I'd go straight 2zz swap if I had a job or more funds, but as my work saw it fit to dismiss me due to my back injury which I got because of their lack of safety on the site, so as a result I'm using what I've saved up over the years to convert to MT, then sell off the HPU, GSA and other SMT bits to hopefully help cover some of the cost.
2zz will be coming later as I want to get some form of work first and i will be getting a few extras on it like the full PPE exhaust and intake plus powerFC ECU, might also get some stage 2 cams in it so I'd rather get it all then swap
Plus apart from the cost of parts for the SMT>MT kit I only need a MT ECU? so I'm already half way to a 2zz swap for later
But saying that if it is going to be too hard to find a compatible OEM ECU for my swap then then I will be selling the motor/transmission/exhaust/SMT parts and what ever else is not 2zz compatible and buying the bits in stages like sweetpete is/was doing, if I go that way you may be able to get those stage 1 cams cheaper and installed already
