Engine Swap!! Which engine though?

So im planing on starting a pretty big project on my 2004 Saab 9-3. However im about to hit 150k miles which im pretty concerned about, because of the money ill need to dump into the car to complete my project... So anyways this forum was just created to see what kind of engines i might be able to use to do a successful engine swap in my 9-3, or to see if i could even do a engine swap in this unique car.

The engine i am most interested in was the Neo 6 2.5liter turbo from 2000 nissan R34, or some kinda engine that is AWD. Just a reminder im looking for an engine that will give me more BHP then my regular 2004 saab engine. Im open to any ideas as im anxious to get this project under way. Any information is appreciated.

Thank you!

Why not just rebuild your existing engine for more power? A swap would require a lot of serious fabrication.

You have a GM Ecotec engine, and the power outputs and parts needed are extremely well documented. Search for the GM Ecotec Build Book and hang out on the Cobalt forums...

I don't get it. Agree with Mike, it's a well built & proven engine. I'm not sure what you gain by departing...

im more worried about the miles. If an engine goes... it goes right? or would rebuilding the engine prevent this?

Rebuilding would "prevent" this, since you could get Forged JE Pistons (genuinesaab.com), new bearings, etc, etc... Doing an engine swap with an engine from another car would require serious fabrication and you would never see your ROI in my opinion.

The Ecotec motors in those cars are excellent. My wife's '04 had 193k miles on it when we traded it in, and the engine was still as strong as the day we bought it.

Just remember, these are similar to the motors in the Cobalt SS, only better!

Rebuild the motors, throw a buncha boost at it. You'll have some fun without wasting money.

All of this, x10.

You'd be MUCH better off with a rebuild, and you'll be able to find the parts fairly easily. The GM Ecotecs have been taken to over 1,000 hp by testing the engines to failure, analyzing the broken parts, and then substituting stronger components until others fail...then repeating the process.

An engine swap just invites problems unless you have years of fabrication experience under your belt.
