Turbo/intake? Where is best place to purchase a turbo? I’m sure everyone has their own opinions on what turbo to run...
im building a 5.3, for a nice street car that will turn up when needed. I’m thinking about going with borg Warner s400. They are little pricey. Anything better for the buck?
also by looking on here, I was going with Holley mid ram, but prolly going with something else because I won’t, on average, be turning the rpms that it’s setup for. Any recommendations there?

HP goal? ET goal, if you're tracking it? A simple Billet 78/75 from VS or ebay (half the cost of VS) will get you more power than most can use, package easier and be more responsive on the street than a BW. BW is a durable turbo though. NNBS intake unless you want to turn over 7000 rpm.

Hp goal Don’t guess I really have a goal? I’m figuring 700hp should be pretty safe number with everything I’m using?? So the cheaper EBay will hold up over time? I want something I’m not having to work on all the time. Is there a certain model number or size that’s better for what I’m wanting to do? I was told to make sure I get one with ball bearings?
any particular intake that won’t break the bank? My pocket is getting light!

If you're ultra concerned about the turbo lasting a "long" time, go BW. That being said many China turbos hold up quite well. And at $275ish bucks, you can replace several for the cost of a BW. I get it both ways. You have to decide. The VS or ebay 78/75 should get you to 700 whp. A BW S475 will definitely get you there and then some. Keeping the turbo sized small enough to be responsive and big enough for your goals is the trick. Everyone gets greedy after a taste of boost, lol. 700-800-900....
Again, the NNBS/Trailblazer SS intake will get you there also. Intake needs to match your RPM range. For a street car, the NNBS works very well for the average guys needs.

Think the ls6 intake will work the same as trailblazer ss? I just don’t like the looks of that intake??
as a neophyte, is there a pile of difference between the s475 and s400 bw turbo? The guy ordering everything was recommending the s400. Buts also 2200. But he said definitely want to go with one with ball bearings..

LS6 is fine, and is on par with the TBSS. Usually $350-400 though. Which is alot for a used plastic intake IMO. You can get aftermarket stuff for not much more if your concerned about looks.
S400 is a "series" or "line" of turbos. The S475 is in that series. Same thing... I'd get a new "guy" personally... seriously... RUN away from anyone telling you that nonsense! He doesn't have a clue. Ball bearing stuff isn't worth the cost IMO. You get very little bang for your buck and $2200 is ridiculous for your goals!
Look at VSracing and his cast S475. It is a China clone of the Borg S475 and they hold up extremely well IMO. The T4 version $429 shipped. He also has a nice S475 billet version that flows a little more up top for $570. That's the unit I'd suggest.

The S475 is physically large, but my preferred turbo. The NextGEN cast 78/75 is The same price and physically smaller and easier to package. It will still meet your goals and is the same price at $429.

What hp rating are these turbos good for?
That’s valuable info.. I appreciate it. I assumed the pricey ones were the way to go??
a lot of money difference between $500 and $2200. The cheap ones hold up for awhile?

More than 700 hp for all of them. If we are talking crank HP the billet S475 tops out around 1000. The newest 78/75 does as well. Yes the ones I linked have very good track records. I've run the S480 from VS for years with no issue so have several people I now personally and s TON of people on these forums. I've honestly never heard of an S400 failure on here that wasn't due to operator error or metal going through them.

Although I was most surprised at how the little precision did given it was tiny compare to the rest, and how badly the China T76 did. Although even if the PTE may have spooled early, even the GT45 made way more power down at 3k showing that smaller units do not always make more power etc at lower rpm's.
The T76 was rubbish though.
Really doesn't matter a millimetre or so out, you can see what he is using etc.

Going by the exh. wheel sizes the turbos all performed exactly as would be expected IMO.

Wasn't a mm off. He said the CX racing had a 78mm exh wheel. CX doesn't make a 76/78. They have a 65mm p-trim wheel. He said the T4 S475 has an 82mm wheel They have a 75mm wheel. He was getting the inducer/exducer confused on some IMO.

And he didnt use a T4 S475 ? He used a T6 S475 from, Summit ?
It lists as 75/88
https://www.summitracing.com/parts/sum-260050
He used 2 "Borg style" units. Both are china copies. FORCED PERFORMANCE "7582" is the typical 1.10 T4 S475 clones. They have a 75/83 exh wheel (some say 82) The other T6 S475 is the summit china s475 clone.
CX has never produced a 76/78 turbo. Even their advertised "q-trim" Which is supposed to have a 68/76 wheel... was only a 65mm wheel in a larger exh housing. I don't believe they ever had an actual Q trim wheel. (even though it was advertised) this is easily seen on their website. Even if they did, that's a 76/68 wheel. So he would be getting the inducer/exducer confused again.

Car's been 9.92@138 with a $429 cast Next Gen VSRacing 78/75
Been 9.76@142 with the Next Gen Billet VS 78/75 (bought on sale for $550, I believe it was)
Both at 15# boost, pump E-85 (usually diluted to about E-70)
At 22#, with a bigger intercooler, and no traction, I had to footbrake it, & went 9.88@146, and 10.00@147
No reason whatsoever for me to even consider a "bigger", or more expensive, turbo...
I run a Dorman LS2 intake and 92mm WARR Performance (Ebay) throttle body... $530 invested in them both together.
I raced and drove mine whenever possible in 2020, and now it's just sitting, covered up, waiting for warmer weather to come back...Never HAD TO really work on, or "fix" anything since going turbo. Anything I have done, has been by choice...ie: bigger intercooler, bigger injectors, bigger fuel pumps, and converting to dual wastegates, which really was the only "NEEDED" work the whole year. (After intercooler swap, the single poorly placed wastegate could not control boost)
My son and I are building him a Fox body Mustang, Holley tuned 4.8 with Gen 2.5 VSRacing 78/75, TBSS/NBS intake, and Turbo 400, and I know it will easily beat mine when it's done....
