I'm very content with just a vf34 and support mods. It's plenty quick for me, really reliable, and a very usable power band for the street.
There's obviously much faster cars, but for a DD it's tough to beat. I get a little over 20mpg city, 26.5mpg on freeway, and can hold my own on the track. I've run the turbo setup on the car for 80k+ miles with no issues.
Sure more power would be fun, but the 6spd does a lot to cover up the lag. It's pretty easy to keep it in the meat of the torque curve. And honestly, triple digits come so quickly it's more than enough power to get in to trouble.
