Another help me pick my turbo/setup thread - 6.0/80e
So i am close to finishing my kit, and just the important stuff left to go. This is my first turbo build and I am almost overwhelmed with all the info I have been sucking up for the past couple of week, I didnt get viren or Huron Speed to answer me today (no biggie, im sure they are slammed after the holiday) so I figured I would let it all hang out to the masses. This is a budget build, so please dont recommend me a 1200 dollar turbo or something. I am going to sell my NA setup and spend just a little to finish out the turbo setup.
Here is what I currently have or have settled on
Hit me up with recommendations, critiques, advice, and most of all, what turbo to go with??

Here is what I currently have or have settled on
- 6.0 iron block (owned)
- gen 4 rods and pistons (owned)
- ARP studded heads and block, arp rod bolts, arp cam bolts etc (owned)
- going to a stock 317 head with GM head gasket (we think comp will be 9.8ish:1) w/all new valvetrain aka BTR 660, hardened pushrods, upgraded trunion rockers etc (selling my CNC ported 243s that are currently 11.5:1 comp)
- stock ls6 intake and TB (or ls2, whatever i can find cheaper) (will be selling off my FAST 92/92 setup) (UPDATE: ls6 intake and TB PURCHASED)
- aem 400lph e85 pump currently, stock fuel system beyond that (owned)
- Huron speed v3 t4 no A/C kit (this kit is complete, with both downpipes, turbosmart wastegate and BOV, 7.5 pound spring in WG) (owned)
- strong built 4l80e (will handled more than bottom end, no issues) (owned)
- moser 9 inch 35 spline/braced, wavetrac w 3.50s (also should handle more than bottom end) (owned)
- I also have a lot of the little odds and ends. Map sensor, MBC, boost gauge etc etc (owned)
- I am looking at the billet 7875, which i am under the impression will be limited by backpressure on the 6.0, but i like the physical size of it and a lot more people have ran it (UPDATE: PURCHASED VS BILLET 7875 FROM HURON SPEED)
I am also looking at the billet s475 75/83 1.10 ar t4 turbo, which i think will fit the v4 kit size wise, and i think is better for the 6.0, but i am asking because i am not sure if it will even fit the Huron kit without modification (possible issues with manifold setup since its dual feed?), let alone physically fit in there- cam (selling NA cam, just wont work for turbo. i guess cam selection depends on turbo.. again, asking for some advice here) I have looked at LJMS stage 2, or even the very similar summit cam that is 150 cheaper but the same basic cam (UPDATE:Summit PRO LS 226/230 .605/.575 PURCHASED)
- fuel injectors (UPDATE: Siemens deka 80lb PURCHASED)
- Meth kit (UPDATE: PURCHASED)

If anyone has real life experience using a BW turbo on the huron v3 kit I would be interested also, as I cant find any good info if its a straight bolt onto the kit and DP or if im SOL using one

I am interested as well, my on3 7875 is actually a 7665 and is getting some shaft play. I have a virginia speed stage 3 turbo cam and a th400 3000 stall.
I'd love to stick a s480 t6 on it, but really wanna stay t4 and dont need 1000+ wheel. I am contemplating the vsracing cast t4 s475, mainly price, but I believe it should get me to my goal easily. Which is 6.0- 6.50s in the 1/8th in my single cab Mazda pickup.
Not trying to hijack OP, just didn't wanna make a new thread when you have the exact same questions LOL

A billet 7875 will bolt right up to the kit, and make 700whp. For more than that you will need a bigger turbine and a different downpipe for the larger turbine.
for over the 7875 I think it really starts to make sense to look into a billet s480/s488. Ideally with a 96mm turbine.

You guys need to check out the end of my build thread, link in my signature. I just changed from a cast on3 to a billet vs racing 7875. the billet 7875 would not be a bad choice by any means, but be aware that the outlet is undersized by .015-.020 so the 3" pipe will not slide into the housing to make a better seal.
a better choice if you have the cheese would probably be this
https://www.on3performance.com/shop/...harger-1035hp/ <<<<<this one being the more powerful choice i think
I think i'm gonna sell my billet turbo and get the above
or this

I wonder if the on3, the huron speed, and the VS billet 7875s really turly are the same turbos, because if so, they would all have the outlet sizing issue.
I am looking at the VS racing rather than the on3, even if it is the same exact turbo, built in the same factory, i am willing to pay a couple bucks more for VS service over on3s known slow/bad CS.

If all you are looking for is 7-800whp, a cast 7875 will get that done easily. My junk put down 740/1045 (torque is probably an honest 900). I definitely wouldn't buy 80# injectors though if you are using e85.

Ive actually read all through your build thread and turbo choice thread. I looked at that BMF but i was seeing other people saying that for all the fancy specs its not making any more power than a regular billet 7875. I dont think there is a lot of data out on that thing yet. Also, for the size, I think i can go s475, agan, as long as it will fit. Im trying to determine that before i buy it lol.

well i initially thought they were the same turbos. But I’m convinced they are not. Why?
1) 3” pipe slides into the on3 exhaust housing. Will not fit without grinding the hole bigger in the vs.
2) the bolt spacing on the exhaust housing is different. The on3 turbo has 6 bolts holding the exhaust housing on whereas the vs racing only has 4
3) the casting is different. The vs racing did not line up correctly with any t4 gaskets. It left almost a 1/8” lip on one side because the casting was off. Die grinder fixed that.
All in all, I prefer an on3 after getting a vs racing one. Why? Well I was able to just bolt on the on3 without grinding or fixing anything. After all the raving about the vs racing, I was let down by those two details. I mean who wants to spend 500 plus bucks on something you have to take apart and grind on to make it work as good as a cheaper one did, with no mods?

That seems on the high side of what I have seen. What kind of dyno was this? what was the rest of the setup?
