Hi,
I should have been a little clearer, I am able to get the 3 turbos i mentioned at a good price so i had not considered the 8474. so if i could only have the options of the 8374, 9174 or the 9180 would you say the 8374 would still be the best and how much in on boost response would i loose going to the larger 91 size turbos.
Cheers,
Neal
