen!

There is a lot of bad info there.

B16A2 is 4.40 FD. I know this from counting the teeth on every gear of every trans I work on. The 4.266 came from a misprint in the Helms manual.

Any doubt can be taken care of by comparing the B16A2 countershaft P/N to the GSR and ITR.

95skunkedgsr

listen to this guy he pulls trannys apart for a living and probley has had his hand on more trannys then you have touched your own private parts

Zen Chameleon

hehe you said 'private" hehehe

95skunkedgsr

i said something else at first but then i figgured i would get bitched at for it so i changed it
