Saturn 2.0l Supercharged - Sooweeeet maaate!

[blackSRi]

How would it get much heavier? surely we aren't talking about many kilos...?
The SAABs don't change much between configs - I found the figures before, but I don't have them handy.

I'll do a Z22SE over a cast-iron block 2.0L (Z20SE?).
What's the weight diff between these two? anyone know?
What I would love to see is the Alu Z22SE turbo'ed - but 125kW is pretty impressive over 107-108kW normally.

Yeah i guess the change would be that great.
I just cant see the point of a 2.4 that produces only 125kw.

[blackSRi]

You mean nearly 20% more ouput normally aspirated isn't impressive to you?

Hang on hang on how much does the 2.2 produce?

[blackSRi]

108kW on PULP

(more kW on 98RON, derestricted airbox, chip, exhaust 2.25" straight through etc).

So 16% min improvement or 18% min improvement over the yank Saturn VUE figures.

GM Powertrain Debuts New Engines at SEMA
Andrew Charles
AutoReport

GM Powertrain is using the 2003 SEMA trade show in Las Vegas to show off three new engines, including two engines with Displacement on Demand (DOD) cylinder-deactivation technology for improved fuel economy. GM expects two million vehicles with DOD-equipped V-8 and V-6 engines will be on the road by 2008. GM Powertrain is also showcasing a new Ecotec 2.4-liter engine, which brings both larger displacement and variable valve timing to the Ecotec modular family.


General MotorsFor the new LE5 2.4-liter both cylinder bore and stroke are increased in relation to the original Ecotec 2.2-liter engine. The new engine's bore is 88 mm and stroke is 98 mm, versus the 2.2-liter's 86 mm bore and 94.6 mm stroke, yielding a total displacement of 2,384 cc versus the original 2.2-liter's 2,189 cc. Developed to enhance the low- and midrange torque output of the new engine, the new variable valve timing system uses electronically controlled hydraulic camshaft phasers to alter the relationship of the intake and exhaust camshafts as much as 50 degrees relative to the crankshaft.
"We have added technology to improve low-end torque and continue to reduce emissions. For the new Ecotec, variable valve timing helps deliver 90% of the torque peak at as low as 2400 rpm. That sort of responsiveness enormously enhances engine response."
Jay Subhedar, Ecotec global four-cylinder engine assistant chief engineer.
The Ecotec 2.4-liter, with 170 horsepower and 170 lb.-ft. of torque, will debut on the all-new 2005 Chevrolet Cobalt. The Cobalt will also be available with the latest version of the Ecotec 2.2-liter, expected to produce better than 140 hp at 5600 rpm and 150 lb-ft of torque at 4000 rpm.

Here's a picture:

The 2.4L would be too heavy for the Astra, and with it only producing 125kw, its pointless.

Basically Paula
What ya said is Like having a 302 Cleveland in a Fairmont then changing it to 351. Its only Crank and Rods and the Weight is the same.

LOL... the all alloy 2,2L SRI is lighter than the turbo unit in the SRI Turbo.
The 2.4L would be little if any heavier than the 2.2L unit.

From the specs the SRI is 50kg lighter than the SRi Turbo. A fair whack of that must be the engine.

My appologies Glenda

Yeah well now that i see figures, i can see the point.
Appologies to all.
