Would you get numbers like this with either of these turbos? Highly unlikely. The hotside isn't big enough for our engines with that big of a turbo. Clark (AZ SCOOBIE) has said it over and over. Doesn't make it gospel necessarily, but he's not the only one saying it. My .02
p.s. Alittle better spool and less power could be had with something like the Dom 2.5r

for the most impressive results i've seen with the stock location 30R's. Post #55
GT52 is what I have and on a 2.5L with 110 and methanol it made 507/510. The GT52 is a 7cm hot side FYI.
