What would be best option for a b20b transmission? there are 2 ones i am looking at; 1) gsr tranny with or w/o lsd, or 2) b16 with lsd. It will be my daily driver but i want it to go alittle faster then stock like around 130 mph and possible boost.

 

This is going in an EF right? YS1 cable trans. Ideally a GS-R YS1 (they were also available as an LS tranny, both came in '92 - '93 Integras) The nice thing about the YS1 is hydro guts will swap into the case.

 

Agreed best option unless your switching to a hydro trans, Though if your serious about boost and plan to get crazy a GSR trans may be the better alternative or you may run into traction issues...

 

I was going to swap it in a 1991 crx si. where can you find a gsr ys1? im not gonna go all crazy just wanna tranny that can handle being abit crazy every once in a while.

 

Check the H-T marketplace. Another option is to find a junked YS1 tranny (any model) with a good case and then find a hydro B-series tranny and swap the gearset and diff over, much better option than a crappy cable to hydro conversion kit.

 

Im prob gonna put an integra ls tranny in it. Is there anything i shud look out for with the integra ls tranny?

 

Make sure the case isn't cracked, check for play in the diff and input shaft.

 

ok im prob gonna do the 92-93 integra ls tranny. Now all we gotta do is find it!
