Have you done no research on the turbo that your truck has currently? The he351 is much much bigger than the hx35 and superior to the hx40 as well. A he351 can support a very warm 500 hp run.

Unless you are producing over 550 hp, replace it with another he351. You can usually find these for 300-400 dollars in the classifieds or Craigslist.

Well with the injectors and smarty, you would be alright with the he351, but a 62mm could help cool things down if you want to upgrade to a bigger turbo.

Well it will be a little laggier down low but will flow more air and have more boost up top once spooled as well as lower egts.
