This was posted in the wrong section and as such was buried in the moderation queue. I've moved it to the correct forum. If you still need help with it you should fare better now.

Let's start from the beginning, ok?
  1. What is your model year?
  2. Was it originally a TT?
  3. Please list all modifications.
  4. What have you done so far to troubleshoot.
Obviously, your mechanic isn't competent to diagnose a problem with the Mkiv's full sequential twin turbocharging system. Are you willing to learn what it takes to do that troubleshooting yourself? Be forewarned: it's a somewhat complex/intricate system. Here's what you can read, just to begin to scratch the surface of what you'll need to understand:

http://mkiv.com/93-98-twin-turbo-faqs-2/#apu1

If you don't have the time to pick all this up yourself, let us know and we'll try to locate a properly experienced and equipped mechanic for you to go see in your area (yes, we can even help you find someone in north Ireland!).

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
