My 3rd and 5th synchros are gone in my H22 tranny. I'm looking for like a performance rebuild kit cuz by December I'll be pushing over 300whp and I don't want my tranny to fail. I figure that rebuilding it will be better than getting another used one. Who makes kits like this for our tranny?

 

you won't need it, not for 300whp, there are guys with over 600whp using basically stock H22 trannies

 

Do they have anything special inside the tranny? Where can I get good synchros other than the Honda dealership?
