my friend has a 91 civic si with b18a1 swap and he has a gsr tranny behind it... the good thing is the pulls like a raped ape to 105 mph but thats all the fasterhe a can go thats redlinging in 5th gear. i think that the tranny could be set up for some type of auto crossor,auto x racing or something . but if some one out the that knows alot gsr tranny and may have here or encounterd the problem it would be great to here back from u peace......
