Hey Ben, I just got your email through the site. I am going to answer your questions here, but I am going to send you an email. For some reason I think my emails are all going directly to the spam folder. If you could let me know if my email made it back to your inbox and not spam it would be very helpful
Unfortunately no standalone can successfully control the VVT of the LE5 (yet) but you can do what I did and use a LE5 bottom end with a L61 head. This is 100% bolt-on. However, the L61 cams are way to tiny for the LE5 displacement and stroke. With the stock L61 cams, it drives normal around town but it runs out of air over 4,000 rpms and I mean it just stops revving and going any faster, it is that bad.
I will be publishing a .pdf file for the swap soon on my website. It will be a few pages long but will outline the various ways of swapping an ecotec.
IMO if you are looking for a gas-mileage vehicle and no power upgrades (besides the necessary ones for the swap), the L61 is a better pick. Like I have stated before with the stock MT2 fiero transmission, I got 47mpg with it and I believe with less than $300 bucks in modifications it can run low 15s in the quarter mile, maybe even high 14s if massaged enough, which is quite quicker than a v6 fiero.
About the L61 heads on the LE5... I guess that means that the setup would need custom cams to work well? I don't think the cams can be swapped between the heads.

As you know, I will be interested in one of these setups at some point, and with the way gas prices are going up I bet you'll sell more of these than people will sell SBC kits.
I've said it before, and I truly believe, that the Ecotec is the next SBC. Not that GM won't make some other motor in the future, but I believe that in 15 years or so, people will be driving their Fiero's around with new motors, and this may be the way to go. Not everyone wants to run the 1/4 mile in 10 seconds. Not everyone needs to go 150mph. Some people just want to get in the car, start it up, and drive 300 miles without any issues. And getting 30+ mpg at the same time is a bonus.

I had someone else ask me about that specific vvt setup for the mazda, this is what I was told.
quote
The vvtuner was designed for the Mazda Miata vvt which is a oil pressure type system as well. How the Mazda system works on the intake cam is the only vvt setup. On the intake cam sits the Variable Timing Actuator. It is a simple vane style unit. The housing of the unit is fixed to the pulley and the vane is fixed to the cam. The unit is sealed to protect it and maintains its precision. Right behind the actuator is the OCV, Oil Control Valve. This is nothing more than an electrically controlled oil spool valve. The only thing i have gotten from diyautotune from their support system is that it isn't approved. I am having trouble finding any details about any of it.

I'm buying a low mileage 2.2 head off of craigslist tomorrow. It just kind of fell in my lap I guess. So I guess I'll be looking for a donor with a 2.4 and F23 trans then.

Sounds good, you can run the L61 head on the LE5, just don't expect very much power from it.

Doesn't it just need a set of cams to wake it up? Or is there something else I'm missing?
Nope just cams, obviously porting does a lot as well, for maximum power a LSJ to a LE5 would be the best setup. The L61 2.2 cams are very very mild from the factory, going to the larger bore/stroke of the LE5 makes them even more mild. More duration is what is needed for the LE5
Here are a few more products that I am looking at coming up with in the next few weeks and the estimated cost
Adapter/Spacer to connect the Ecotec to the standard GM FWD bellhousing to use with the Fiero transmissions..... ~$400 .PDF E-book on Ecotec Swap: Choices, How-To, Part Sources, Management Choices, Transmissions, etc. ~$15 Gen 2 Direct Ignition Control Plugs (used for the newer Ecotec ignitions) ~$15 External 7x Front Crank Trigger Wheel ~$100
I have a few more ideas well, these are just a few that are leading the group in "development"
Another option I could come up with is a 6-puck Ceramic Clutch setup would work with the fiero trans/ecotec combo, no cheap autostore stuff.

Bumping an old thread. Looking for a soup to nuts kit which will provide plug and play installation of an Ecotec into an 84 SE. Can someone shoot me a link?

I'd like to swap a LNF (like the one in my Sky Turbo) into me Fiero, or even my 94 S10 should it ever bite the bullet. I hope somebody gets it figured out by then.

You can already buy stand alone Ecotec harnesses that use the original PCM and control all features on the engine. I won't hijack the post and state the source but they are based in California.

what is a 2004 ecotec powered cavalier/sunbird worth these days ? that gives you everything you need .i keep saying , it is not that hard .the problem with most people that work on fieros is that if they cant buy a ready made part or kit , they just give up and say it is impossible .use your imagination and learn how to fab things .no wonder we are getting taken over by the chinese .and fosgatecavvy makes a good product that is proven to work quite well .

wftb, its not 'giving up' or saying its impossible. Its called, working 45+hours every week and having 3 kids. The hours to work on my car are limited. I can turn a wrench and swap some parts, but I don't have time to figure out how to fab up wire harness or engine mounts. That is why I am looking for a kit. V8 Archie managed to come up with a kit to do a V8 swap. I was hoping someone had done the same for the EcoTec.

Roger Thelin makes a kit that gives you engine and tranny mounts and a shifter adapter kit .he uses a method that changes out the front cradle cross member for his own design cross member so some people make their own for that side .the shifter kit is a nice set , but you do have to get one longer cable .Roger's web site is called "Thelin sells" .not much detail but give him a call , very informative .stock fiero manual tranny axles fit right in to the F23 .as for wiring , this thread is about megasquirt control so that is available .i used the wiring harness ,ECM , BCM ,fuel pump and wiring and instrument pod from a 2004 cavalier .disabled the VATS with HP tuners .the ecotec swap is the same as most swaps that are done on this forum - all the stuff is available , but unfortunately not from one source .the next ecotec swap i do (if and when i buy my old 85 2m4 back from my friend Al ) will be based on an early cobalt .and this time i am not going to cut down the wiring harness .i cut so many things off the harness that i wish i had kept . i tell people that are short on time but determined to do their own swap to go with a 3800 sc .it has the most support as far as ready made parts go .for various reasons , i like the ecotec better .to each their own .
