I have synrco issue....

On my 89 HF, which has an b16a2 (i think thats the engine code for 2nd gen b16), which has the YS1 tranny. Well when I shift into 3rd from 2nd at a rpm higher then 3, I get a very loud and unpleseasnt grind. This also occurs if you go from 3rd to 5th. I know the 3rd gear synrco is gone, so I was wondering what is a good place or anything helpful when getting a new syncro? Also how difficult is a hydrolic clutch conversion? What is required to do the conversion?

Also is it possible to convert the YS1 to an LSD tranny while I am at it? Any info would be appreciated..

Why do you shift from 3rd straight to 5th gear? Or did you mean 4th? I would just take it to a transmission shop. In my area (Los Angeles) you can get your tranny rebuilt with new bearings and synchros for around $650 including labor. Or you can just buy some synchros and make it a weekend project if you have all the right tools.

No, I actually meant 3rd to 5th. I have to take I-10 everyday to work, so when I wind out 3rd gear I'm doing 80 merging onto the freeway, whos limit is 65...

Any info on how to convert it to an LSD would be appreciated...

take out stock diff, put in new diff. not that easy but a general overview. www.gear-speed.com sells carbon coated syncros. i would recommend picking htem up
