ok after a while this jdm motor has run great but things are starting to break on it (i figured this seeing as how i do autocross and drag) but anyway does anyone know the prices for these replacement parts?
transmission may get rebuilt fully all new syncros (2nd gear is grinding at high rpm's will NOT go in no matter what i do) all the other gears are fine i just want to get all them replaced because i know as soon as i fix it anotherone will go out

is the trans rebuilt worth it ? how much is a new one with and without lsd
alternator sqeaks when battery is at a low charge is about 180$ at autozone for a new one i think i can do this myself but is there any annoying things i need to look out for when replacing this ?
after these it is back to upgrading it and getting it ready to race for the spring summer and fall just like this year
