hope this works

I think I fixed it for ya.

Yes, please post more info on your adapter. Could you supply a CAD file or something like that so we may make one of these adapters for ourselves? That would be great if you could since I have been considering this swap for one fo my next Fieros. (After I finish the 3800SC)

Thanks
Kris

This was your first post??????

I thought you had been on Pennocks for awhile. We had been e-mailing eachother for like 4 months now, and I got the gist that you were a regular here.

Shows how zoned out I am...LOL

Anywho, do you have an OEM Ecotec wiring harness? Cause if you have one you can actually just use it, and the ECM attached to it as is, with no mods, except for the "on" "start" and other ignition switch wires (the motor will run, but speedo, tach, etc. will need to be custom).

Also, what's the deal with the flexplate spacer for the Auto tranny setup? Didn't you say it needed a 5/8" spacer?

here's an interesting question, if the ecotec can bolt to our trans with an adapter, would that mean that a fiero engine (or something with a similar parttern) be able to bolt to an ecotec tranny with an adapter? Personally, i see the ecotec's gears being a great option for people with say a 3.4 DOHC or something like that.

the flexplate will not be moved with a spacer now , because the starter head is not long enought to contact the flexplate teeth so the solution is add a 5/8 " boss to the 3 torque converter bolt wholes on the converter this will allow the converter to lock into the transmission an move it 5/8 away from the flexplate to make up for the adapter plate thickness ,i have talked with some torque converter makers an a longer converter front locking spline would be custom an costly an a custom made wider converter would be costly, the GM race division is welding a new longer boss on to the converter it self an taping new threads an using longer bolts thru the flexplate, this same adapter plate is what used to put the 4t65e GP in the GM race car because the cavalier trans. were breaking the chains inside above 550-600 HP , i have 2 more adapter plates already cut an i do not have the cad files in my computer it cost me $65.00 per hour an was a 4 hr job to make the cad file an clamps to hold the aluminum on the cnc machine , i have another picture with the Fiero trans. bolted to the engine

WELCOME TO THE FORUM!!!!!!!!!!!!!!!!!!!!!!!!!

Thanks for all the info on the ecotech......more please!

How much do you want for the adapter plates? If you want, I can post the other pics for you. Send them to krisjune@sbcglobal.net

Kris

I may be dense but--do you have your 2.2 mounted to an automatic transmission? Also what about the engine mounting points and brackets? A simple kit whit these parts available and instructions would be a hot seller for us 4 banger guys.

I know the adapter will work for any GM front drive bolt patern, but please tell me you are adapting the Torque converter for a 4t65e or 4t60 and not for the 125.

------------------

you need to find out what size converter is stock for the donor car then work from that to increase stall size but be prepared to give up a little gas milage , i know what the fiero T125 came with , the 4t65e, i do not know ,now i do like the idea of the 4t60 overdrive as a FREEWAY cruiser running low RPMs but the mounts an axles has always pushed me away, the Ecotec adapter plate is $375.00 at this time an at a later date it will come with the front mount an bracket an a torque arm bracket to put it on the Fiero craddle ,this will increase the cost , this way we can just change the engine to this 305 lb Ecotec , think about it a 90 HP iron duke or 50 more HP added with the Ecotec, totaling 140 HP an less weight, an in a couple of weekends back on the road

These are some photos of CETICARS, project. BTW, are you the one that is going to be building and selling the adapter plate or do you have a supplier?

(I just got back in town. Sorry that it took so long. I am not able to post photos from computers at work).

This is good

I was just wondering how it is coming along.

taking the orginal bottom engine bracket, under the crank pulley an making a pattern for a new fabricated bracket that will use the Fiero V - 6 craddle mount to mate it to the craddle , getting the height of the engine bracket to craddle level an making a torque support arm so it does not move to much when you gas on it , i will have some pictures soon

got ripped of so now i am looking for a ECOTEC wiring harness the person had alot of ecotec parts on ebay , an i asked if they had wiring harness so i paid them $300.00 for a wiring harness an computer , some bolts an related items an they sent me a borke transmission mount that i did not order an when i catch her on line now she get off i asked her to send my money back she said did not reply , so i am now looking to get a harness an computer , stay away from this email selling adress also on j / body web site selling ECOTEC parts : ModerNxEvolution@aol.com

At least give her a bad rating.

I'm not trying to criticize your project or anything but was wondering why are you going through the trouble to update to such a great engine and body kit and leaving the TH125 intact?

------------------

Upgrading to a overdrive transmission is great , but to keep cost down an the adapter plate would let you just change the engine , some peoples cash would not let them do a trans. , engine an axle swap ,an for most of us the T125 has done a great job , still with us after 15 - 20 years of service , with minimum problems ,some of the new transmission now only last 7 or 8 years an it need replacing ,i have been working alot ,all the Deer hunters on my job take vaction this time of year an this is the last weekend of deer hunting ,so i will be getting back to the install this week , front engine bracket is made an the mount came in yesterday $29.00 from advance auto parts , i do not like the cavalier trans. an you would have to get the axles , hook up the speedo , & it has eletronic set up , i think some trans. mounts, brackets & relocating will also have to be done also, who have pictures of the 4t60 overdrive none eletric bolted to a craddle ,do it use the same mounting wholes as the T125 , show some pictures

OK I see. Was just curious. Keep us posted on the progress.

------------------

Just getting back on the project ,i went an pulled a wiring harness & computer today from a Saturn L model 2001 the computer box is a little different from the 2003 cavalier computer plugs the other plugs are the same an it will work , i will strip the extra wires out this weekend for the headlights an wiper motor , where is a good place to host pictures that will say up for a while an for the OVERDRIVE guys you can use the stock transmission an not use the adapter plate i will post some pictures after the weekend

Is it possible to use the cavilier tranny and if so what can be done about axles

i am not using it ,if you use it post the info on the axles an how you made the brackets to mount the tranny an where you changed the bolt wholes over on the craddle to fit

guys , i am back on the engine mounting just got the rest of the accessories also an ordered all new bolts for them , i lost $340.00 on the first harness deal,i got one from somewhere else ,the next step was the torque converter , i have tried several things an the best solution for the install is to get some torque converters made , the reason is it need to be 5/8 thicker so we can use the stock Ecotec starter ,so they will be a 5/8 thicker , 2200-2400 stall size, compaired to the stock 1600 converter that come from the factory in the fiero an the new Cavalier , Cobalts an Saturn Automatics ,THIS SHOULD THROW YOU BACK IN THE SEAT , OFF THE LINE LIKE A ROCKET

Just curious to the bennifits of this engine? Does it have alot of horsepower/torque? Or is it really good on the fuel economy?

They are 140-150HP & 150 lb-ft of torque, that weight less than the iron duke 90hp an get good gas milage ,gas here is $2.00 a gal. this will be a daily driver for me with a body kit on it , the engines are great replacments an cheap an GM is making aftermaket performance parts , the stock engine is good for 265 HP .You can use turbos & supercharger on this engine an they come from the factory with them both ,the turbo is in the new sabb an the supercharger is on the staurn ion redline both at 205 HP , an without these items how would you feel about 55 extra stock HP behind your head , i plan on superchargering it later when use parts start showing up

Please! I hope somebody does this with a manual transmission. I hope they can bolt up as easily. Will put this one on my star list.

The call came in thrusday evening they will make the torque converters for me as long as i do 10 at a time and i pay for all of them up front so i agreed to do so ,the flywheel spacer was not the best solution required a longer starter head , an for all that want to know, the tit in the middle of the torque converter must be supported by the flexplate ( Automatic ) otherwise it would break the flexplate bolts out where they attach to the torque converter ,this is the last stage before pictures an packages will be avalable ,this will have the adapter plate, the 2200-2400 torque converter, an front an side engine mount an brackets ,working on pricing NOW. ANY QUESTION ,POST THEM ON HERE

I was wondering what you were going to do about that. I see a lot of truck transmissions at work and almost all of them use an adapter mounted with the flexplate mounting bolts to move the pilot hole out to where it needs to be. It is a good idea to lubricate the snout of the torque converter where it goes into the pilot hole. Any binding will eventually cause the flexplate to crack.

with the modifications to a NEW torque converters , they will cost us $150.00 each ,an i will be paying for them in advance ,i had to put a deposite down on an order of 10 an they are making a re-order no. ,i tried to get them made where the GM RACE TEAM GET theirs but that would not work because of the deal with the race team ,so i was able to get the same specs. at another place ,they will be 5/8 thicker to make up for the adapter plate an will work with the T125, 4t60,4t65e an they will do lock ups for electric control also ,i will only get 1 out of the 10 ,they will be stall speed 2200-2400 compaired to 1600 fiero an cavalier an 3800SC an if you need one for just a stock T125 on the iron duke its $115.00 for it ,this is the last piece ,i will be setting a PRICE for the ECOTEC TO AUTOMATIC TRANS INSTALL in the FIERO in a couple of weeks , i will try to make it as cheap as i can an include all parts needed for the home builder. ANY QUESTIONS OR COMMENTS ,PLEASE REPLY

if i didn't have to work for a living , i could have been thru several months ago ,but my hobbies would not support me an my 4 kids an wife so work is a neccessary evil $$$ !!!

i was originally set on doing a 3800sc swap, but the economy and potential on this engine seems like a better choice for me. i would be really interested in a kit and will be waiting for the price. thanks for all the info, peace

You are welcome,with GAS PRICES peaking an the end of May ,when the Vacation season start ,gas will be high all the way thru the summer ,an when gas come down after summer to $2.00 or $2.15 we will be glad to see that ,i start vaction thrusday of this week , i will try to put all these pictures i have taken up on the forum , these ECOTEC ENGINES are popping up on ebay weekly ,we need to find a supercharger intake ,because EATON sell remanufactured superchargers for $900.00 i wonder if you could go to SATURN an just order the intake

Ok so you have me interested..... Let me see if I understand the front mount. You are using a fiero V6 engine bracket attached to the ecotec and engine mount attache to the cradle? LMK if that is coorect. Did you have to fabricate anything for the front mount? If I didnt understand that part correctly please discribe the front mount again. I would really like to do this swap.

I am using a large trans mount for the engine mount , i had to drill 1 new whole in the craddle where the fiero v-6 front mount fit , an then a stabalizer bar an the dog bone , i listed the mount part no. in one of my post , i have run into a problem starting it , i was told i need to get the instrument cluster to bypass the onboard alarm an i talked to a company in the UK they have a remapping program to increase the air an fuel an increase the rpm limter to 7250 an if you add better exhaust you would be around 160-165 HP ,i cannot wait to get back on the road
