ecotec swap (Page 20/98)

Thats pretty cool, that transmission sounds like its geared almost like what my old cavailer was
1st 35
2nd 55
3rd 85
4th 108+

Yeah, I am really quiet sad there isnt more interest in ecotecs anymore, i hope sooner or later there will be because in IMO these are far superior than 3800sc and I think your setup proves it.

If you need help posting pictures let me know I can show you or post them for you.

And by those times I think your putting down much more horsepower than 189, the cobalt ss (205hp) does 0-60 in 6.4, although I would assume a fiero would out-launch a cobalt anyday.

There's still an interest, just a less out-spoken one. There's a lot of R&D that needs to go into some of these Ecotec swaps. (Like wiring and such. Especially for the later VVT ecotec motors.) I'm going to be starting a build thread once the new cradle arrives and I can start taking measurements and a list of what exactly I need to go from automatic to manual, etc.

Also - a Fiero would out-launch a Cobalt any day indeed. It's also lighter by a couple hundred pounds. A stock LSJ would leave the Fiero faster than the Cobalt with a stock LSJ.

the hp rating is off because of the wrong weight being in there .according to what i can find out from from road test data ,the car as is (with the bigger injectors) should pull about 13.5 in the quarter with some launch practise on my part .i really think this is a great motor for a fiero .the more good numbers i can post ,the more believers there will be.

Well as far as wiring goes, I have mine megasquirted, since the motor is not in the car I cannot test it all together but I have done all the major sensors and inputs for it except the ignition, because I have it mounted to the motor now. Extremely cleaned and took about a day of sodering. Im working on this setup to be able to be plug in play for any 2.2 na ecotec put into a fiero. It is extremly nice setup and allows it to be tuned and upgraded later on.

Anyways, WTFB you have any date yet as when you will be going to the track? And do you have the stock 2.2 ecotec injectors right now or the LSJ injectors?

Right - but what happens if you wanted to be able to tune with the continuously variable valve timing of the newer ecotecs? I don't think megasquirt offers a module to do so. You'd have to do a lot of work on wiring to make the harnesses work in these cars. I'm going to start sometime either this month or next in designing a harness to allow the stock systems out of a cobalt to work in a Fiero. Could take a few days, weeks, or even months, but with the ability to phase the cam lobes up to 90* each, I'm going to have to say, that offers a LOT of tuning potential. (I don't mean to thread-hijack here, but I'm just trying to consolidate all the ecotec info towards one thread, so most of it is not lost.)

i think incorporating the cobalt harness into the fiero and making the two harnesses work together would be great .then you could leave the interiour all original .on the other hand i tend to think of my fiero as a platform to be modified so i did not try to make the fiero harness work with the cavalier harness ,i just used the cavalier harness and ecm bcm and ignition switch and instrument cluster etc .the cavy ignition switch is no longer used,just hidden under the consul.now that i am experiencing the kind of power you can get from a 2.2 ,the v v t 2.4 varient doesnt interest me that much.they are a little harder to find ,and have more electronic gadgetry as you know.
on another note ,i saw some 1/4 mile times for the cobalt ss on motor trends website and 0-60 was 6.0 and1/4 was 14.4 sec @93.4 mph .i think i can go 13.5 based on my 0-40 time on one of my runs .
i havent got my bigger injectors yet so i cant go to the strip yet.i dont think they open till may anyway.

I agree, the VVT would be nice, but those motors are much harder to find for the price of a 2.2 ecotec. I would love to get ahold of the 2.4L crank for the extra stroke but the ring on them is not supported by MS yet, it can still be done but its harder to do.

WTFB, I cannot wait to hear some 1/4 mile times!!! I forgot to metion, on the ecotec forums people are selling the LSJ cheap, I beleieve everyone of them that goes Stage 2 upgrade they get to keep the stock injectors, not sure what size they are but quiet larger.

i started another thread on the chat board to get a rise out of people but the gist of it is this:i really know very little about tuning and my car already runs really well .how fast would an eco fiero go with a pro tuner calling the shots? dont like 4 cylinder cars?get over it ,or get left behind .
