You may reconsider..
How much HP can K26/6 max out? - Rennlist Discussion Forums

Standalone is NOT cheap, and street ask the work and running you go through, I would hate to see the turbo be your limiting factor. It's old technology, old design. There are much easier ways to see 300. The k26/7 from the turbo S wasnt that far off already, and can easily get there. Or there's the Lindsey kit.
If youre going to spend several thousand on stand alone ems, and 1000+ on a raw tune, why cheap out on the turbo? I knew I was going to spend a lot, so I figured I would do it right the first time and spend less in the long run.
