Dude, the thing about the 2.3 turbos is the turbo part of it. That means that you're jamming more air into the engine that would usually fit.
A bit of math and physics to think about.
Normal atmosphere is at about 14 psi at sea level. We don't feel it because it's all around us. Just a fact.
So, running no boost, your 5.0 is jamming 5 liters of air into the engine per cycle. Our 2.3 is jamming 2.3 liters. That's obvious.
The SVO and TC came with a stock turbo that ran at about 14 or 15 psi. That's an <i>additional</i> 14 psi over normal atmosphere, or twice atmospheric pressure. So essentially, stock 2.3 turbo motors equaled a stock 4.6 v8 motor in displacement.
You do the math and you can figure that it takes about 16psi boost to jam as much air into our 2.3 as you can into your 5.0.
But the thing is, the 2.3T motors could handle a hell of a lot more. Often you see 2.3T's boosted to 25psi. That ends up equaling 6.4 liters of effective displacement. I've even heard of these motors being boosted as high as 30psi (effective displacement of 7.2 liters) with stock long blocks!
And anyone can tell you that SVO's and TurboCoupes didn't come from the factory at 10 seconds. Stock motor means just that. Stock <i>motor</i>. The long block is exactly as ford made it. The intake, exhaust and turbo have been modified to handle the high boost, but not the engine itself.
So stop knocking the 2.3 turbos, because we basically have the ability to jam a 427 under our hood, but get the mpg and weight of a four banger. (Oh, and my 2.3 gets 33mpg, 25 city, the only mod being a K&N filter)
