Roush Which Size & Type of Throttle Body to Use?

I need a little help from you guys on here, to set things straight! I'm interested in pulling my Stock throttle body off my 2000 Saleen S281SC which has the Saleen Series I Blower and upgrading it to a bigger and better one! I've been told by some that I can't go any bigger than a 70mm Throttlebody with my type of Saleen blower and by others that I can use a 75mm TB! So first off, can I swap out the stock one for a 75mm Throttle Body on my Saleen Series I Blower without any modifications to the current (Metal Saleen back of the blower inlet tube????) Secondly, I've been told that Accufab makes the best Throttlebody??? I don't think I like the polished Aluminum look or the upkeep & care it requires, what do people think about the 75mm Dragon Anodized Silver throttle body?? BBK TB?? Professional TB?? I'm hoping I can upgrade to a 75mm TB but please clear things up here, I would hate to drop the money and find out by trial and error! I know someone will have answers on here! Thanks in Advance!
