Hi Martin, so did you ever get any order and shipping confirmation from Collette?
The Ebay auctions for TB's for the 4G63NB engine were interesting, in that there were aftermarket/larger diameter ones avail. for less than the stock used ones. The aftermarket copies you would add the stock missing pieces to, like TPS and IAC. Being as these were popular performance engines, many add-ons and hop-up parts exist. I'm used to modding engines lacking aftermarket support, or having to comply with smog laws restricting what can be done legally, that's how I got so creative to begin with.
And yes it's good to look locally, to get used to seeing what is available, I bet shipping to SA isn't cheap. I've been trying to find more info re: this engine and TB. IT's confusing, this engine family has different versions, esp. with the differences in performance and emissions systems. IT might help, to research how Mitsubishi's engine code numbering system works, each letter/number has a meaning. I still don't know what the NB at the end stands for, the 4G63 seems to be fairly broad application.
