I had owned a heavily modified Supra before coming to Qatar. The very very few examples of modded cars I have seen here have been imported that way, after talking with the owners. That said, I wouldnt trust a single mechanic to work on that kind of car in Qatar. You just dont see anyone with that kind of experience here. I dont know of a single shop with a Dynojet or any setup for tuning a forced induction engine.

And to the guy who mentioned a list of turbo cars, those are factory turbo'd and pretty Zzzzzz... I am pretty sure the OP is talking about 500+HP aftermarket kitted, fuel system, cams, induction, bottom end, etc tuned cars. There are 2JZ-GTE engines out there running 1500+HP. That entire scene is, sadly, just completly nonexistant here in Qatar.

I had never heard of mods being illegal, but if true that would explain a lot.
