2.0 EcoTec in a GBody?

Kinda of like a GoCart on steroids....

I think the EcoTech turbo is a great idea.

I was also thinking that one of the 3.6VVT V6 engines (CTS/Camaro/G8) with the 5 speed auto would be sweet in a G body.

I drove my friends Caddy CTS with the V-6 and 5 speed stick. LOADS of power and a dream to work through the gears. I think that would fit our cars without much trouble.

I saw some where, that they were using the engine mounts out of a 4cyl canyon to do a nova?? They also had an adapter plate for a 700r4. Not too shabby 8) . I think a EcoTec swap would be really different, and it would make a good autocross car.

That is impressive power, especially torque wise at 2400 rpm. The 3.6 would be just as cool, especially with a turbo. I am super or turbo charging my v6 Challenger after the warranty is up. Adds 140 rwhp to the 3.5 plus 100 ft/lbs of torque with 10 lbs of boost.

295 TQ at 2,400 is ok but if you don't have great torque you can make up for it with gearing which the new 6 speed should do well. With an old 3 speed like many of these cars came with it wouldn't be a lightning bolt. My car with me in it weighed 3,840 on the scale. Fuel economy and engine longevity comes when off boost. The 4 cylinder needs boost to move the car moderately. A turbo V6 would be a better choice in that it naturally makes more torque and lower in the rpm range on & off boost. It would easily move the car moderately or easily with normal traffic again off boost which in fact my turbo 3.8 V6 does.

2.0 I4 ecoboost
270 HP @ 5,300
295 TQ @ 2,400

3.5 V6 ecoboost
365 HP @ 5,000
420 TQ @ 2,500

Factory GN 3.8 V6 turbo
245 HP
355 TQ

The question to me is the torque at 1000-1500 for a full street car. For a performance build with a stall converter, yeah 2400rpm is fine.

It will still be better than what the majority of these cars originally came with. Nobody even measures power output at that low of an rpm range but with a torque peak at 2400 it will have enough power even lower.

The big thing is the power curve, big engines have a wide curve while small engines have narrow (peaky) curves. Big cars like G bodies need a wide power curve for street driving, a narrow band may be okay for racing but not for normal driving where the engine usually runs at low RPMs most of the time. With turbo engines boost kicks in at higher RPMs where the engine needs it.

I've never understood the "HP per liter" comments?

Sure, this engine might be 135HP per liter but why does that make it better than say a 455 making 550HP?

The 455 would only have a 73HP/liter but would still kick the crap out of the 135HP/liter engine....

Those MPG numbers don't look all that great either considering the guys with Corvette's and F-body's can manage close to 30mpg on the highway.

I'd leave the 4 banger for the small cars and keep the big stuff for the G-body's.
