This handy site does Apache .htaccess to nginx configuration translation and should help. Near the top of what it generates should be a Location / line. If this file was located in /torrents then you will need to update it so the rules are applied only to that directory.

tnx ryanpq , but i use that convertor and is old and is not good .

i use this conf

autoindex off;
location /torrent/ {
if (!-f $request_filename){
   set $rule_0 1$rule_0;
}
if (!-d $request_filename){
   set $rule_0 2$rule_0;
}
if ($uri !~ "^/index\."){
   set $rule_0 3$rule_0;
}
if ($uri !~ "^/$"){
   set $rule_0 4$rule_0;
}
if ($rule_0 = "4321"){
   rewrite ^/([^/]*)$ /?page=$1 last;
}
rewrite ^/([^-]*)/([^-]*)/$ /?page=$1&act=$2 last;
rewrite ^/upload/([^/]*)$ /?page=upload&act=$1 last;
