With some further tuning, these N55's with this turbo should perform better than any N54 with stock frames on it, and do so with more reliability.
Garrett blurb on the GTX3076
"GT35R power in a GT30 package and spool. Do you like high boost? this turbo will run in upwards of 3bar without back pressure skyrocketing. A great turbo for road racing on a 2.0 or 2.5L engine, also a good street strip turbo that makes up to 640hp. Dual ball bearing, oil lubricated/water cooled CHRA"
Yes this is in native housings, but these N55's are so efficient we will see very high WHP numbers even with the small housings. "
