ecotec 2.2L swap into datsun 280z?

I have a 2007 chevy cobalt engine its an ecotec I was wondering if anybody might know some of the stuff im going to need to convert this into my datsun?
I have the wrecked car this was my wifes but she just wanted a new car and the back end is wrecked
as far as I understand I have to make
1. my own motor mounts
2. my own trans mount
3. use the old wiring harness
4. hook up the oxygen sensors and other neccessary sensors
5. make my own exaust
6. get a new driveshaft made to fit this car
is all this worth the swap?im not looking to go real fast but I know this car got excellent mileage almost 40mpg+ and wasnt that bad to drive

Two things make an old Datsun Z car fun, a small block Ford or a small block Chevy. My suggestion given the work you're facing is close to effort and expense to a V8 swap is trade the Ecotech and get to work. Go to WWW.JagsThat Run ; Mr. Mike Knell has a cookbook for putting an SBC into the old Z most of whats there is also good for the SBF if you prefer.

Makes a car that easily gets 20+MPG, eliminates the computer nonsense, and will eat most anything out there for breakfast, lunch and dinner.

Are you going to try to make the 280z into a front wheel drive or are you gonna try to adapt the Cobalt motor onto the nissan's trans?

I'd opt for selling the Cobalt parts and run with a JTR Chevy V8 conversion, but I'm a little biased. But, if you are intent on doing the 4 cylinder swap, try this website:

http://www.hybridz.org/

They have all sort of sick things to do with Datsun Z-cars. If it's do-able, somebody on that site has probably done it.
Good luck....

i would see if the pontiac solstice trans would bolt up... I say go for it. I am thinking of using the same engine in my S15 when I get around to playing with it. Gas isn't getting any cheaper and you can get tons of power out of these little motors.


This may change some of the V8 guys minds:

Some of those 4 bangers have some real potential. You just gotta be creative.

I'm sorry, but your responses make it seem like you really don't understand what's involved here. The Cobalt is a FRONT wheel drive car with a TRANSVERSE engine and transaxle. You CANNOT use this trans in a RWD car with a longidutinal engine installation. If you really want to install the Ecotec ( and why do you want to install a smaller engine than the one currently in the 280Z?), you'll need the trans and bellhousing from something like a Pontiac Solstice. Also, you can't just hook up the O2 sensor. You need a complete EFI computer to run the injection and ignition on the Ecotec. It's doubtful the Cobalt computer will come close, so now you're looking at a custom computer (such as the MegaSquirt) and custom programming.

My 99 isuzu rodeo daily driver has the GM 2.2 in it and a manual 5speed so you may be able to find a tranny from a rodeo to help out making it RWD. just my .02

well thx for the info I was hoping we could reuse this motor cause the datzun motor was seized but maybe it would be best to sell it because im not real knowledgable on front wheel drives myself

Well my friends putting in the ecotec is a great idea there is tons of sweet stuff for them. Now how i understand it the 60-degree bell housings bolt up so the 2.8 s10 would work. Auto the flywheel works great manual there is a little more work involved. if u haven't sold it yet then donít reed a little more u won't regret the swap.

Land speed cars have done it for years they know what up

The Ecotec is still a bit new so bolt on aftermarket parts aren't available yet. A Quad 4 conversion would be fun in the 280, with a little boost!

talk with a knowledgeable ecotec guy or GM parts counterman.

I think the RWD ecotec engines are a slightly different block design, but I might be wrong (and therefore you are lucky)

I also think it would be really cool... get Colbalt SS/Saturn Ion Redline supercharger for it and enjoy instant, spool time free power!

Also individual throttle bodies would look really cool.

I'm sure you can think of something.

The ecotecs are great motors. I put one in my sandrail and have been very happy with it. It came from a 2004 cavalier. I am running fuel injection but did not use the factory computer. The OBDII controls look for alot of things like smog equipment that i did not want to mess with. My rail has a Megasquirt controling the fuel injection. The megasquirt is nice because you can make modifications to the motor and simply edit the computer to work with them. The 60 degree V-6 bellhousing is not the same as the ecotec. There was an adapter made by GM Sports compact to adapt the ecotec to the 4T65 FWD tranny. I ended up making my own adapter to mate it to a VW transaxle. The ecotec drawing i have came fromt GM sports compact. A good place to look for info is ecotecpower.com . I have thought about swapping one of these motors into my Datsun Roadster but i think the engine would be to wide to fit properly. The Z cars get v8 swaps all the time so this should not be an issue.
