This question keeps coming up.  No, the k26 is an older design and 
not as efficient, and yes, lag will be unbearable to the point you 
won't want to drive the car; much of the 20vt's design involved quick 
response, and that is what matters to most people in daily driving; 
you're not driving Talladega, or you'd have a turbo the size of a 
tire. There is no substitute here, save a Garrett turbo as some have 
done.  Claus was running a rather large Garett turbo that was far 
more efficient but took much longer to spool.  There is no free lunch.

Yes, boost is limited intentionally by the ECU at higher revs.  If 
you want more power, get a chip.  If you've got a chip and want still 
more power, you're going to have to spend the bucks, and there's no 
shortcut around needing a new exhaust manifold, a different turbo, 
and so on.

costs money, how fast do you want to go?
