the americans also get a 323 with the gtx. not sure if thats just a familia or something else.
but ive seen a lot of them on 323gtx.co.uk and mazda323performance.com

the japspec ecu is better but its not a huge gain. and you will ALWAYS have to use petrol with a high RON else you'll detonate. The jap ecu is designed for jap petrol which is 100 RON. 98 is as high as we get in aus.

they do come with a factory intercooler but if you're doing the upgrade dont bother with it, get a nive new big cooler. dont know the stock size buts its small.

gtx and gtr are different ecus. and the hang-ons are different too.

as well as the ecu and loom you'll need .. umm ... an engine.
presuming the engine comes with the usuals : injectors, rail, plenum, throttle, ex manifold & turbo etc etc.
not sure on flywheel and clutch...

definitely try to get a half-cut rather than just the engine.

and you'll need the original wiring diagrams and those for the new engine. there's some wire chopping involved to get the new engine in.

also try to get a new fuel pump but not vital.
