80mm is about as big as you want to go on a stocker
need at min a 68mm
iirc a S510 has a 90-10Xmm inducer
now get a good deal and you could shelve it till you had everythign else

Cant wait to see what my s475 over the stocker does then Im gonna put 40% overs in it and see how much it improves. I hope to run low 12s but idk.
Torque converter setup might hurt/help in many case. It is very important to choose a good converter for your setup.
When i baby around town, it is a bit sluggish with cold temp but i dont have any issue spooling it and it is pretty fast to spool when WOT. My ET also represent how badass the 475/stocker can be at the track.

I have a ml converter Its good for a stock turbo but idk about stocker with a s475. When I built the trans I said this one will work I wont change the turbo set up anyway. But I also said I would leave the truck stock when I bought it. I guess I lie to myself alot haha.
I had a ML converter in for the runs in my Sig. It worked really well for me. At times I wish i had it back
if i put an allison in the truck...the convertor will be tighter then the 1056
in the 1500-1700rpm range..
what ever stall that came stock with the 6.5TD works amazingly well behind the dmax especailly in the heaving towing area..

My batmo and race covered S475 over stock spools quick and is plenty snappy, except from a stop to about 10mph. Obviously not an issue with a boosted launch though. Also, I definitely drive it differently because it is smokey as hell below 1600ish rpm. Don't wanna get busted since I just moved to Cali and the CARB is rough with fines.
I'd have gone with a tighter converter, especially since I'm back to stockish height.

you put 37s under that truck and tell me if you can light the charger at 55mph without kickin down a gear
:rofl:
I was not aware of that. I do plan on twining the truck in a few months once winter is done for out here. Im only 45 min away from duramax tuner. That's who Im gonna have tune my truck.. What size lift and tires were on the truck that the rods bent on?? What was the HP and TQ?
whoa larry haven't seen a post from you in awhile. Hope everything its going good.
This is the same way I felt about my twins and this was part of the reason why I went back to a single turbo. Absolutely love the way my truck drives on the street as a big single VGT. That being said I am going to re-twin my truck this spring for racing becuase of the power and egt's will racing with twins. I'm looking for 1K Hp single pumped with the twins...:spit:
i was and still am running 37s on a 8" lift and ran a track proven 550hp. couldnt tell you torque as it was never on a dyno but i know it was more than the rods could take. this was all on a 2900pw tune with falling rail pressure so i thought i was well under in hp for hurting the motor..........i thought wrong.
Ive run a few different setups over the years. My first kit was an 475/stock charger. I loved that setup for every reason already touched on in this thread. It spooled prety quick, hit pretty hard, and didnt really sacrafice much. It was enough to hurt the motor pretty sure too. James and I are a testemant to that. Before the rods decided they had enough, I swapped to a 'race' tripple setup from EPR and swaped to a batmo wheel. I have no idea what the batmo did for the setup but I fiduged I was in there so mine as well. The triples spooled a little faster then the S475 by my seat of the pants. It also hit a lot harder too but kept EGT's even more in check. I had NO fuel on tap to drive them harder and I knew they were starved for more fuel. I had a few thousand miles on the setup before the motor had enough. it was a combination of both the twins, and triples and my heavy right foot. There is no doubt that the setup, kept conservative, is a nasty street set up. Im sure the same 'race' kit with a stock VGT (not sure if Trent has this out there) would be the tits as well.
Now that Im not in the stock motor club anymore, and I can comment what 100 overs and dual fuelers feel like, holy FAWK it is a whole different ball game. Not much seat time on the setup, but I was impressed with the street driving maners. It was docile, yet spooled wicked fast with little effort. I want to see how far the stock charger will let me take it, as I dont want to sacrafice spoolup as its downright fun! Im sure Ill have some lag like the bigger twin setups have. Ill have to get some vids up so everyone can see what im talking about. I wouldnt do it any differently

Good post by OP.
Happy with my 474/ stock setup! ( If I had the cash to build the motor.......well..... )
