Turbo slant 6 powerwagon

what brand is a good ebay turbo ?
Its really hard to judge Honestly. The little t3/4 hybrids are hard to beat. I see them on there all the time for $150 with an internal wastegate. We have a few kids at work that have run them with success. Are they thousand dollar ball bearing units?...no. but seriously...perfect for a project like this.
Unless you find a used garret off a GNX. Or perhaps a ecoboost unit. Being the t3/4 hybrids are swap ready with common flanges, id try one of those without much hesitation.
