FSI engine for everyone! What ford is basically selling is what Volkswagen/Audi had been selling. Just take a look at the Golf Turbo charged engine fuel consumption, it is lower than the N/A engine.

If u want to safe fuel wif Turbo, low pressure turbo are great to run. I own a Turbo Kancil L502 and i know the difference between my old L200 caburated engine.

4G63T, if u dont care about the performance and care about F.C. U can try modifying the turbo into smaller DT03 or Subaru twin scroll turbo and higher compression piston, from 8:1 to 9:0 for better pick-up. But the hp will drop almost the just 180-200hp. Subaru turbo might be higher a bit in hp.

Turbo all the way!

As on my 4G63T, On cruising, it jsut works as a regular N/A engine, perhaps slightly worst due to the lower static compression ratio, as a slightly detuned 2.0L engine. However, stomp on the loud pedal and you get the power equivalent of a highly tuned 4.0L engine.

Obviously, if it has the power of a 4.0L engine, it will drink gas like one.

But if you can resist the temptation to boost all day long, a turbo car can be pretty nice on gas. On cruising with some boosting on overtaking, its not uncommon to see well over 500kms per tank of 43L. Bear in mind, my car does have a power sapping AWD drivetrain. So factor in another 15-20% better mileage on a regular FWD car.

Due to the design of a N/A engine, it will never meet the volumetric efficiency of a force fed engine. In the last few years, turbocharging and engine technology has improved (no doubt by the popularity of turbo diesel cars) to make another comeback.

Turbo engines are great for countries such as ours where road tax on large CC cars can be prohibitive.
