Converter
The torque converter is definitely not the place to skimp. There are alot of good converter suppliers out there. Probably the cheapest way to is to buy a good used one and send it to a reputable manufacturer and have them set it up to suit your car. Supply them with all the info and let them do their job. Trying to buy a converter that wasn't set up for your vehicle is a crap shoot at best and moronic most of the time. JMO.
