Let's "assume" you are going to install parts. New billet torque converter around $1200 (liketime gaurantee) and $500 for complete valve body. You could get a DIY valve body kit that does same thing as complete valve body, but you have to completely disassemble valve body, make changes and then put it back together. The kit scares some people so they just go with complete body. You need the converter because stock cannot handle any more torque than stock and will slip very quickly. You need valve body to increase hydraulic pressure in trans to keep clutches alive and not slip with extra torque. You can also purchase a completely built trans for around $4000.
