Default please help! durable turbos?

I am at the hardest part of my build so far. I have :
fully built 2.0 closed bottom end
bc 272? cams
bc valve springs
sti shim less buckets
ferarra? inconel exhaust valves

aps fuel system
750cc injectors
and plenty i have forgotten along the way ha ha.

I will most likely go with an autronic ecu so that i can use the anti lag function and switch it on and off as well. (I'm going for a higher horse power tarmac rally style build).
i do not need a lecture on how hard it is on any part of the car to run anti lag, I'm well aware. what i do need is a few recommendations for turbos that can make about 400 whp, twin scroll, b.b. and of coarse as durable as possible.
any help would be greatly appreciated!

The limiting factor is the twin-scroll you seek. There are only a handful of aftermarket twin-scroll turbos that make 400+whp - and I don't how durable any of those are over standard single-scroll turbos or if there is any bonus apart from more efficient spool.

If you want durability, perhaps look at what the rally and/or race guys are using - from memory it is the material used in the turbo that make them durable - and from memory it is a combination of magnesium, titanium and inconel turbo parts that keep them alive. This equals huge expense.

To keep costs down, you might be better off buying a turbo that is cheap to rebuild and uses an inconel turbine wheel that can withstand the extreme heats and violence associated with anti-lag.

Maybe a custom 60 series turbo from Turbonetics, with T4 divided housing and their F1 turbine wheel would suit? And being F1, you'd expect it to withstand anti-lag

I dont understand why you want to run a twinscroll housing on antilag? I mean with antilag it should spool almost no time! Anti-lag kills turbos why dont buy a cheaper less effienct turbo that you can just replace for a couple houndred. I mean no turbo will stand to antilag. but turbonetics would be way to go.

well what are some ideas for the 400whp range that are rebuild able and more cost affective?
