Right now I have a base ls auto. once my warranty runs out I'm planning on swapping an ss/sc tranny in it(assuming it mates up...) along with an ss/sc exhaust manifold. Maybe the ss/sc supercharger and cams depending on what I can find. Mainly I just plan on keeping this a cheap project car, something to tinker with. I know a few people around town with wrecking yards and I usually get hooked up.

Anyway on to the point... I know my ls has a 2.2 and the ss/sc has a 2.0 but from what I can see they are basically the same block and head with different internals and bores. So I figure the stuff I pull off the 2.0 will mate up to my 2.2 right?

Either way I'm probly going to do all this. If I have to make adapter plates I will but I'd just like to get everyone's opinion and possibly some knowledge from people who may have already swapped some of these parts.

so either:
a)good stuff, it'll mate up
b)could probly get some aftermarket stuff for the same price for better performance
c)forget all that crap and shoot urself in the face for thinking such blasphemy.

thx for any advice.

 

well when you figure out the different parts you want to swap, i would go price out an LSJ and see how much it costs vs modding the 2.2L, it may be more worth it to just buy the crate engine.

also, there is a new ecotec coming this year, 260hp and its turbocharged not supercharged, maybe look at that one, see if that would suit you better.

 

OK, honestly, REALLY bad idea. Work with what you've got.

Even if you can bolt the tranny on to the 2.2, the gear ratios are going to be HORRIBLY wrong. You'd be better off swapping for the Getrag that comes in the 2.2 and 2.4s. Every transmission is mated and tweaked to work on one or very few engines with similar power (hence why the 2.2 and 2.4 have similar trannies, both N/A, both in a similar power range, and the 2.0 has a different one that's designed to go on a small forced induction engine). The gear ratios are set to make the most out of the engine's powerband. You put that transmission on another engine and you're not going to get the most out of your engine. Basically: DON'T DO IT.

Same with the exhaust manifold. The only one I've seen is the Extrude Hone one and it seems to indicate LSJ only. So you might have troubles. Again, go with something that's designed and tested to be most beneficial to the 2.2. A manifold isn't really going to gain you that much anyway...

I don't really understand why you chose those two things. Seems pretty random. The tranny isn't going to get you any power and is in reality probably going to cause you to LOSE power. As for the supercharger, why don't you work with the kit they made for the 2.2 Ecotec that came out of the Cavaliers?????? To me that would be the more logical choice and one that might require less fabrication on your part. Also, I'm not real sure how the PCM is going to like it if you suddenly are throwing boost into an engine that's N/A - which is why they include an engine calibration with most kits (unfortunately the Cavi kit's tune won't work on the Cobalt). Again, with cams, why don't you get the cams that are made specifically for the 2.2????

With the plans you listed, it sounds like you're headed for trouble. You need to work with the 2.2l that you have or trade up to the SS/SC. You can't make it into a 2.0 and keep it cheap. It'd be cheaper for you to work with what you have. If you want to do a tranny swap, swap for the Getrag for the 2.2/2.4. I don't know about manifolds, but there are headers and catbacks available for the 2.2. A manifold won't gain you much anyway. Also, they make cams specifically for the 2.2. Use those. Either that or swap out the engine like CivicKiller suggested....to the tune of $5000 JUST for the engine. Not including all the costs of installation....

The 2.2 isn't a bad engine and you've already got one. Work with it. The parts are out there for it, and you're better off going with something designed for that engine rather than trying to Frankenstein something together that probably isn't going to do much for you.

 

first of all I already answered half ur question. I'm going to be doing this as something to tinker with. Second of all... I'm not really the type that minds modifying things. I've done 5 turbo installs on vehicles that previously didn't have a turbo and have yet to purchase a kit. It would be fun to go with a supercharger.

second of all I'm trying to stick to things that won't break the wallet. I know a lot of people with wrecking yards and can usually find things I need for a good price. probably end up doing all my work for around 2000. I'm thinking about possibly going with the ss/sc cams because I figure they will work well with the rest of the layout. If I were to go with aftermarket cams I'd probably just toss the #s around for my own custom cam profile. I dunno if anyone has any aftermarket cam out besides maybe gm anyway(and there's no way I'm paying stealership prices, even at wholesale prices.)

Also I don't really care about going really extreme with this. If I pull 250hp outta the motor I'll be happy. I just want something fun and fully street legal to cruise around in. So I'm not about to haul off and buy a crate motor and all that other stuff. Besides it would be kind of fun to be able to say I have a 2.2 ss/sc. lol

as for the tranny, yes I could throw a tranny in there that's made more for an n/a motor, but why if I'm going to throw a supercharger on it? Throwing a supercharger on stock internals is more than possible as well. I'm not talking about 30psi out of a full blower, just maybe 40hp worth out of a small twin screw. I'm also wanting to go with the exhaust off an ss/sc becuase I figure it'll be a lot more free flowing than my stock one but will still be somewhat quiet compared to a loud cat-back fart-pipe aftermarket exhaust.

If I really feel I need to tune further than a fuel pressure regulator and a map-clamp, I can always go full standalone with megasquirt. Even if it doesn't work with the stock crank trigger wheel it's easy enough to make an external one.

Really I'm just throwing around a few ideas for now. Figuring out what I want to do. I've got a lot of time to change ideas around as nothing's happening to the car until the warranty runs out anyway. Like I said I just want to have fun with it. You guys can go make dyno queens, 8-sec power lunatics, auto-x champions, etc. That's cool push it all the way. This is my tinker toy for later on, I'll save putting my ***** to the wall for my rwd v8s.

 

I don't see why the gear ratios would be horribly wrong. They are a bit different but is not the end of the world.

The gear ratios of the getrag aren't exactly ideal for the 2.4L out powerband goes alot higher.

He is doing it for added strength I beleive. The Saab 5 speed can take alot more power then then Getrag. Makes sense to put a trans with greater strength behind your engine. You won't lose any power.

Just comparing first gear torque multiplication for each

Getrag= 13.74 (3.58X.384 final drive ratio) Saab (3.38X4.05) =13.68

Damn near the same. Other gear ratios might be a little further off but not much

THe extrude honed manifold fits on other ecotecs--and since your adding F/I it would be an okay idea. Afterall--if a F/I 2.0 can use it (LSJ) why can't a F/I 2.2?

Go for it.

 

are your friends with wrecking yards going to be able to get Cobalt SS/SC 's?

 

sounds like fun to me. i found a complete ss/sc front end ,motor, tranny ,everthing still on the engine cradle brakes, struts and everything on e-bay about a month ago woulda bolted right up. went for around $4000 i believe. not cheaper than the crate engine but still a few bucks.
I would try to get the saab 93x turboed version myself if I had access to wreckers. wonder what kinda hackin it would take to shoehorn that in. not much i suppose.I have dreams of awd cobalts myself, but thats a whole nuther can o worms, but hell if we dont have a tunnel already.good luck with whatever you do.
the lsj is alot more than just better cams. it may be the same block ,but its a racehorse compared to the 2.2 mule.not nockin the 2.2 I have one myself. I would get an lsj before i tried to mod the 2.2 with lsj parts. doesnt the lsj have piston squirters aswell as better internals.

 

I have no doubt that the engine built for the cobalt ss/sc is far superior to the 2.2 economy mule, but I'm trying to figure out if the superiority would warrant the extra cost and effort of swapping the motor in there rather than simply upgrading a few things on the 2.2 to suit my needs.

Remember this isn't going to be a full out race car meant to break records, just something fun to daily drive when I feel necessary.

From what I can tell my stock block will be ok to handle what I want to put it through, although I'll probably end up throwing some forged rods and pistons in it for durability and if I feel like adding more boost down the road.

 

I know of two places right now with wrecked ss/scs with the engines fully in tact. I'm not too worried about finding them considering the age market that usually drives them. lol.

 

According to the GM website, the 5 speed on all Cobalts has the exact same final drive ratio, and the only gear differences on the SS/SC is a shorter first gear and a longer 5th gear. 2nd-4th are exactly the same. I honestly don't see how changing the tranny would make his car any harder to drive. If anything, he would get better highway mileage.

Anyway, to the author, seeing as how this is just a cheap project car, I say go for it. I would love to see if you can make something greater than the sum of its parts.

 

that is one of the funniest things i have read on here in a while

 

once again the GM website (USA) is wrong. They have numerous errors including weights.
Look at this page under 2.4L Specs---not yet published??? Funny its been on GM Canada for at least 6 months! lazy, lazy people.

http://www.chevrolet.com/cobalt/specifications/

Go to GM Canada for all the correct specs

Here the correct trans specs.

http://gmcanada.com/english/vehicles...jsp#Mechanical

getrag Saab 5 speed
3.58 3.38
2.02 1.76
1.35 1.18
0.98 0.89
0.69 0.70
3.84 final drive 4.05


Now some you Americans--email GM and tell them what a crappy job they do on theri websites!

 

well I would assume 4th would be the same. It's pretty much the same in every car. lol

I'd really like to go with the ss/sc tranny mostly because it's geared for a supercharged app. and it has an lsd. I deff. don't want to stay auto whenever I start to mod whatever I do. It'll probably the first thing to go. But for now it's deffinately nice to have in phoenix traffic...

 

well the gearing could actually differ between the cars in different countries. It wouldn't be the first time it's happened. Besides, who's to say who's right? If they're the same the canadian site could be wrong just as much as the american site.

 

Sorry but thats just not the case in this instance.. It would just make more hassle for GM to have 2 different sets of gear ratios for an engine with the same power.

Canada has different model content for example, the odd colour difference, french lables inside the door, and primary metric speedos. Thats pretty much the only differnces between USA and Canadain models.

So don't go thinking you have 3.91s and the same gear ratios as the transmission from a Saab.

If I have to dig deeper to prove to you--- I will.


(remember how incomplete the US site is...most of the info under 2.4L Ecotec is not yet published? Lat year they also had the 4.3L truck engine making 300lbs-ft in the specs---but it makes like 260lbs-ft, the weights listed for Cobalts are wrong ect)


The truth is what matters.

 

Heres some data published by GM USA to support my statements.
