Small frame quick spooling turbo Its going into a heavy 4x4 with 37 inch tires, so low end torque and response is priority, also the space under hood is a little limited . It's a gen 4 4.8 , so I don't have cubes to help spool either . I plan to make 500 hp max, I could care less if it runs out of steam at 5000rpm, its going to spend most of its time around 1000rpm- 3500rpm. It would be awesome if I can get spool and response characteristics like a ferd 3.5 ecobewst. Any suggestions are appreciated .

Garrett GT3582R, perhaps, assuming the 4.8L is basically stock in terms of airflow characteristics? If I'm reading the compressor map correctly, it'll just barely avoid falling into choke up top at ~1 bar boost. I used one on a 4.2L Ford V6 for several years and was pretty happy with it.
You might check out this similar 4.8 / s366 build. https://www.performancetrucks.net/fo...-8-van-539084/
If it were me, I would install a cam suited for low rpm torque production in a 4.8l. @stock48 should be one of the first people to contact about this. Stock48 facebook contact

Something like an old 60mm Garrett would fit the bill nicely, but there are probably even better newer designs. BTW, this is a terrible forum for asking about quick spooling torque monsters. The average response will probably involve a Borg turbo that will be half the size of your motor, along with recommendations for a 5500rpm stall converter. Quick spooling around here seems to be starting to spool at 3000rpm.
Another vote for the S366... Good build showing what they are capable of. (on a bigger motor to boot)

What are you looking to spend? A borg s360/363 cast wheel would be fine. Even some of the smaller 65mm turbine ebay turbos would be fine. You don't need much for the cubes and power you're after.

I have been looking at the s366 , its a good option , I have a lq4 with t4 S475 that spools up pretty good around 2000rpms I start seeing boost. The price is pretty decent as well , do the 68mm turbine wheel with .88 A/r . The only thing I don't like is that its physical size is big but I guess that's why they are reliable , they are built like tanks.
Friend is selling these https://www.ebay.com/itm/Precision-7...EAAOSwdc5bYL-A, but might be a bit more turbo than you need. I'd run the .81 housing for what you want.

S366 would be good.
or at a little more money, maybe a 362SXE sort of thing.
Even stepping up to the larger 73mm turbine probably wouldnt hurt anything at all, and may well work better by allowing the engine to breathe a bit better rather than choking it.

But I'd still prefer the larger turbine side of the 366.
Or these cover both in the SXE range. The 363 with the billet wheel should outperform the regular cast 366 in all areas, airflow and spool because of the lighter wheel

But on price, the regular 366 would be hard to beat.
