High RPM shifts, W58 or R154?

[supramacist]

1st off. It's blatant blasphemy what you speak of..

Adding toyota parts to your mits will NOT raise it's value, and you really only disgrace our beloved toyota by bastardizing the 2 seperate entities.

That being said. The r series tranny is what you want.
The redline is at 6k on the w series.

You should expect 7k rpms to be the max revs for safety on these trannies.
And 7k may be pushing it. But if you set it up right.

The r series would do what you want. Not the w.
