It was 1998 and my friend Tom had just picked up a 1991 Eagle Talon TSI AWD.

“Ok, go ahead and floor it, but don’t rev it past 5,000 rpm,” Tom said.

I mashed the throttle and … nothing happened.

We were moving, but it was at the pace of a Toyota Corolla and nowhere near the rate of acceleration promised by the 2.0-liter turbo’s claimed 195 horsepower.

Disappointed, I left my foot on the throttle for a few seconds. Suddenly, I heard the whistle of the spooling turbo and a sudden shove of boost kicked in.

Four-cylinder turbo engines from the ‘90s were all similar to this. While they generated relatively big power at the top end, they also suffered from massive turbo lag and had fuel economy similar to a much larger V8.

Nissan’s new Variable Compression Turbo engine promises big power, minimal turbo lag, and decent fuel economy using some new trickery.

Is this the holy grail of turbocharged motors?

Hi Sajeev, I have to find a new mechanic – my former mechanic is permanently disabled (bad shoulder – he can’t even hold a gallon jug of milk with his right arm) and his old shop is just not responsive – or as competent as I demand. So, with great heartburn, I have to find a new shop for those repairs I am either unable or unwilling to perform myself: which is most since I do not have a garage or even a driveway, much less a lift or even jack stands as the street in front of our house is pretty well sloped.

The cars in question are my resto-mod 3.0L Contour SVT, my wife’s Camry and probably my mother in law’s Millenia S (with the weird miller cycle engine). I can tackle basic repairs with my car, but sometimes it’s just easier to have someone else do it.

How should one go about finding a new mechanic / shop? What questions do you ask to determine competence? I proved a long time ago that I knew more than my local Ford dealers (including causing service advisers to get fired due to my complaining about their ignorance – including yelling at one standing underneath my car on a lift arguing about the rear sway bars), but I am not opposed to company shops if I know the mechanics are competent and the rates reasonable.
