Project Ratty

so ive been doing a little research and ive been seeing some hints of a 2.0 will fit in a car with a 2.2 trans is this true ? has someone here done this before ? (i know turning a cobalt into an ss is rare but its a long term project im looking for)

the trans will bolt up, but the crank/flywheel bolts are different (6 and 8). you would need to get a l61 flywheel custom drilled to an 8 bolt and use a l61/f23 clutch if im not mistaken

what he said I knew it was somthing like that

Project Ratty

would i just be better off just selling the trans and getting another one? sounds like ill just be weakening the flywheel if i start drilling into it( keep in mind this is a long term project around 3 years till i plan on finishing it )
one thing id like to know is if the sub frame is the same from a base modle to an ss? but i beleave its just diff mounts for the trans if im not misstaken

not redrill, you would need to get a custom flywheel made. essentially an existing flywheel, but with 8 holes drilled opposed to the 6

and yeah, the subframes should be the same

i keep reading that you cant put an f23 on a 2.0 or vise versa, however i have never read why. i mean, all ecotecs share the same bellhousing bolt pattern, so thats a non issue. we know of the 6 bolt 8 bolt flywheel thing, however why cant you use the clutch and flywheel that matches the motor? i know for a fact that both the f23 and f35 use the same 14 spline input shaft gm has used on fwd cars back into the 80s. the only reason i can think of that would cause this not to work is the flywheeol on one being physically bigger and hits the bellhousing, or the distance from the mating surface of the block to the fingers of the pressure plate was different, and that would cause issues with the clutch releasing.

has anyone actually tried an f23 on a 2.0l or a 2.2/2.4 with an f35, or is this all hearsay?

Use the clutch/flywheel for which ever motor you are running. Spline count on the trans is the same on either transmission.

If using a lsj motor/clutch/flywheel you will need the trans spacer for either trans. Not sure if you will need the spacer if using a l16/le5 and the f35, most likely not.

For axles you need one specific to the trans.

The front trans mounts are different for the f23 and f35, rear is the same!

If the input shafts are the same on both transmissions then why won't a clutch for an ss work on a base model or vice versa?

Sharkey

the input shafts share the same spline, however the 2.0l clutch doesnt fit on a 2.2/2.4l flywheel and vise versa, they are different designs. and as already mentioned, you cant interchange the flywheels.

I know the flywheels are different but if the tranny splines were the same, the clutch discs should be interchangeable between all the models and I don't think they are. I swear I read somewhere that the splines on one tranny are like 1/32" bigger than the other

i cant confirm or deny that the clutch discs will or wont fit on the input shafts. all i know is ive used the same clutch alignment tool on my lsj as i did on my old 2.8l cavalier, my friend 2.0l turbo sunbird, several different 2.4l, 2.2 ohv, and 2.2 ecotecs, let alone all the gm fwd cars ive done clutches on at my shop. it pretty much covers all gm fwd transmissions (fwd muncie 4 speed, getrag 282, getrag 284, isuzu 5 speed, f23 and f35). really i cant see gm changing the input shaft such a minute amount, they tend to change things like that only if they need to for strength, and they make a decent size change. if it was a strength thing, i would think they would go with a larger and finer spline input shaft.

the discs arent always interchangable between pressure plates. different thinckness of discs and different hub designs may not work with different pressure plates and can cause problems.

you should swap a 2.4 into your 2.2. a member on this site just finished doing this swap. he had to rewire the wiring hareness and a few other things. he even posted pics and did a vid with the 2.4 running. just search and you'll be find it.
