I have a 99 gst w/ 88k mies on it. I want to know how I can make the stock turbo last longer. Like what would I do to keep it in top shape. How long should I let it cool down on avg. what type of oil is the best for it and how often should I change it? Also are there any upgrades that I an do besides buy a new turbo to extend the life.

depends on your driving but around 90 seconds is good for a cool down after a typical drive. after racing or hard driving let it run a little longer. as for oil as long as your turbo is allowed to cool down it doesnt really matter what oil you use, but a thinner oil is probably better and it will give you better performance you will just burn it off faster and be adding a quart every so often.

so If my oil is slowly disapearing it's not a leak just the turbo burning it up?

A lot of people may use a thicker grade like like 20w-50 so they arent constantly adding oil. Thicker oil may also be a little more protective. If you use something lighter like 5w-30 your oil will burn off faster and you will have to add a quart evbery so often, but a thin synthetic is going to give you better performance because the internals are not going to be fighting against as much friction. If your adding a quart every week or 2 then you have a problem, but adding a quart in between oil changes is probably common

I've been told by my service that the best motor oil for high performance turbo cars is Motul 300v Le Mans racing 20w/60 oil. Im using it in my EVO 6 and so far so good. The thicker the oil the higher temperature it can withstand without burning, but watch out for warming up at every start. If you really car for your turbo you should start your engine and let it run on idle for 5 mins. By that time the water should be all up to the normal level, but the oil just passes the 40 C degree mark. After this you can cruise out off your garage but never push full gas nor rev higher then 3500 rpm util the next 5 miles. After this start using the turbo (by pushing the gas a bit harder) and make another 2-3 miles. Then there you go push is as much as you can. Once finished racing, never turn off your engine. The turbo temerature depends on the rev. range you'been using your engine. Long high speed highway rides heat up the turbo the most. It is common to see 600-800 C degrees and it is bright yellow

So the best way is to slow down 2 miles before destination, let the engine rev around 2k. Once arrival let the engine go on idle for another 2 mins. This way its gonna last forever.

id use ONLY senthetic oil blend(in my opinion), and after a normal drive id leave it on for like a minute or two. after a hard drive(which im sure you do to you car

id let it cool down for 5 minutes or more.
