6.0 Turbo Help Hello,
I am new to the site and know there is a lot of information on here and this topic has likely been covered. I am rather uneducated on turbo sizing, and what makes a turbo work well with a particular size engine. I also am not sure how to adjust turbo sizes for different applications.
The build I am currently working on is a 6.0 ls (4.005 x 3.622), the engine will have forged rods and pistons, a cam, some 317 heads, and an Edelbrock tunnel ram. It will be EFI and I am attempting to make 900-1000 flywheel horsepower. This combination will have an air to air inter-cooler and be on race gas with water injection (meth injection is not allowed)
The main reason I decided to start a new thread is because this vehicle won't be used for drag racing, it is going in a used for land speed racing (more specifically Bonneville). Most of the posting I see on this site are about drag race cars, which I am actually way more familiar with that the LSR stuff.
My thoughts on turbo was something in the 80-88mm range that would be capable of 20-25 pounds of boost. My target boost range is around 20 PSI because I figure that will become the point when keeping the head gaskets from kicking out will become difficult. Unlike most of the drag race guys lag won't be that big of a deal for this build since I have five miles to get up to speed, but that presents the problem of being wide open in boost for 5 miles and I need a turbo that can handle that.
I am operating on a budget and do not want to speed $3000 on a turbo, what is your guys thoughts?
I appreciate any feedback I get and sorry for the long first post!

An S484 billet wheeled unit should do what you're after without blowing a ton of hot air. Don't cheap out on an intercooler, this will be important running wide open for that long, at least water injection is allowed as it'll help cool the charge.

I have read that a lot of people are running an S480 on stock cubic inch 6.0's. Would that be a good choice?
What are the advantages of a billet wheel over a cast wheel? Strength?
What company should I look at to buy the turbo from? Clearly I need someone who has good customer support!

I used a cast S480 all season on a 6.0L and made 888hp/1004tq at the tires on 18psi.
Recently ordered the S484 due to stepping into more cubes. (408)
I am not too familiar with the LSR stuff but I would think the S480 would do what you need and sustain a budget.

A billet S480 with a 1.32 AR'd T6 will keep back pressure low (which is important for those long pulls) and still efficiently work with a 6.0 at those power levels. If this is within your budget, I still recommend the 484, it gives a bit more room to grow. Billet wheels are lighter, and work more efficient than a cast wheel. Even a cast-wheeled T6 S480 would be a great match if you're on a tight budget.

^^^^^^^What he said. . I am running a billet s475 t4, on a ls2 but I never take mine to the track. A t6 would be good for them long pulls. . I'm in southern co and h&d motorsports here in town has a 69 camaro they are building for the salt flats. They plan to brake a record in there class . Good luck with your build

Thank you guys for all your input. I am have talked to a few people I know who know a lot more than I do about turbos and I have heard a lot of people recommend the s475 or the s480. I will have to do more research on what will work with my application the best. I am on a budget and these options seem very budget friendly, but I also know you get what you pay for and I don't want a turbo to fly apart when I am several thousand miles away from home.
One thing I know for sure is I don't want to run out of turbo. If I can't set the record I want to have the ability to keep turning up the boost until the record is mine, or the head gaskets give up the ghost!

The Borg Warner won't fly apart they run the s400 frames on fleetrunners that go cross country. .. yes there the best bang for the buck not necessarily a budget turbo, mines from bullseye so it's a little different than the box Borg Warner, mine has t4 housing and billet but I don't see why you couldn't start with the cast s480 t6 and upgrade it later if wanted

I would go with a big turbine, you're going to be generating a lot of heat and need to keep it moving in the right direction.
As far as compressor, go with an S480 at the minimum, that'll be enough to support 1200 flywheel if you can keep the IATs down. From there I'd go billet wheel or even billet S484 if you need it. 96mm turbine with a 1.32 A/R T6 housing, or even opt for their 1.58 A/R housing.

Billet wheels tend to be lighter and more efficient. They'll spool sooner and generally make more power for any given size. There arent really any downsides.
Given you are a long duration runner, I'd be happier err'ing on the large side with the turbo, rather than the small side as lag or throttle response shouldnt be an issue for you.
