i priced out some top end rebuild kits from some online deisel shops and found the pricing was better in kit and package form .(
www.pure deiselpower.com)they have two top end rebuild kits one at $1349 one at $1849 , turbos starting at $1000 .this is for my work truck , i hope i dont have to replace the injectors $$$$$$$$$ .i might get a programmer and do a new air intake if all goes well with the repairs .
