Thanks @Yaser!

The SHO's arent really a good platform to use for building a performance machine. They are EcoBoost powered and those engines really don't like being pushed.

In addition, the water pumps are famous for going out and taking the engine with them. Plenty of information online regarding that issue as it is widely acknowledged.

I wouldn't mess with the boost on those cars. If it isn't quick enough as it sits for you, I'd look elsewhere for a fun toy to build.

@Mod_Man is a great source to answer your question. Thanks in advance @Mod_Man. 

I would not put bigger turbos on it will actually make them wear out faster

Not a good idea.

I would avoid it.  See my post below about the water pump issue:  also that has the 3.5L Ecoboost V6 (and 2010 was the first model year on the Taurus that it was offered) which can wear out and that one is already at 135,000 miles.

I really enjoy my 2016 SHO. It is very sporty for a 4 door 4300lb car, but it is no mustang or corvette. With 68K miles on it, the main things i would be worried about would be the turbos and water pump. The waterpump is an internal waterpump and is driven by the timing chain. So replacing it is not too difficult but is rather labor intensive. The turbos can also be labor intensive as well. The PTU is warmer climates can be an issue. They often overheat and fail, leaving you stranded. I change the oil in it every time I change the engine oil. The transmission is a good transmission, but the filter is not easily changed and I change 5 quarts of ATF every oil change as well.

If it has the PP package there has been a recall on a part of the rear suspension (one of the control arms if I remember correctly).

I none of that bothers you (like me) it is a very fun car and does great in the winter.

I got a 2014 Taurus SHO with 101K mi from my friend mechanic. He sold it to me for $8500.The car is in a really good shape, paint is like new, brakes, oils.

I know about the PTU and water pump issues, the question that I have is:

Would it be a good idea to buy bigger turbos for this car, but tune them to make the same power as it did (365-370hp), basically making the turbos do less work. Would that help with the longevity?

Scotty, I'm looking at buying a 2010 taurus sho with 135,000 miles is there anything to look out for before I buy it?

Get it inspected. Make sure that all the warning light come on when you first turn on the car. If the dont, that could mean the owner unplugged them prior to your visit. Check to see if it has been it a wreck by measuring the amount of space between the tire and the body. If its 6 inches in the front and like 7 inches in the back, the body is bent and the car might have been in a wreck. Look under the hood for paint overspray. If there is that means the car has been repainted for some reason. Look under the steering column and see if its rusty. if it is rusty water has been there and the car might have been flooded. Check under the floormats too. if its all moldy and it smells like mold then that part may have been under water too, and be real leery to about any heavy perfuming. The owner might be trying to hide the mildew smell. If the owner has an OBD2 sensor (scan tool) and he shows you the codes and nothing is wrong there, he might have erased the code prior to that. So drive the car around for about an hour or so and hook up the tool. If it trips any code do some reseach to find out what it means. And like BruceRee said, always have it inpected prior to purchase. Hope that helps

As @Daywalker said, avoid it. That water pump issue is no joke.

Scotty, I want to buy a weekend car and looking into this Taurus SHO with 20K miles. I'm planning to heavily upgrade the vehicle with performance parts, but is it a worthy platform?
