So I took a chance and installed tomioka racing 15t turbos just to see if they were any good. I put 7k miles on them at 24psi and they made really good power. 21 psi showed 525whp. Anyways while doing some half mile practice pulls at 160mph i blew the turbine shaft I'm guessing. Tons of smoke and no boost. Afr on bank 2 is pig rich from being oil soaked I'm guessing.
Anyhow now I'm in the market for some real turbos. I've narrowed it down to RB twins or mmp stage 3's. I have looked and really cant find much on the reliability of either and what would be best for around 650whp. That being said if anyone has any experience with any please chime in. I'm no opposed to single turbo, I just like the sleeper look of stock twins.
Also I'm a tech at a bmw dealership so doing a turbo swap isnt the end of the world and I have access to all the special tools. I just want something that I dont have to mess with ever 10k miles.
