You def. want the DW300 pump. Drops right in and big enough to support future mods. I'm using it on my td04 on e-85 along with PE 800cc injectors at about a 50% IDC. I'm right around 250whp with a mildly-aggressive tune. You wont get much more than that out of a td04.
Here in IL we have e85 all over, so its really worth it for me.
