I'm sorry, what?
6SMT to MT swap is straightfoward, ECU can be any Manual one (except USDM ones with the silly fuel lines/sensors etc.) as I found out. TRC and VSC you will have to do without, but its no great loss, in fact, having no TRC made it MUCH easier to get out of turns into traffic without the 'bogging down'.
I'm using a UK ECU and have had zero issues, apart from a CEL for the post-cat O2 sensor that doesn't exist on ADM cars. Seems to run nicer too. The VSC system is tied into the ABS computer (witchcraft) and is more of a nuisance than anything else.
The only parts that are fundamentally different are the shifter shaft itself and the blockout mechanism for stopping you getting into Reverse in a hurry.
Otherwise, cookie-cutter stuff! :)
