Figure this may be a question for a lot of people new to turbocharging any lsx motor same as myself. I have had a lot of discussions between people and some people lean to either side so I have not came up with a real answer for my purpose. I'm in process of building my 94 camaro full cage with a forged 370 lq4. Behind it will be a t56 and strange s60 (gears unknown at this point aiming for 3.55 range) the car will see some street time but most of its attention will focus tword the track. Now I have not choosing my turbo yet as I am in process of building hot side. I have been looking lately for borg waners seeing I have noticed great bang for the buck, and have been juggling the idea of an s3xx or s4xx turbo. I see some have options for t4 or t6 flange. I want to find out which one i would benefit more, If any real difference would be there. As for Ar I've been thinking about 1.10. Hopefully someone more experienced can chime in and set me on the right path.

If you can fit a t6 turbo I would go that route. It will flow more on the exhaust side lowering back pressure

Ive built a couple cars with BW turbos....I would do a s475 with a 1.10 t6 83mm exhaust wheel. If tuned right it should make 1 pound of boost at 2300-2500 and 15 psi around 3500 to 4k. Made a turbo kit for my buddys 4.8 and a s472 with 1.10 83mm t6 spooled at 2500 and a t56 with 3.42 gears. Built a buddys 383 with s480 1.32 96mm wheel and spools 1 psi at 2200 and 15 and 3200. I had the same turbo on my 346 and it was alittle laggy but fun lol 3000 1psi and 10psi at 3800

I agree stepping into the game with the 1.1 83mm t6 is the way to go. Leaves you room to upgrade to the 96mm turbine and 1.32 ar down the road to make big power.

If you've got room for it, go T6 for sure. I'm using a T4 S475 and although its really tight, I wish I went T6 to start with.

From the looks of things so far I should have the room.
This is my ls1 mach up for now so i can build my hot side.

get a crank pulley and water pump on there before you try shoving in a t6..

I don't think they make a T6 83mm turbine wheel. Let alone in a 1.10 ar? Bullseye has what they call a T6 offered with a 83 and 87 wheel, but I don't think it's truly a T6 flange. If anyone has some solid info on this I'd like to know?

The only T6 turbine wheel I am familiar with from Air Werks is the 1.32 AR 96mm wheel you mentioned on the S480.

They make a T4 1.10 ar with a 83, 87 and 92mm wheel.

I would always go T6 with the largest turbine wheel I could possibly get especially with a 370. Big turbine wheel, tight AR housing.

I know several people with them.

I have looked at that page I don't know how many times.

I even have it bookmarked.

It's been a long day at work!

Even then the turbine is the choke point. Won't matter if it's in a T6 or T4 housing when the turbine is still the same size.

I love by big T4 here but just saying it would be a good alternative to a T4 with option to upgrade to the big 1.32/96 without having to change pipes. It has same footprint but downpipe flange moves around a little between the two.

No they def have the t6 1.10 with a 83mm wheel...I've ordered 3 turbos with that setup...2 s472's and s476 with a race cover.

With the t6 flange i have options of 96mm wheel at 1.32ar , 83mm wheel at 1.10ar, 83mm wheel at 1.25ar and 87mm wheel with 1.10ar ... What seems to be the common ar to go by as per turbine wheel

Keep in mind exhaust housing/turbine flow numbers aren't everything when choosing a T6 turbo. The 96mm wheel will flow more, but flow data on those is based on a diesel engine that isn't waste gated and only has that housing to breathe through. Your engine will have a wastegate, which also flows exhaust and can boost high end ability of a smaller exhaust housing. I run the 96mm T6 borg warner housing myself, but because my kit only fits that housing, and I have nitrous to spool it if necessary. If you have the option, go with the smaller T6 wheel or a big T4.

A 1.32 96 mm is gonna be alittle laggy with a t56 but with the rite tune up it will work. A 1.10 83mm will spool great and make good power. You can't really pick a turbo until you gave a hp number. But if you just asking what is better IMO a t6 over a t4....

Give us some details on the engine. What is your target hp and how high do you plan to rev it? Unless some funky info comes back like you also want to auto x I suggest T6.

We offer the T6 in a 83, 87, 92, 96 turbines. From .90A/R T6 all the way to 1.58A/R T6.

Will a T6 housing (s475 83mm 1.10ar) be fine on a 4.8? Ls6 cam,ls1 intake manifold, 862s, T56 and 3.42
