Long Term Durability, DAILY Driver Turbo Comparing prognosis for LONG term durability at the 500 horsepower level, daily street driven.
Project is a heavy vehicle tall gears, old man driver . 5.3 Liter Suburban 4WD with 3.73 gears.
Looking at the following similarly priced Journal Bearing units:
AGP Z2 Billet 6565S
VSRacing 70/70 Billet T4
BorgWarner S364.5 SXE super core with aftermarket housing.
.
. ANY of these stand out as better or worse ?
Any particular one of these units that you would NOT want to take on a 7 Thousand mile road trip ?
I see rebuild kits for the Borg are easily available for only $145.....Anyone know if the other units are rebuildable ?

FWIW , 04 6L vs 7875 pump gas, by all calculations 600 rwhp , 4500 lbs on the street, , over 20,000 miles on a 180,000 m engine. 2 full hrpt . DD for 7-8 months of the year ( Canada) you can have it all - cheap , fast , and reliable- of course all those things have different definitions to different people . Build it - drive it
Kurt Urban had over 100K miles on his turbo truck.

Borg will be the best durability wise no question. But I run the billet 70/70 on my cammed 5.3 and it’s an absolute blast on the street and I’ve spun to 6000-6500. Night and day difference over a billet 78/75. I’m in boost by 3k but that’s bc my converter flashes to that. I would think a 65/65 could be interesting but you would be fighting RPm and backpressure. Rebuild kit for the 70/70 is $60 so if abs when ur dies, pull it abs rebuild It in a few hours and be back on the road.

It will spend 90% of its life in transitional throttle scenarios where a small turbo will react quickly and shine the best.
