if that fails try a A40D i think there called... out of an RA60 with 22re.. i had one with some of the finns flattened off (higher stall) that was behind a cammed up 18RG.. very torquey motors.. and had the stall at about 2900... not much but the converter was only touched a little bit... the guy had the 18RG in a KE55 or something like that, and told be it used to almost lift the front left wheel.. he said the suspension was at full extension when it left off the converter!

what are you expecting to run??? you should even consider a 3pd auto from somthing like an RA40 celica.. they came with a 2.0 liter engine.. and actually had a tow rating so they might handle more torque than the 4a 3pds auto.. but for all i know they could be the same box!!!
