Single or twin turbo

Nice. I also know that Hellion has made a good name for themselves. I am selling a turbod acura that I have now to pay for the motor and turbo kit. Everyone has a boosted honda and its getting old. Id much rather say I have a boosted mustang than a honda even if my acura was faster. Is the 62mm turbo that comes with the kit decent to make over 500 on a stock 96 to 98 cobra motor in stock form?
 
I'm not familiar with their kits but if they are low mount you'll need a scavenger pump. With twins you also are looking at more crap that can fail. My turning radius is also smaller as my tires rub the piping if I turn the tires all the way.
