I have a 99 Civic Si and will be pulling the tranny soon to install a JDM ITR Final Drive and a CTR LSD. At the same time I would like to replace the 1-2 and 3-4 synchros, since I am getting sme grindage. I can get a great deal from Len, but he works at an Acura Dealership.
I was under the impression that the Type R and Si trannies are the same, minus the LSD. Is this true and are the synchros interchangeable?? Please no guessing, I really need an answer from someone who really, really knows for sure. Thanks a lot.

Go to hondaautomotiveparts.com and get the part number for the synchros.

Now go to acuraautomotiveparts.net and get the part number for the ITR synchros.

That should help ya.

 

I have done that, and those web sites use their own numbering system. Which to me, means that just because 1 is an Acura and the other is a Honda, then they get different #'s. But that is just my way of looking at it.

Anyone know if they are the same ????????????

 

i have heard that they are the same as well (except LSD). i saw it in another post maybe like a week ago, completely forget which one though. do a search you'll probably find out the answer

 

I'm sure they're the same except Acura will be far more expensive.
