You really learn more about turbos via the search function on this forum. There are days worth of reading on here. Instead of asking which would spool faster a big azz turbo or a small one hmmm. Just a thought. I would not spend my money on something that I knew nothing about.

i agree, you dont really have the need for twins right now with the fueling you have and both of these turbos are to big for singles as well. Maybe he wasnt trying to be a dick, or maybe he was, who cares, not me! We see questions like this all the time, and for me if i dont have anything useful to add i dont reply, but thats just me. If your dead set on getting a new turbo, a hybrid or a s300g at the largest would work best for the fuel that you have now. The larger s300's (62/65/12 or 14) are the next step up after that but they would not work well at your power level. 425-550hp is the comfort level for these turbos and both of the ones your looking at are BIGGER than that! BTW your gonna need a better clutch first if you dont have one already and a set of gauges, you need to moniter your EGTs with those injectors and pump mods.
