If there is a solution for mustang dynoed ~500whp (no meth) (~575 dynojet?) with a flat torque curve.

I'd be in. As long as the $$ isn't anything insane like 15 - 20k.

For much less $$ and still on stock turbo,

dynojet 420whp (with meth?) for a few grand? Is that too much to ask?

I would love an upgraded turbo once my stock one goes out, or once my warrenty is over.....just being realistic here. So I don't mind the wait. I just hope someone eventually makes one.

I would be open to it as well... I'm done. There is nothing more I can do at this point to the car.... still awaiting my final dyno but a pesky boost leak has delayed me.

Cool, are we talking brand new turbo or upgraded stock unit?

If we can get 400-420rwhp without meth and just 93 octane that'd be phenomenal.

Brand new turbo. This small turbo is pointless to work on.

How are you out of warranty for your n55? Did it get voided or you're past 50k miles?

new turbo is not 3k - its much less.... the problem is you would need a new manifold and other pieces to fit that turbo to our cars - running you a total of 10-15k... you could choose any turbo you want and buy it, just need a custom manifold built to fit to our cars

many people in the muscle world do this - I guess nobody has the balls or $$ to do it in the bimmer world, I will be the part with not being down to cough up enough $ 8)
