Prodigy has several customers in the middle east already, so they may already have some feedback and recommendations for hot climates. I believe they offer a water-cooled ball bearing Garrett turbo option primarily for hotter climates. Maybe Prodigy can help you contact some customers or install shops in the middle east that already have experience with their turbo kit so you can get some ideas of what is necessary/helpful.
* Turbo blanket for sure. I consider that a recommendation for everyone, even in mild/cold climates.
* Ceramic coating on the pipes should help with under-hood temps and intake air temps, which will help the engine run cooler. How much will this help? I have no idea. The pipes between the engine and the turbo will be the hottest, so those would be highest priority for coating. Keeping the heat inside the pipes can also help the turbo run more efficiently . The downpipe may be worth coating also, but will have a smaller impact on under-hood temps than the pipes before the turbo.
* The stock catalytic converters are removed when installing the turbo (one on each side of the engine, tucked up in the engine compartment), and the turbo exhaust system includes a high-flow catalytic converter that is below the front seat on the left side. That's two sources of heat removed already
* I've seen mixed opinions on a 180* thermostat. If you don't adjust the calibration of the radiator fans to come on at lower temps to match the thermostat, then you only cause the engine to heat up more slowly, but the computer/fans will still try to keep the temperature in the low 200* range. If the computer is recalibrated to match the thermostat, then you may be running the engine at a lower temperature than it was designed for (reduced efficiency, more pollution, etc). I would talk to Prodigy about this and find out what their other middle-east customers have done.
* Vented hood seems like an easy way to help keep the under hood temps lower. I like what I've read about the Daystar Hood Cowl and Side Vents. They are actually designed and tested to flow hot air out even at low speeds. Some vented hood designs depend on airflow over the hood to draw the heat out. Check out posts #8 and #11 in this thread: http://www.jkowners.com/forum/showth...50#post2773050. I'm slightly concerned about rain getting in the side vent, because it's somewhat close to the air filter. I would probably use a water repellant air filter wrap (Outerwears, for example) to protect the air filter from water dripping/splashing through the hood vent. But maybe it doesn't rain often enough in Dubai for this to be a concern for you
* The turbo does not seem not produce much excess heat when driving "normal". It only spools up and produces a lot of heat when the engine is under heavy load. For daily driving, I think concerns about under-hood heat from the turbo are exaggerated. But it might be a valid concern in 120*F heat. Again, I think Prodigy may be your best source of info about this because they have sold several kits in hot climates already.
