When I was investigating turboing my 2zr-swapped Yaris, I made inquiries at Monkey Wrench racing and Turbokits. The impression I got from those outfits is that the U340 is good for up to 275 HP crank. Frankly, I would be very surprised if it could handle that much power. There was no mention of torque capacity. I bought an SAE paper on the U340E. It gives a figure of 150NM as the capacity which roughly translates to 110 ft/lbs. I expect that's just based up on what the 1.5 produces and does not represent the max capacity. I am not easy on mine, though I don't do burnouts and I installed a thermostatically-controlled fan and cooler. Even under boost the fluid stays in the 180 - 190 range and I have detected zero slipping. I do change my transmission fluid a lot more than recommended, not that it needs it but I like to give it the best fighting chance. Sometimes the shift might be rough when downshifting from OD. I like to manually shift from third to forth as I can keep it in the power band better and it makes for smoother shifting. Sorry, for being so long-winded, but I thought I'd give you my experiences with the trans.

Did a last minute look over yesterday as well as an oil & plug change. Car is set for drop off for tune the weekend of June 1st. *crosses fingers*

*edit* the wiper arms where installed incorrectly by the shop that worked on it last. They have been swapped since this picture.

IF I'm their most definitely. I'm dropping it off Friday. They have the call all weekend. I'm still working so chance that I might not see it and or don't forget it's a ground up haltech tune. Then I gotta break everything in.. 😂

So I'm guessing it's like my friend's C6 Z06 with a supercharger. Base tune at first. Drive around for 500 miles or so to break everything in, and then go back to retune with higher psi???

Exactly, I have an engine, 1.5 Way Differential & clutch to break in.

So it'll be more than 500 miles to break everything in for you
