I am currently undertaking a 1 uz in to 1991 hilux 4wd IFS replacing the 22r and g52 5 speed. I have a front sump motor from a uzz31 with the a341 auto, 40 pin x3 ECU and a fully intact wiring harness (not a half-cut). I have got an A343 auto, adapter housing and Chain-drive transfer and electronic speedo/dash from an import Surf. I am having the output shaft of the A341 shortened and the 4 prong speed sensor(?) modified to suit so as it fits back onto the output shaft with out needing the splines on the output shaft to hold it in place( as yet dont know how). I have had the hole in the adapter housing where the speed sensor for the Surf auto was, enlarged to accomodate the 1uz speed sensor(appears to line up perfectly). I have replaced the entire dash console (except for diesel tacho, substituted for mine) into my ute and will use the electronic speedo pick-up located on the transfer-case and hook it into the newer electronic speedo. The fuel pump is a Bosch inline unit(, in future to be fed by a surge tank inturn fed by a supra intank pump). All relays concerned with ignition, fuel etc yet to be sorted out.
