I have a d16z6 ex civic(94). The tranny is show signs of wear and I asked around if I should get it rebuilt or it there another, better performing tranny out there(I have plans to supercharge it in the upcoming year, I have the whole kit, I just want to wait until I get a DD). And a few have told me to get a SI tranny(92-95 SI). I thought they were the exact same transmission? Is there any difference or benefit? Is not, or if so, what would be your suggestion?

 

edited for wrong information.

I thought the Si was geared a little lower? IIRC, it was only in 5th gear or something?

I could be wrong. I don't mess with the D series. I upgrayyed.

 

Used both, and Both feel the same to me.

 

si ex trans are the same
only 96 up trans use steel shift forks as appose to the older ones used aluminum

 

if my findings are correct:

so yes, I was wrong, and BSerious was correct. 5th gear does differ from EX to SI

 

so they are pretty much the same, 5th being very slightly shorter and 5th doesnt really matter anyway. There are gears that people take from the ZC trans and use in the Si trans to make it shorter yet, thats if you want to start taking things apart.

 

for the most part, they are identicle. driving it, there really shouldnt be able to notice a difference.

 

Difference is in the 5th. Get the 96-00 EX. Same gear stronger fork.

 

Thanx guys. Plenty of useful info. I thought there no difference, or very little if any. I bought the SI tranny anyways, it was a good price. Tnax Honda-Tech again.

 

O!! one more question. Is the Si tranny a hydro or cable tranny?

 

any 92+ civic trans is hydro.

 

Please use the SI tranny! Its got the proper gearing for the VTEC, EX trannies are much longer which are not as fun.

 

You are misinformed.

 

Wow ur funny ex and si tranny's are practically the same i think the only difference is the 5th gear...and wat do u mean the si tranny has proper gearing for vtec???so ur tryin 2 say that the ex models dont come with vtec...ur confused..

 

You have just been put into the classification which 98% of honda-tech users are in.
