Ball Bearing or not?
Ball Bearing or not? Turns out I am getting slightly different turbos than initally thought.
They will be in a T3 housing, TO4E, 60-1, new style GT turbines. But, I have the option to go Ball Bearing. The manufacturer feels the efficiency upgrade is not worth the added cost and told me money would be better spent elsewhere (under 1k). Everything I ever read told me it =IS worth it. Perhaps its this particular set-up that wont benefit so much. It was explained I can only expect a 1-2 percent gain in efficiency...not the 10-15 that i thought.
Anthing else I should request or important questions to ask before the build starts? Any Input?

You aren't going to have a problem spooling up that turbo with your exhaust volume - which is where the BB will help - spool up time. I wouldn't worry about it either - spend the money on something else, like coating the pistons, etc.

Like the manufacturer said ball bearing turbos arent going to do much for you for such a small turbo as far as efficiency. They are going have a longer life assuming you have good clean oil. I would recommend going water cooled as this will definetly extend the life of the oil and turbo.

a commone mistake is that ball-bearing turbos really help with spool-up time. SOMETIMES they do....but in reality the advantage comes with the compressor housing to wheel clearance. They get to make the clearance a lot smaller which will help with the efficiency of the turbo SLIGHTLY.
That is why he said money would be better spent else where. Also, it is UNBELIEVABLE cheaper to rebuild a non-bb turbo. Go with the conventional journal bearing turbo
