Unfortunately for us Yanks, we have little alternative. We only got the RWD CA18ET, not the RWD CA18de or DET, which is why there are some running around here with the 4AGE, which is much more readily (read cheaply) available, ditto a 5-speed RWD 'box for it. It's the same reason it is usually mated with the Corolla rear axle, as we don't have Utes to pirate for the H165. I just saw a CA18DET on Ebay US c/w 5-speed, wiring, turbo, ECU, sensors, MAF, and intercooler. How much? A paltry $1860 AUS (1400 USD), and for me on the west coast, another $400 AUS for shipping. You work out the total. How does it stack up with what y'all would have to splash out? The swap I'm considering would be nearly impossible to certify there (still can't work out why it's anyone else's business what's under the bonnet). You can't do this?
