N/A Base Engine vs Turbo Engine

[Kirby]

Going through the Hot Rod Teardown Article Sept '03.

The article identifies that the head and block are essentially the same in the beginning, but:

Turbo Modifications:
Slight casting revisions for improved coolant flow,
An extra oil galley for squirting oil up into the piston (cooling),
Extra oil and coolant taps and passages for the turbo
Hardened nodular crank
Forged rods with added oil routs (to handle the torque)
Lightened, reshaped, and lower-compression eutectic pistons
Upgraded Intake and Exhaust valves
Upgraded head gasket
Cast aluminum valve cover with special internal baffles
Turbo intake and exhaust manifolds (quite obvious)
Intercooler (also obvious)

I might have missed some things, help me out here.
The question needs to be asked...if Chrysler wanted to make this engine cheaper for the 180 hp version. What pieces could they do without, and not run into long term dependability problems?[:I]

Hay Kirby . . .

Just a thought . . . but is it possible that DC did not try to save money on the engine and they accomplished the savings by eliminating the more costly GT options on the chassis?

Is it possible that they wanted to offer an engine that runs better on regular gas thus it was detuned?

Is it possible that the 180 engine is exactly the same engine as the GT?

[Kirby]

Exactly!

So what's the point?

We have a car with some extra features and more HP. I held off on the NA because of power, don't think a modest 15HP gain would have swung me over but 65HP?.... simply could not resist.

It's just a great car, versatility, mod ability, style and now power, to me, this thing has got to be the coolest vehicle to come out of any manufacturer in a long time. DC has a great line up right now.

Some hangers on feel that no matter what is said, the new 180 couldn't be the same engine as in the more expensive model. The point is that the internal things that "have to be done" to put a turbocharger on any 2.4, makes putting togeather another completely new 2.4 engine simply not worth it.

The "Value" model is just that, a great value!

Besides, some people don't know what the internal differences are, it might just be somewhat entertaining to find out what some of the pieces and parts are that make a turbo engine stronger than a normally aspirated engine.

The internals can be the same, they are probably using a different PCM, less boost, less octane, probably more restriction on the intake and exhaust side, before your know it 35 horsepower are gone.

And the good part is probably easily resurected to its former glory with just a few mods.

[Culprat]

This would be a good place for the stock pcm and injectors.
