Best turbo upgrade for 400-450 whp

[Norm1M]

My car is currently sitting at 78 000 km and I was looking at upgrading my stock turbo.
I'm not looking at making big power but something in the range of 450 whp would be great.

I'm doing 4-6 track day each summer so I'm looking for something reliable.

I have dinan oil cooler, Wagner evolution II comp FMIC and AFE Magnum force cold air intake.

I would like to know what would be the best suited for me ?

I think the RB ones are a good choice and the stock fuel system can support them up to 500hp at crank, 425hp at wheels. Should also not fall off power ~6k rpm like stock turbos, but hold boost to 7k rpm without pulling timing.
