The last long trip I took with this car, to Indianapolis and back. I averaged 40 mpg ( 3.78 L us gallon). Combined city hwy is usually around 30 mpg. My gas guage does not work so I am always figuring out mileage. I use my trip odometer to decide when to fill up.
Yes it is the f23 that came with my first 2.2. From a 2004 cavalier. It still has the original clutch too. When I built up the newer engine, I ordered in a new clutch. When I compared it to the old clutch, I sent the new one back because the old one had no visible wear. At that point it had 80,000 KM on it. I like GM oem clutches.
I wish I had your motor. My car has a 3800 SC engine with some mods. It is fast, lots of torque, but I worry about blowing up the Getrag and it runs out of breath at around 5500 RPM. Your car sounds more like a traditional "sports car" and the tranny that came with it can put up with pretty much unlimited abuse. Plus the Ecotec has lots of aftermarket support to really bump up the power.
I think a 300-350 HP Ecotec would be an amazing engine swap for a Fiero. Fast, reliable, good on fuel, and fewer worries about blowing up axles or transmissions. I hope we meet one day and go for a spin!
Thanks for all the comments. When I decided to go ecotec what I really liked was the way they rev. I have mine set to rev to 7000 and pulls strong right to the rev limiter. I could push it a bit higher but around 7400 or so is above what is reccomended for the stock valve springs. I don't know what kind of power it puts out, it has never been on a dyno. For my purposes it is fast enough so I am not too worried about getting more power out of it.

From the driver's perspective, assuming the same hp, what's the difference between a high-RPM engine with short gearing, versus a low-RPM engine with long gearing?
I guess I'm wondering what's the fixation with the redline number on the tach... the number doesn't seem so important to me. I read that tachometers on airliners read in % of redline.

I guess there is no easy answer to that question. But an engine that pulls strong to a 7000 Rpm redline is much more entertaining than one that dies at 5600 rpm. I can do 100 mph in 3rd gear. When I am on the road course in Grand Bend, I leave it in 3rd and drive the whole course.

If being able to hit high speeds without having to shift up is nice, the Fiero MY8 transmission would allow cam-a-lot's car to hit 100 mph in 3rd gear at 5500 RPM.
and the lower revs should have enough torque to leave it in 3rd all the way around the track. So it should behave similar, but you don't get the aural stimulation.
