It's not intended to, and I didn't say it would. But, you will end up with a car with approximately 100kw/tonne at the wheels, light and nippy with good handling, and the conversion won't break the bank either. What I'm trying to say is that going from a 4K AE71 and 2T TA22 to a 1JZ or 13b turbo is a massive step that shouldn't be taken in one go, rather broken down into smaller, easier, safer ones. Unless it's only going to be a drag or burnout car, a 4AGE will provide more than enough power for fun times. And if you want something more, just drop a GZE straight in, just as much effort for better results and it'll still be relatively sane (plus providing turbo path once you get used to it)
Factory manners mean nothing when you have 200kw in a short-wheelbase 1-tonne car, thats about the same power-to-weight ratio as a HSV W427. For an inexperienced driver, that's tree-hugging potential if ever I've seen it, and I don't mean the hippie-kind of tree-hugging either.
