looking into swapping the 2.2 ecotec for the LSJ. 02 cavy. can get the LSJ with harness and ecu. need to kknow if it will bolt up to the 02 getrag (reason for keeping:only a year old but a newer getrag is available) and would the motor mounts be an issue? Also are the exhaust manifolds the same to bolt up my current exhaust? i have searched the entire site (not really but def. spent hours) and havent seen anything regarding this. any ideas would be great.
paying close attention to this would love to see this happen...

fixed it for you. not saying its been done but what happens outside these walls is a big mystery.
personally i dont see why you would want to put an LSJ in.. just buy the GMPP s/c kit and be done with it. a lot less work for more displacement with the same end result.
You look so much cuter with something in your mouth.

he is looking to do a 2.2 eco to a LSJ swap. not a hyrid build.
but anyway, nobody has swapped in an LSJ into a jbody yet.
Its basically the same thing, there arnt many differences in the LSJ and the L61 head.
Yea it would be alot easier to buy the gmpp s/c kit but it would still be nice to see someone do something new i say go for it!!
i dont wanna do the swap or the s/c kit but the timing chain tensioner let go on me while burning through the gears. i searched IATN and its not a very common fix on that motor so i guess its just one of those freak things...un lucky me. so the s/c kit is not an option cause i'd have to fix the motor first thats why i want the swap. and buying a new motor then the s/c kit is still more than the motor so the LSJ seems like the best idea (if it will work). the only reason i am considering this is cause a buddy is building a turbo hatchback civic and its gutted and caged so i was planning on showing him whats good with the cavy as i did before i broke and before he gutted and caged the car (b20 w/ gsr tranny)

the L61 exhaust manifold does bolt up to the LSJ head, the LSJ will bolt into the jbody's upper mount (as long as you use the L61 upper mount bracket.. the thing with 3 bolts that bolts to the block itself, and the motor mount connects to that) and transmission (the fit is tight with the oil cooler.. I had to file it down slightly to get it to clear the bellhousing.
however..
you have to use a jbody oil pan or else the lower motor mount bracket won't work (you need this)
radiator hose routing is different, thermostat housing is different. It interferes with the F23 shift cable bracket, there is NO way to modify it to fit. You need to use the 2.2 ecotec thermostat housing, which poses even more problems because it messes up the coolant routing, and interferes with the oil cooler (physically)
the cam sensor COULD run into the brake booster (big problem)
nobody knows yet if the LSJ will work with the F23 transmission. The LSJ is an 8 bolt flywheel, the L61 is 6 bolt. You cannot use one flywheel on the other engine and you also cannot use one clutch on the other (the diameters are different, as well as the bolt pattern). I'm using an LSJ clutch and flywheel with the Jbody clutch actuator (slave cylinder)
there's a lot of issues.. unless you're specifically familiar with both engines I wouldn't even attempt it.
If you were to attempt an entire cobalt drivetrain swap complete with F35, then it could possibly work.. but Idk what the F35's mounting brackets look like but I know they have different mounting points than the Jbody, not to mention the driveshafts are different.. idk if they'd work on the jbody.
and we didn't even touch on the ecu problems. the jbody ecu can't run the LSJ.

I am not worried about the edu, I can get that along with the harness. But the othe info was what I was looking for. Daflyin did you do the swap, kinds sounds like it?

the thread following my build is posted here. Its ongoing, not yet complete, but its nearing the end. But a lot of your questions are answered there, complete with pictures.
the lsj ecu won't work with the jbody either. Unless you rewire the entire car as a cobalt... (read swap the entire vehicle harness)
jbodies have a different class serial communication than the cobalts do. Their electronics got upgraded along with their platform from the Jbody.
I'm fairly certain the cobalt ecu will not communicate with the jbody BCM. thats a bad thing, it'll trigger your theft deterrent, and you'll most likely lose gauge functionality as well. In simple terms, it just won't work.
so in summary, there's no point in doin it. just get another L61. havin the LSJ means it was s/c boosted. buy a s/c kit or build the stock L61 to better specs than the LSJ internals.

just toy with another 2.2 with internals. The amount of money and fabrication to make that lsj set up work would cost more to do than if you built a bottom end for more power than the stock lsj bottom end can handle.

im sure that if someone did this alredy they would of posted it on some car forum. jbo, cobalt forum, whatever.
Im a Xbox 360 fanboy...and damn proud of it!!
I posted a long time ago about this, you'd need a stand alone to get it to run. The crank has different timing marks on it that won't work with the our computer.
Just build the 2.2 and be done with it! Unless you need to rev excessively high I really don't see a use for a destroked engine
