Trying to put a b20 with jdm gsr trans into my 91 hatch. Have all the mounts but missing some bolts, and now my mind jk. What i need are the size and lenght of the three bolts that go into the trans and engine to hold the rear brackit to the engine its self. I know it is not a M12-1.25 it is too small

 

im doing a b20z with a jdm gsr trans myself. what are you gonna do with the little vents from the speedo gear housing?

 

I have a jdm gsr in my 91 sedan. I was missing a bunch of bolts too. I just went to the junk yard and found them in an integra. As far as the tubes on the spedo sensr, i just left them open. And it does not leak

 

Would love to find an integra that has not already been gutted like a fish. Got a hydro GSR trans with limited slip and a 98 b20. What year integra rear engine bracket that is the bracket between the rear motor mount and the engine itself do i need. As well as the bolts that hold the braket to the egine itself.

 

any bolts from civic accord or integra will work!!! so u can get the rear t bracket bolts from a civic and is just fine good luck

 

If you are talking about the rear T bracket, then you have to use one from a 90-93 integra for the EF chassis. I tried using the one that came with my gsr and played hell for a whole week trying to get it in. The DA integra one fits right in. As far as the bolts go get the ones for the gsr trans. I found out that the bolt holes in my gsr trans were slightly bigger than the ones from the DA trans. You will have to open up the two bottom holes in the T bracket but its not hard to do

 

Got the right T braket then. What about those bolt sizes?

 

Dont ask how i figured this out, LOL...., but the bolt is the same diameter and thread as the oil pan drain plug. Then the length is the same as the rest of b series bolts for the same place.

 

it fits! lol i am not surprised honda loves to use the same size bolts every where thanks
