I am planning on putting a Livernois turbo kit on my yukon to make it more fun to drive at highway speed and make it tow better. I usually tow about 2k but have towed 5k a few times. With only 2k it tows great, but 5k it almost stays in 3rd gear. I dont plan on doing alot of racing with it, or upping the boost over 7psi. This is my family ride and since i sold my cummins its also my tow rig. I want it to last 150,000+ miles. With a safe tune and normal driving/towing will the turbo last that long? I have almost 9,000 miles in the 1.5 months I've had it so i rack up miles quick. The turbo itself shouldnt wear out right? I know bushing turbo's last forever, how are the ball bearing ones?

Before anyone asks, I use only mobil1 every 5k miles and regular maint. like religion. It has the stock tranny cooler but i think I will add a slightly larger one, that should make it last 200k miles with fluid/filter changes every 35k or so.

I dont think you're going to have an issue. I had similiar questions a couple years ago when I started modding my Tahoe. If you actually stick to what you are saying I dont think you'll have any issues at all. I was so worried about my motor and trans lasting, but Im now putting in a 6.0 and 4L80 anyway even though my 85K 5.3 and pretty much stock 4L60 are still fine. If anything I would worry about the trans. You are definately going to need a huge tranny cooler and I think a shift kit would be a good idea as well. If anything will kill it, it will be the towing, not the turbo.

Go with the Radix

it puts drag on the engine at low cruising rpms where a turbo can run a full 7psi at 1800rpms without having to downshift. Even a roots blower with lowend isnt capable of low boost or as much low tq under strain.

It is all going to depend on your maint. I would suggest making sure it is tuned properly and you keep up the maint. I do not see any improperly installed/tuned FI system changing reliability over the long term. Just remember with any power adder, it will find the weakest link faster than a stock motor.

The only problem I see is that Livernois recomends against towing. With my STS kit I see high EGT's which might be a turn off for towing. If I were to do a straight family rig to tow with it would be the Radix.
