Why should I consider a 2L turbo over a V6 engine? A) Fuel savings? B)Engine last longer? C)Less Maintenance? D) NA engine have a proven track record? E) … the $cash savings for the Manuf.?

The choice depends on what you find important, how you plan to use the vehicle, and how long you plan to keep it. I’ll expand on that later when I’m in front of a computer with a full keyboard.

No personal experience, but one thing for certain, you’ll never have a turbo unit or inter-cooler fail with the 6 banger non-turbo.

You shouldn’t consider the small turbocharged engine. Those models only exist to improve the manufacturer’s CAFE ratings, and to be able to advertise a higher fuel economy figure. There’s no real benefit to you, the owner, versus a larger normally aspirated engine. This is very similar to the bas…

No longer a choice on most all cars/CUVs/SUVs. Turbo 4s are often the only engine available. And it’s no ‘ruse’, it’s the future. Everyone from Alfa to VW.

One major plus for turbo 4’s versus NA 6’s is that there is typically more room to service them in the engine compartment AND you never have to fight with spark plugs wedged against the firewall. I have always bought NA 4’s and just bought my first turbo 4 in my new 2018 Mazda 6. The turbo in the …

Owned 3 turbo 4’s starting in 1985 until now. Never had an intercooler, intake hose or turbo failure. Combined mileage on the first 2 was 195K, years owned 30 total (17 plus 13), the 3rd was bought used and now has 32K on it with no problems. The last 2 had essentially no turbo lag and got over 30 …

friend has an infiniti g37 w/300hp v6. he rented a new model that has a turbo 3.0 that makes 300 hp and he liked it. seems there is a 400 hp model that is also 3.0 but has a different turbo setup and liquid intercooler setup and about 100 other tweaks to make the extra 100hp. maybe the base turbo mo…

OP, if you live or frequently drive to high altitude locations the turbo will perform better than NA. Turbo/supercharging was a game changer for piston engine aircraft.

A V-6 is going to have lower RPM torque/hp. This is real useful for towing or hauling. The turbo doesn’t kick in until higher RPM, so not a good choice for towing. Depending on the engine and the turbo setup the V6 might be easier to work on because of a lot less plumbing.

Mike, that used to be the case, but modern turbo engines are often tuned for lots of low end torque.

Except my turbo 4 Mazda 6 makes 310 lb-ft of torque at only 2,000 rpm. The engine was made for the Mazda CX-9, an SUV built for towing. It’s all about how the turbo is set up and tuned.
