I will have to look into those options as long as they can meet my criteria.I want full boost around 4000 rpm, would like to stay bottom mount, I would also like to be around 350-400 whp at about 19psi, keeping the T25 flange is a must for me due to ease of keeping things simple.With that being said the Gt series turbo's are pretty much everything I am looking for... I know my bottom end is going to be solid, but it is a platform that I built to handle much more power then I would ever really put at it. This car will probably never be anything more then a street car. It will deffinetally never see any drifting events except from the parking lot. It's main purpose is weekend cruising...... A hx40, isn't that used on cummins diesel engines? The link here doesn't show effieciency past 300 hp ....

My top end and turbo upgrade won't be untill at least the end of next summer, so I have some time to make up my mind. I want to be able to drive this car as much as possible next year before I have to send the cpu for it's initial tune at enthalpy or JWT.
