I asked my instructor at auto-tech once about why we needed a 6 liter turbo-diesel V8 that only does 350hp and 400ft-lbs of torque when a 4g63 2 liter 4cylinder can make those levels of power.

His reply was: The v8 will last 200,000 miles of heavy duty use. The 4 cylinder will not last that long while being stressed to the same point.

The 2 liter 1000hp formula 1 engines of the 80's were powerful, however they only lasted for a very short time, I believe they had 2 engines just for qualifying.

I think that a stock port 20b with a mild single turbo and low boost will last a lot longer than a high strung 13B with the same power output. also, the natural torque off boost makes it more drivable from what I have read so far.
