Damn!!! Thanks I'm not really planning on doing the driveshaft route .I wanted to know because there was a seller on my IS who was selling his trans that had the valve body upgrade and sprags done for $1,250 and I wanted to buy it . Hell I might as well just get my trans beefed up instead.
Yeah I was debating the exact same thing a few months back. I don't want to settle on vb/sprags alone, so I want a full build. I have a used GS tranny with the vb upgrade sitting in the garage, so I'll probably have that built in the future.
The SRT vb/sprag upgrade is like $800 plus shipping both ways, so I think you are better off getting yours built.
