Which A/R on S480Sx3 T4 for forged 6.0 The Garrett GT6 is chocking my car, kind of hit a wall with it due to back pressure so moving to something bigger and better, and the turbos on its way out so its the perfect excuse.
Getting ready to order the turbo, just thought I would ask what A/R I should get, gonna go with the 83mm turbine as this thing is still a street car so I don't want it to be too laggy. I run mostly 1/8th and want to make sure I can spool the turbo good on the line. They Have .90,1.0,1.10, 1.25 housings available.
Setup;
Forged LQ9 364" 9:1
Cam 560/560 220/224 on a 117
317 Heads
TH400 RMVB, trans brake with 3500 stall, foot brakes to 3200.
Lingenfelter daul launch control, one for the foot brake, one for the trans brake,
Strange S60, 3.40s
I realize the PTK will require some mods for this tubo and I am already gathering the materials to do it.
thanks

Whatever it will, as of now the 80lbm siemens will be the limiting factor, Car has 8AN supply, 6AN return, aeromotive rails, boost referenced FPR, twin walboro 255s in the tank with a MSD BAP, hot wire kit,
Custom 3 bar EFI live op system, which I will have to have tweaked again.

Lol so you want to go say 5.7 at 3740lbs with a 220/224 cam with 317 heads.
U can't do it.
I used the 80mm with race cover with a 83 1.10 ar and also a 1.25 87 hot side.
I'm 3250 and I use tfs 225 cnc heads. Best I've been is 5.9 at 120 1.4 60ft.
You need a bigger turbo and the twin pumps 80s and 8an line won't cut it either

I'm getting a S482 Billet from Work Turbochargers and Reed over there said to use a 1.10 or 1.25 on a T4 housing for my 4.6L mod motor and that was with the 87 turbine. Right now I have a GT4276 garret with a T4 and 1.15 housing with a 83mm turbine and it spools very fast. I would get a larger turbine wheel or the biggest AR housing they have in that T4. I think that 83mm turbine wheel is going to choke it up top with a T4 housing. Why not move to a T6 with the larger turbine wheel?

I would be happy to break out of the 6's, but the whole point of me starting the thread was to see if I this would work, mostly I dont want a laggy turbo on the street, I know I can spool a larger turbine rolling in on the foot brake/2step, and getting on the trans break/2 step at the track just dont want to wait forever on the street. I know the 80's will stop the car in the 800RWHP range, I run 93 octane with meth. May step up into the 87 or 92 though.

I don't think it will be very laggy at all with a 6.0L I just saw where you swapped to a TH400. You get the right stall and you don't have any lag at all on the street. I also have a TH400 in my Mach1 and I can go from no boost to full boost in a little over 1 second per data logs. Don't fear it. You don't want something that is going to choke up when you want to turn it up.

IRT turbo has BW Airwerks S480 T6's with the 96mm turbine for 895 plus the ride which is a lot cheaper than the 83mm S480sx3 is was looking at.

That 83mm turbine is way too small.
Go with a 92mm turbine at the very least and a 96mm T6 would be optimal with a 1.0 or 1.10 housing on the T4 and of course the only 1.32 housing they make for the T6.
Everyone always worries about lag or has what they call lag. If you tune it right, put the right cam in it, you will never know what lag is.
If you have the stock pcm still there are several ingenious ways to make the car spool the way you want it to. If needed when the time comes I can help you find these tables and tell you what to do.

Thanks man, decided I am going to go with the 96mm T6 S480, just got to figure out how to fab the downpipe. Going to step it down to a 4" with a cone style transition add a turn down and dump it up front. Probably will weld a 4" header flange to the end of the turn down and install a 4" electric cutout on then plumb it into the existing 3" for street driving. Then flip the switch when I want to have fun.
What are the cam specs? duration, lsa and installed center line?

Would love to be able to go 5" but there just isnt enough room and I dont want a hole in the front bumber/fender ect. All in all I should have about a 4 foot pipe length with two 90 degree turns then it will dump with the cutout open. Probably will dump it in front of the driver wheel.
