. I know of a WRX with 160k miles that makes around that power on E85 and is still on the stock transmission with many trips to the track.
Just accept that they should have designed the car to use the 6-speed as well.
You and I know that the tranny does not usually break the first time it's submitted to a lot of torque/power. It's the repeated abuse that does it in.
The problem is that we don't know the full history of the tranny that they used in that 818.
But, you're right, if it was indeed possible/doable, they should have designed the car to use either the 5-speed or the 6-speed. Alternatively, they could have dropped a built 5-speed in there (gear set, Moore Blast plates, the works).
