I really dig the 2.2L Ecotec engine GM makes and all of the accessories/parts available for it. I'm wondering if anyone in the community has thought about throwing one of these into their Fiero. Any tips, suggestions, warnings, etc would be greatly appreciated!!! Please - I welcome all help and ideas.

there are some people "in progress/recently finished" with this swap, check in the archives to see if you can find them. I follow your excitement for this swap. It is definately my next swap.

I think fieroturbo is the only one currently working on an Ecotec swap, but it's a big forum and I could be wrong.

Looks like it has a huge amount of potential. Could replace the 3800 as the "common" swap, once some people get it done.

That swap might save me from spending money on a Northstar. I hope that someone does it and sells a Kit for it. It would make my day. Be even better if the person that did it could use my car...as long as I get to keep it. I want a turbo and power but I also want to fuel economy. Heck...If I could get over 150 in my car and maybe get a better 1/4 mile with a 4 cylinder I would be happy. If someone was to make a kit I would hope it could be under $12,000. Maybe I am hoping for to much but...if you dont have hope, you have nothing.

I am yet another one hoping that the Ecotec works out on the Fiero. While a V8 is still my main swap candidate down the road, the ability to use a light but powerful engine would really make my day. It's not so much for the fuel economy, though that's important. With an Ecotec, I would not loose the balance that the Duke -- for all it's weaknesses -- provides in terms of handling.

That said, the allure of a torquey N* or LT1 may turn out to be irresistible come decision time. Then there's the unbeatable experience that people like Archie bring to the plate. Hmmm, maybe we can convince HIM to get his hands dirty in Ecotec grease...that would be something!

I'm in it for the reliability and accessories. The Ecotec seems to be bullet-proof and there are quite a few easy upgrades for it resulting in a pretty potent engine in a small package. What I'm most interested in is if anyone knows of any mounting problems or kits that are out for this conversion. Also need to know about any ECM problems because I know that 2000+ applications such as the Sunfire and Cavalier network the ECM to other features in the car and if it is not networked properly it will cause a no-start or driveability problems.

As for gas mileage, it's not a concern. Thanks to all who have replied and let's keepthis rolling until we get some answers! Thanks!

I found this turbo kit: http://www.cavalierconnection.com/BaseTurbo.htm

Joshua : Look @ the horsepower to weight ratios, what was the ecotec in, what's the hp/wt of all three?
More ponies per pound =better performance, and if you keep your foot out of it, economy.
With the ecotec weighing less, it might do better than your TDC.

Very interesting--So does the 2.2 bolt up to the Fiero Auto? Also what about cost of an Ecotec engin--complete, wireing,ecm and all?

I'm not sure, I've never done an engine swap before, that's why I'm hoping some engine gurus in the community here can shed some light. I know the physical size will fit. I'm more of an electronics guy, so I'm looking for helpon the mechanical bits. I know I can rework an ECM to be suitable, etc.

Wasn't the Ecotec supposed to be available from GM as a crate engine with its own stand alone engine computer and wiring harness? I can't remember where I heard or read this but if this is the case then I'd definately be interested. That way the money you invest in an engine swap goes towards putting a brand new engine in the car.

The Ecotecengine is also used by GM racing in a Cavalier and Sunfire.They have the engine putting out over 1100HP with 40 lbs boost.I talked to one of their tech guys at Atco raceway Saturday,their trans is a 4T65,but their modified version (which holds all that horsepower)can be bought for $10,000.

Here is some interesting information on the Ecotec from GM part depot. It seems that they haven't set the price for the crate engines yet. They have several high performance parts available with pricing. Here is the link http://www.gmpartsdepot.com/store/category.asp?CustomerID=366388&ACBSessionID=xDtONO7cNjMMsF5d0KiR&SID=8&Category_ID=16

Now you can sense some of my excitement..... Just in base form fromt he stats I've uncovered, the Ecotec puts out approx 140HP. You can get both supercharger and turbo accessories pretty decently priced which seem reliable (heck, GM offers a bolt on supercharger for it right on their site). If anyone here has some engineering skills it would be great if you could look at the engine and at a sample fiero to see what mounting problems we may have. I'd be willing to supply the Fiero and engine if needed, just need to know where and when to drop it.

I'm driving around in a Chevy Cavalier rent car this week with an Ecotec and the engine feels reasonably strong for a 140 HP/150 ft-lb four cylinder with an automatic. Motor Trend reports an 8.2 second 0-60 time for this combo. The 2002 Cavalier with an automatic and the 150 HP/155 ft-lb 2.4L Twin Cam did 7.9 seconds for 0-60 mph and 16.2 seconds in the 1/4 mile.

The Cavalier weighs a bit over 2600 lbs which is similar to my Quad 4 Fiero. My high output 2.3L Quad 4 Fiero definitely pulls better at 5000+ rpm than the Ecotec and is a noticeable up in performance from my 88 GT with a stock 2.8L.. From the numbers it looks like the base 2.2L Ecotec will be about equal in peformance to a stock 2.8L. Now if the 2.2L Ecotec engine can be turboed for reasonable money it could get impressive.

Click here. Read through it.

And now to add on to what you guys have just said...

GM doesn't yet separately sell a supercharger for the Ecotec, only for the Quad 4. When the Saturn Ion comes out, that will change though.

The Ecotec crate motor is $3,500 at www.paceparts.com

The RWD Cavalier drag car puts out 1,200HP.
------------------
Basically, to put what an Ecotec Fiero will do into a nutshell...

Vehicle balance will be as close to 50/50 as you can get (all aluminum motor with a block weighing only 69lbs), total vehicle weight will be lighter than that of an 84 2.5, the lightest of all Fiero's, and a lighter vehicle means better MPG, acceleration, cornering, steering, braking, and less tire wear.

My HP goal for this motor is 500HP, and with the T3/T4 turbo I have, that should be no problem.

Free bump

Has any ever put a 4200 Vortec motor in a fiero?? the Inline 6??? at work they are in a few vans and they are pretty quick for a heavy van. and hte motors are extremely reliable (some of the motors at work have 180k miles) and the gas milage doesnt seem to be bad even though i havent clocked it.

It wouldn't fit. Not unless you mount it longitudally with a porche or olds toronado tranny, and at that point, you may as well get a better motor than that, like a BMW V12.

Forgive me as I am new to all of this (esp. hi-po GM 4 cylinders), but why isn't the Quad 4 more popular...and what kind of mpg do these achieve?

The quad4 has a stigma similar to the Fiero... a peice of crap... when the motor came out they had an above average occurance of blown head gaskets. The problem was fixed at the factory but the damage to its reputaion was done... just like the Fiero fires.

I've got a problem with the speedometer on my Quad 4 which is punch list of things to sort out. I've got about 750 miles on a '94 175 hp crate engine that I bought from Mantapart. On the highway it's getting about 30 mpg but that based on guesstimated mileage. I'm driving a 2.2L Ecotec Chevy Cavalier rent car this week. It got 32 mpg on the first fill-up. Most of that was highway driving at 75 mph.

Does this 2.2L have more than 2 valves per cylinder? Not that it necessarily matters with the right set up. When I read "65 lbs block" that got interesting.

The ecotec has 4 valves per cylinder.

Why not spend the extra $2,300? http://www.turnkeyenginesupply.com/22290.html

I seem to recall that the Ecotec that GM promotes as their competition package uses a short stroke crank, etc. so that the result is a 2.0 as opposed to a 2.2. I'm not sure whether they use the shorter stroke to meet homologation requirements, or for other reasons (e.g. reduce piston speed - higher rpm, or?).

FierOmar

It seems that Fieroturbo is the only guy attempting to put in the Ecotec. I am so ready for this engine. I just love the close to 50/50 weight distribution and also total weight. I want to keep my Fiero a 4 Cyl, and this looks like the likely engine to swap it with. I will keep looking for others so that a kit will be built or at least some great instructions.

I, too, would like to do this swap. I am waiting for the availability of wrecked Cav/Sunbirds to pick up. I think you need to do the engine, tranny, ecm from a donor to make this really work.

Fieroturbo, mention in his build up thread that if you have a manual transmission, it will work.

I have a manual, so I don't think I need a transmission. If you have an auto, you probably would need the donor transmission.

I have an Ecotec and the head has some work, larger valves, cams (very mild), ported head, timing gears, springs, locks, retainers. It runs high 15's with heavy 18 inch wheels and Bridgestone Fuzions, plus other minor bolt ons, my car is a 3200 pound pig Grand Am. I should have been more aggressive with the cams.
I love this engine, it is so smooth and way better than my old 2.4TC, power delivery comes on so even. If you're gonna go big power, GM broke all four rods at exactly 283 hp.
It would be great to see one in a Fiero.

Well, it looks like I might have just screwed over my Duke.. The valve cover gasket is gone, there's no oil, and it's knocking. If it's severe enough to warrant an engine swap, I would like to go with a 2.0L Ecotec SC.

Where is a good place to buy one new, and what kind of money am I looking at spending if I go this route? I don't know enough about engines to swap it myself, so would have to have a shop do it or find a friend that might be able to help.

I haven't seen anything new for a while on any Ecotec Fiero swaps - what's the latest in the Fiero community?

http://www.gmgoodwrench.com/perfpartsjsp/partlist.jsp?section=ce&cat=9274

i can't find the price, and you have to scroll way down to get to it, just start from the bottom and work back up, but the 2.0 S/C and 2.2 are on there.

FYI, the Ecotec will work with an auto, but a flexplate spacer is needed, which I have someone doing R&D on as we speak.
----------
Sorry for the lack of updates on the swap guys. I've been busy with Navy life and all.

The latest is this:
-the engine-to-tranny adapter has arrived
-the 4.10 4-speed has arrived (yessss!!!)
-the bottom end engine internals are in Texas being balanced
-and the head is going to a machine shop next week to be machined

Cheers mates!
