Help me select a T3 turbo with an internal wastegate (400hp in mind

Im looking for ideas on selecting a new turbo that has a t3 footprint and an internal wastegate. I currently have a Begi t3 manifold with a holset hx30. Performance is great but I'm looking for more power. I've started looking around for a different set up. But I haven't really found anything solid yet.
Anyone have any ideas for a 400hp set up that's internally gated?
My set up is a 95 forged bottom end with a 99 stock port head.
I don't want to run more than 20psi and would prefer pump gas and maybe meth injection.

Maybe an 18G?

18G can definitely do it, but it will be tricky. You can get an internal gate 20G and that can make 400HP pretty efficiently.
I would also consider something like an S300 series BW. You can get some interesting tubrine housings there with internal gates from places like Bullseye.
Why is internal gate such a big deal? After yers of boost creep lameness on my old DSM I just did a super ghetto EWG setu on a stock mani and never looked back.

people were giving me **** for wanting internal for my 300whp setup.
I went iwg anyway. it DOES creep a little bit, like 1-2psi in 4th/5th between 5500-6000.
I actually like it a lot, its quiet and still gets the job done.
now,
at 400 I don't know how badly the creep and boost instability might be, so I'd be really nervous about running iwg.
maybe if you go with one of the new bw efr turbo's that has a really nice iwg setup, but on a regular turbo I'm afraid it would be creep city for you.

I must say though, I ported my wg opening a LOT. Had I not done that I'm almost certain I'd be seeing a ton of creep.
The new bw efr turbos seem to be doing just fine iwg, and I think it has to do most with the way theirs is designed. So at least now we know that you CAN have good control and flow through an iwg turbo, just depends on how its designed.
I truly hope other manufacturers see this and we start seeing more well designed iwg turbos.
EWG routed back into exhaust stream negates the power gains and vta just isn't for everyone (that doesn't want to wake the universe when they go WOT)

Some hx 35s & 40s have internals and some do not. Still haven't really decided on a turbo so far, I've started researching more on holsets again. My hx30 compressor wheel now has a 44mm ind. And a 73mm exd. I have found after market hx35 compressor wheels that measure 46mm ind. And 83mm exd. I'm going to see if the compressor housing can be machined to accept this larger compressor. I have yet to see anyone accomplish this yet, maybe it has never been attempted.
Do to clearance issues with my manifold/turbo combo I can not step up to a hx35.

Just give it a few days and more should show up on cummins forums.
Also be on the look out for variants like the HY/HY 35/40 hybrids. There are a bunch of different, usuable turbos that come up.
Those are all a step up from the HX30 and will net you 400hp.

We are, amongst other things, a Cummins engine dealer where I work. We end up with blown/damaged turbos somewhat frequently. The HX40 is typically not found on the B-Series (5.9 liter) engines that come in Dodge pickups. It is more likely to be found on the 8.3 or 8.8 liter engines found in larger trucks and machinery.
