just like it says honda tekkies

 

Define "better."

The J1 has shorter gears, but no LSD. The YS1 has an LSD, but it won't hold up under slicks very well. I'd just get an S1 or a J1 (very similar gearing).

 

this is the n0n lsd 93 gsr one so its not worth getting if i have a j1

 

the ys1 has shorter gearing. it acutally almost the same as the usdm type r gearing but without the lsd. the ys1 also has a shorter final drive. great for the track but not on the freeway. i know from experience

 

why wont y1 hold up under slicks?

 

my ys1 has been the difference in more than a couple battles with 94+ gsr's. i beat them off the line and they catch up going into third then i can usually pull them by the top of third. i'm puttin in a typeR lsd this winter and new synros. i love this tranny. the best cable tranny IMO. although highway cruising sucks. i try to keep it below 4.5k, which is around 75-80 mph, so i can save gas. its good for speed though. the car pulls strong up to 135 before i get scared of losing my lisence. thats all i know about my tranny.

 

anybody know where I can find a ys1 with an LSD?

 

japan

 

good luck finding one, it took me 4 months to get one. imo it is the best tranny i have had with the lsd that is.

 

Just get an s1 and put a quife or a phantom grip in it. I would

 

J1 is better then S1

 

Havent driven any other cable B16 trannies, but I loooooove my J1 tranny. Its so fun railing through the gears. Third and 4th are really strong and pull all the way to 8 grand with no hesitation. Heres a couple random rpm / speed for you

4th gear 7500k = 105mph fun fun
5th gear 3k = 50mph
5th gear 4250 = 70 mph
5th gear 4750 = 80 mph

If you cant get the LSD go with the J1 very good for city driving.

hth,

 

The JDM S1 and the J1 are the same.

13.250
22.052
31.416
41.103
5.906
Final drive4.400

The JDM and the USDM YS1 are the same one....so that means if you have bad syncro you can use USDM 92-93 GSR trans parts.The YS1 new from Acura cost 3200$ canadian.

13.307
22.105
31.458
41.107
5.880
Final drive4.400

The J1/S1 ratio were taken directly from the Japanese Honda site since every site here put the gearing from a ITR or 99-00 Si

The only difference between the USDM and the JDM Ys1 is the fact that in Japan you could get an LSD with that one.

 

You are partly mistaken when you say that a JDM S1 and J1 are the same.

The JDM S1 and J1 do have the same gear ratios...BUT, they do not share the same final drives. I do not care what you have read on Katman's or any other sites. The S1 has the 4.440 final drive, where the J1 has the 4.266 final drive. Basicly the J1 is a S1 tranny, with the final drive of the Y1. On some J1 trannies, you will notice (if you'll got a keen eye), that a S1 ID sticker will be on the case, but somewhere close by will be an ink stamped J1. The later model J1's just had a J1 ID sticker.
I know this to be 110% true, as I have rebuilt quite a few JDM Y1, S1, and J1 trannies for myself and few others. Don't believe me?...then split a J1 case, and count the final drive ring gear...then count the final drive ring gear of a S1. The S1 will have 63 teeth, and the J1 will have 65...just like the Y1.
Currently I am using a USDM GS-R YS1 with a LS 5th gear and a Quaife LSD, and I'll tell you that it has been...and still is the best cable tranny I have ever used. I have the quickest 1st thur 3rd, with a long 5th (for that highway mileage).

Perfect. That is the only thing i would change about mine. Is a longer 5th gear for highway driving.

 

I just find out that YOU are wrong!

I've got a J1 and my bro got a S1.Whe have the same acceleration.Whe have the same rpm at cruising speed.
I asked someone who have access to JDM parts(Live's there) and he told me to not let anyone tell me that J1 and S1 have different final drive.

Btw,I am not considering any info on any site for gear ratio....well,not for the J1/S1 'cause they don't have the right number.
I took mine directly from the Honda site in Japan.

You may be a good guy or a good trans guru....but as far as the final drive for the J1/S1.....you are wrong.

With 15" in 5th gear @120km/h the motor is running @~4600rpm.

There is no way I would be so high in a 4.2 final....

Someone may have change the final drive in the transmission.


Do your research!

 

i believe this guy. he's got actual proof of opening tehe damn things up. the other guy only has a speedometer to back him up hehe

 

to actual firsthand experiance.

 

THIS!!! is the whole reason don't post, and I tend to keep my info to myself.
I do all my homework using real trannies. I don't care what you think, or where your boyz live, or even what your sqeeze's speedO says...Until you open a JDM S1, J1, Y1, and a USDM S1/A1, and any of the YS1's...not to mention the 94+ hydros...then I think you should shut your PHUCKING mouth and stop phucking it up for the people who really want to learn.

Someone just got ******* told....

I can also back his claim up of the 65 teeth on the final gear drive on the J1 trans.. I have takin a few apart myself, and I just double checked in my garage the tooth count.

I agree with these guys. The best possible source of information is first-hand experience. I have learned a lot just by doing my own swap. to all us who do our own mechanical work.

 

you guys got any hints where to source a YS1 lsd tranny?
im in need of one
