      searched previous to posting. ive had mixed answers. some say yes, some say no. i would like to have all 4 b16 gears and keep my ls 5th if possible. i think it is, i could be wrong, but i thought i read somewhere that you can.

        people swap an LS 5th into B16 tranny all the time. I think all components have to be from the same range of years (90-91 vs. 92-93) .

          sounds good, the xsi tranny is a 90-91, my ls tranny is also 90-91. so would that work?

              so which can i use borintegra, lscase and diff, or ys1 case with ls diff?? some guy on HT told me that the ls case well here is what he said..."only work if you had the ys1, because the s1 has an integrated shift fork design, whereas the ys1 are all independent" duz that make sense??? im doing it in 1 week,

                Ok, in general you can only swap parts w/in years. So you can swap parts in 90-91 trans, and in 92-93 trans. But you can't put 90-91 parts into a 92-93 and vice versa. Obviously there will be some exceptions to this rule, unfortunately I do not know them all.

                I know that you cannot take the internals from the j1 or from your stock 1990 tranny and put them into the ys1 case... it just simply won't work, the shift fork design is different (as well as some other parts). Also, the diameter of the shafts are different, the 92+ trannies are larger, this is the reason for 92+ b series clutches being different from 90-91 clutches. If you want to use the ys1 case you're going to need 92+ internals.

                There is a chance you can use your stock diff, stock case, and use the j1 main and countershafts. But I cannot say for sure. If the j1 diff was OK, but just the case was messed up then you for sure could just swap cases... I'm just not positive if the diffs can be swapped, but my initial assumption would be that they can since they're both from a small shaft tranny and they are the same final drive (4.4). I suggest that you contact .J. he probably knows more about b series trannies than anyone on this board and should be able to help you figure out your best option.

                Now, on a side note.... if you decide you want to sell that ys1 case, let me know. I'm in need of one since my case is broken

                  why don't you just fix your 3rd gear synchro?

                    others have told me that i am better off getting a new tranny. it might cost more or about the same to fis the syncro than to get a tranny. .

                      The cost of fixing the synchro and getting a new tranny are pretty similar, and actually fixing the old one may cost MORE than just getting another tranny (depending on what all you replace and how much labor is). However if you fix your current tranny, you're adding a new part, if you get another trans, then you still have a used tranny. Who knows what condition its in and/or how long it'll stay in that condition. There are pros and cons to both options. Which is better for your depends... Mainly it depends on how much you want to spend (and if you wanna spend it all at once or over time) as well as how long you want your tranny to be in good condition.

                          labor is going to vary from shop to shop.... But really simply swapping internals (assuming it swaps over w/o modification) is really really really easy, so it shouldn't take long at all. If you were familiar w/ honda trannies you could have both cases open and the gears swapped within an hour or so. As I said before... you really should talk to .J.

                                he's pretty busy, but he should get back to you. I believe he's out of town at the moment.

                                            One thing to keep in mind... replace all the pins, clips, etc in your LS diff when you swap it. A pin in the diff tends to crack when abused (speed shifting, dumping the clutch, etc), which is what causes the entire casing to split open.

                                            and for those who care... replacing one synchro vs replacing all of them costs about the same, as many tranny shops order them as a complete set anyway. Many shops also charge a flat rate for labor no matter what has to be done (Eagle Transmission in D/FW is like that.. $485 flat rate for a manual no matter what's wrong internally, plus parts, when I had my Civic tranny rebuilt from a bad input shaft bearing + damaged input shaft + worn synchros.. came out to about $1100 with a brand new clutch and 1 drive axle replaced)

                                              maybe I'm confused (it would be nice if you didn't say "LS" because that doesn't tell us what year the trans is... and thats what is important).

                                              Correct me if I'm wrong, but you have
                                              1) ys1 case (no internals)
                                              2) j1 tranny w/ bad diff and bad case
                                              3) stock 90-91 ls tranny w/ a grinding 3rd gear (this should be an a1 or s1 tranny)

                                              If those are the parts you have.... you CANNOT use your ys1 case. You do not have a set of internals that will fit the ys1 case. Your j1 is 89-91, your stock ls tranny is 90-91..... and thus you have all 89-91 tranny internals. And those parts will not fit into a ys1 case. If you want to use the ys1 case you will need 92+ b series internals.

                                              If the stock "LS" tranny on your car is a 92-93, and thus a ys1. Then you still don't have what you need. You couldn't use any of the j1 internals in that case.

                                                colin-ur right with naming what i have. and a shop said that it is doable. charging me 125 to do the job installed. but thats a homie hookup price. and yes, i have a 90 LS transmission, and the j1 is off a 90-91 integra. i told them all this at the shop and he said i could use the ys1 case. if it duznt work out, then ill post it on here as a trial and error i guess. but if it duz work, ill be a happy kid. for the record...turkey bowl ...i kicked ass today and im feeling the effevts already by the damn mudd. till next time, ill keep u informed

                                                  Well, have them try it if you want.... but its not going to work. If you've ever taken these different transmissions apart you would know that you can't swap a complete set of internals. Shaft diameters are different, shift fork design (and how they're mounted) is different, and there may be other differences as well. Personally, if I was you and I got a "working" tranny back from that shop in which they used the ys1 case and 90-91 internals, I would not trust that tranny. The parts are not supposed to fit together. And if they made them fit...I'd be weary of how they made them fit.

                                                  To me it seems like a much better idea to just see if you can swap differentials. Us your stock 90-91 case, j1 main and counter shafts, then your stock differential. I think that might work, but I'm not sure. Whereas I am sure that the other idea isn't going to work.
