okay, heres the deal. I have a 93 LS and my synchros are off a bit, so if i try to shift at a high rpm w/o double-clutching I grind the gears a bit (especially bad going into thrid). I thought about a transmission overhaul until I was told that that could cost like $1500ish… and I dont have that kinda money right now. I thought it might be cheaper if I just got the synchros replaced, but I see that still being very expensive.
Then a friend of mine told me about this place in Illinois (Soko International I think it was…) where he got a new transmission for his toyota really cheap and he said they had lots of acura/honda stuff too. I tried to find their site and failed. So I am contemplating buying a new tansmisson one way or another if its not too expesive (I use expensive very loosly here). But I thought it would be awsome if I could drop a tranny from a 93 GS-R into my car. So my question is, how much modification would I need to do for this, or will it bolt straight on, or is it a waist of time. What would you recommend because I don’t want to grind my gears and I am still pretty slow at double-clutching, so I would like to fix this… PLZ HELP. thanx
direct swap. any b series tranny will work. theres not modifications. if u can find one then great. if u want the tranny from a usjdm b17 then just get a s1 or j1 tranny cause thats all it is if u want an ys1 theres two types a lsd an non. the lsd will be alot more but worth it.

sweet, good news. i just looked up the price on a website… and I might not be buying one…lol. I’ll just have to look around for some good used trannys. thanx for the info
no problem.

quoted “direct swap. any b series tranny will work. theres not modifications.”
wrong, b series cable clutch type will work, hydraulic ones will not.
also, another thing to take into consideration is the year of the tranny because if your planning to use your old clutch, or if your planning to buy a new one, or if you just want to get one to match your car’s year so next time you or someone else does a clutch job, they dont have to worry about checking up on what year the tranny is…
90-91 & 92-93 have different teeth counts on the clutch disc/input shaft. but flywheel & pressure plates are the same.
certain trannies such as the S-1 and Y-1, and J-1 have the “small shaft” design which means it has a smaller diameter input shaft than the YS-1 transmissions. from 1992-2001, ALL b series transmission (usdm) have the large shaft transmission, but the 1990-1991 B series transmission had the small shaft transmission. so find the code, and make sure you get a cable actuated clutch, otherwise you will be kicking your ass in the future.
yeah i have a 93 and im not gonna get an older tranny so, no worries. thanx though
yea its a direct swap if u get the year. he has a cable tranny hinch hes going to get a cable tranny to swap in. hes using a 92-93 clutch so it has to be that way. im pretty sure he knows about the splines and the diffrences. so like i said direct swap if the years are the same. other then that u have to buy a new clutch but still it will work without problems

I have a question… What in the hell is that?
FYI the B17A1 was not an option in JDM Tegs. The XSi came with the B16A.
G2White - As stated above, you will want a 92-93 long geared YS1 if you are happy with the gearing, performance and MPG you are getting now. You can install the YS1 short geared trans, but there will be a trade off. Lots of guys will say they like how it gets you up in the RPMs quicker, but you loose ~2-4MPG, you will have a slower top speed, and a beefier left leg from working the clutch pedal more often.
If you come across any G3 trans you like, you “can” use it, but you will have to do 1 of 2 things:
- Buy an expensive cable to hydro conversion
- Swap all the internals of the hydro trans into your 92-93 YS1 case with a little grinding (search on this).
im a jdm nut. i have a habbit when saying something thes american version i say usjdm. the b17 is the gsr motor. 92-93. also came with a ys1. i figured he new what tranny went to each motor. my bad. i know the xsi came with a b16. i have one in my car.
josh
92-93 didn’t also come with a ys1, it ONLY came with a ys1…the RS/LS/GS has a ys1 long geared tranny, and the GS-R has the YS1 short geared tranny. ALL 90-91 RS/LS/GS (only models available, no GS-R) had the long geared S1
Can someone give me some more “in-depth” information about the differences between long and short geared trannys? So far, Ive got you go through the gears faster with a short, but is it like sooper fast or what? How big is the dfference between the trannys? I know redline for my stock (long geared I suppose) tranny in 2nd gear is 52mph, with the short geared would it be lower? like maybe 40? 45? (not looking for a specific #, just reference) How big of a differnece do you think it will make?

I am a bit confused. Say I get a b16a engine from an Integra XSi and the transmission that is mated to the block is the S1 transmission - would I just have to worry about which clutch (90-91 clutch vs 92-93 clutch) to get in the future while still being able to use the same axles? (axles used from the b18a1 to the b16a/S1 tranny)
I hope I made sense in my question. Basically can the axles for a 1992-1993 Integra work with the S1 transmission?

G2White heres wat u should know.
With a shorter geared tranny u can fly faster through ur RPM band quicker than the long geared tranny.
Also when u shift ur rpm will drop less than the long geared, like in the long geared when u shift from 2nd to 3rd, it drops u out of ur power band but the short geared tranny will keep u in it.
and yes 1st to 2nd is like 0-40km/h but in the short gear its probably like 0-35km/h or less. Its noticeably faster and it will make a difference. Someone had a built LS with a long geared tranny and ran 14.6 and with the short gear he ran 13.9 so alil more than half a second faster which i think is a big difference. Plus the short geared is alot more fun to drive.
sweet, thats what I wanted to know. Thanx man.
This is not that hard to find. I am sure there are several more you can find for comparison: Click Me! and scroll down.
There is a lot of over-“hype” about a short geared trans. The performance improvement is all relative. In general terms: For a given engine with a wide, mid range of torque/hp, a long geared trans will generally work better for that application. For a given engine with most of it’s power in the upper RPM’s a short geared trans would be better.
Without knowing anything about someone’s engine setup, it is useless BS to just post something like: “Da shortz gears iz roc’n yo.”
well, in your oppion then would a long or a short geared tranny be better for a stock 93 LS motor?
IMHO - with your stock engine, stick to the stock long geared trans. There is a reason Honda/Acura used the YS1 (long gear) in the 92-93 RS/LS/GS. The stock non-VTEC engine is a low to mid range engine. It doesn’t make much sense to rev the piss out of an un-modified B18A/B or B20B/Z engine.
Now if this becomes an “off-road” vehicle, all bets are off. At that point do what ever your hearts desire. For a “street” car though, I can’t see swapping in a trans that will lower your MPG (~2+mpg), lower top speed (if you care), added stress on the engine of the higher RPMs, etc… If some people get wood from the faster rev’s and quicker shifts then so be it. All of the short geared Honda trans were built to take advantage of a high rev’ing engine, and a stock B18A/B or B20B/Z is not it. Head work, valvetrain, and a stout bottom end (on a B18A/B or B20B/Z if done right) can be a good match for a short geared trans, otherwise… waste of time & $$$.
alright good to know. and considering I can no longer get a hold of the guy that was “supposed” to sell me the gs-r tranny, I think I might just replace the snycros in the one I have. I will probly cost less to go that route anyway. And according to what you told me, it would be better to stick to what I have anyway. thanx man.
if ur after performance in the near future u’ll regret using the long geared tranny if u had a chance to get the short geared one.
