JTFM is correct for the 97-02ish model years, 03/04+ used a JZFM and the stall speed is identical. I use these converters in cars running down to the 12.0 mark and have never had one bad. I suggest and do use these because they are reliable and dont cause problems, not because I want to up-sell something that isnt required and could potentially cause problems. How many guys do you read about blowing up a stock torque converter? How many guys have problems with aftermarket converters? I have a pile of bad converters from 4T65Es here that are aftermarket from various vendors and not a single stock replacement that has gone bad, this is about 6 years time worth that I have used Precision of New Hampton conveters and I have sold and used several hundred of them in that time frame. There is no reason for a higher stall speed if you cant go WOT from a stop with full traction, it just makes traction worse and slows the car down at the track. The stock converters stall to 2800-3000 in most M90 cars even with basic bolt-ons which is more than plenty and on a dyno the torque is typically already near peak and going down around 3500 rpm.
