I was thinking about the best turbo for what I want in a car; primarily lightning fast spool with more top end than the current TD04L. I thought about the TD05-16G, but it seems to come on to full boil about 500-800rpm later than the TD04.

So I am thinking that my eventual turbo upgrade could possibly be a "monster" ported TD04 with the 19T CHRA, but I am wondering: Does the 19T compressor wheel have much if any impact on spool characteristics, and does it in fact flow enough more up top to be worth it? I'm afraid I'm having a hard time finding info about this, hence my questions.

I guess another option is the TD04-15G; if anyone has info on that and can explain why it is different or possibly better/worse than the 19T, please let me know.

Thanks!
on a 2.5l a td05-16g6 (aka evoIII,super16) is about the only 'size' up grade worth bothering with IMO (there are other turbos of this size out there but thats what I'm familiar with), the td04 turbine will be too restrictive to make any power worth the $$$ regardless of compressor.
