I have a 1st gen b16 in my 88 CRX Si and I just installed it about 4 weeks ago. Now my 3rd gear syncro)S1 tranny) I believe is going to crap. Before it grinded very slighty at very high rpms but now it grinds going into gear at 4k. So Im assuming it is the syncro. So my question is 1)what part(s) do I ask a dealership for when rebuilding this tranny or 2)what is a good place(and what tranny should I look for..S1 J1 Y1 YS1)should I go for. Ive been told to try to find a YS1 which I beleive is the 92-93 USDM GSR tranny? Or does anyone have a good grind-free tranny I could take off their hands? Any help would be appreciated.
