Ecc had one of the best running non-intercooled 6.5's I've ever seen, but he spent big money on it.
Injectors, tuning, waste gate, maybe some pump mods, exhaust, intake, those plug inserts that give more fuel, that crazy cooler thing that keeps it from shutting down whenever, and a few other things.
It was about the same as a stock duramax power wise, which is really good for those things. When he sold it, it was going south fast.
I can't believe you hosed the turbo already, try ebay for a cheap replacement.
Disclaimer: don't think you can get big power out of that thing, leave it stock and save your money for the D-max.
