Great article! Thanks, I've looking for information like that for some time.
I've been emailing this guy back and forth asking questions about the upgraded RB25 turbo. He actually sells 3 different stages of upgrade for this turbo.Stage 2 and 3 use a completely different compressor housing so you don't lose the compressor efficiency like the article describes. He does, however, bore out the turbine side. The article says this isn't as bad, but still not the best practice. He didn't talk about cliping the turbine, and I doubt he does cuz he's putting a whole new turbine wheel in it.He says higher stage turbo has more lag, but also more power. But he won't commit to saying how much power its capable of.
