Well, my turbo stopped spinning.. need some input, Intercooler = cause? Options

[mark_426]

Intro: Well, I took my car to celicagurl152003 and had quite a bit of expense put into it.

Throughout the work to my car, the intercooler "could not be installed" and I was told the car would be "fine, if not better" without it, due to the length of the piping. Ok, so I drive it home, seemed to run fine, minus something occasionally that seemed like a backfire if I punched it and tried to run the rev's up in the current gear.

Regardless, I was doing some electrical work this past weeked (7-10th), and I finished some of the electrical up, and got the battery charged, and went for a drive. THis is when I first noticed no boost. After it cooled and such, looked at it a bit, and asked some opinions of some of the alltrac people locally, didnt really get anywhere. Anyway, I had to change oil, and some other stuff under the hood, and finished that up, pulled it out my driveway, turned around, still no boost.

So, the real question: Anyway, my turbo currently will work about 10* back and forth from its current location, and then it feels like it hits an obstruction. It turns freely for the few degrees it does turn, but will turn no further.

What would cause this? Is it easily fixable? Would it be related to having no intercooler?


Heres a pic of the engine bay as it was until the turbo stopped functioning:

This is true but not really informative. Its one of the only turbo cars without a stock bypass valve (which serves the same purpose as a blow off valve). If you plan to run more than 7psi, you will significantly compromise the longevity of your turbo without a BOV or bypass valve.
