Looking to put a supercharger on my car. As of now I have the 99 ld9 and I love the motor. There is not that much aftermarket support for this motor and I'm looking to build one to about 250 hp. Now they made a kit in 00 but used ones are rare and a new one is about 3 grand not to mention the head aches with the pre 00 ld9 re flash and egr block off. If I go with the Eco there is more support and the cobalt s/c bolts right in. I'm sure I could do the supercharger with proper tune on the Eco with less problems than pre 00 ld9. The swap will not be an issue I'm just wondering which setup will be easier to work with in the end. Also wondering how much boost the 2.2 eco can handle with stock internals. ANY help is appreciated thanks
if the swap's not a problem find a low mileage eco and boost it. that would be your first issue is the fact that your ld9 is probly tired by now.
you answered all your own questions. beside's, m45's suck.
have you considered putting the m62 on your ld9? not sure what lack of aftermarket support your refering to
The LD9 has plenty of aftermarket support. You do not need a built motor to get 250hp out of a LD9.
I'm at 219whp with my 130k LD9 with a M45. I still need to get it ported.
As for tuning the 2 with boost well really the LD9 is only slightly easier. Because you can use the GM reflash. You also have the option of a 97 speed Density tune. So your year LD9 has a few more option. If your tuning the stock factory ECU with no reflash, the LD9 and a Eco are the same in regards to how hard.
As mentioned you could put a M62 on the LD9.
The one thing the Eco has going for it is it has a few options for a M62.
Also a new M45 shold be around $1400.

I'll be honest I'm new with the ecos and I've heard they have more aftermarket parts/brands correct me if I'm wrong. My ld9 is not tired it runs very well and new tran and clutch like 60k ago. I have no idea how many motors of either are on the road but it seems like the eco will be easier to s/c with it being a newer motor and the the cobalts m62 bolts right on. This will make it easier to work incase something breaks. Don't get me wrong I love my ld9 to death but I don't want to turbo it. I've seen a m62 manifold for 2.4 go for $500-600. Is it worth the swap or should I build up and buy the m62 manifold. ... I'm just worried about a good tune and a properly running m62 ld9.
People like to say the Eco has more aftermarket support, and there might be a couple things like a forged crank that you can get for a Eco and not get a LD9, but not like you are saying.
Tuning aspect the LD9 has a slight lead because of the different options, but it all comes down to who is tuning the car also.
Seems like you already have your mind made up, so go with it.

I don't have my mind made up at all that's why I keep asking questions. My ld9 is still mint runs very well and the car is well taken care of. I wanted to see what people think is the best to do. I want to put a m62 on the ld9 but I'm afraid of the issues I might run in to. If your saying it won't be that much harder than the Eco I will do more research on the subject. One more thing can I take the cobalts m62 and bolt it onto the 2.4 m62 manifold. The 00 gm kit looked like the s/c was attached to the manifold. I'm noob be gentle.

Yes the M45 for the Ld9 is a one piece unit.
You can use a M62 from a Cobalt for a M62 manifold on a Ld9.

If you're thinking M62 I think the toughest thing for the LD9 would be finding a manifold or custom making one. There are only a few floating around that I know of. There's Vulcan but you're not gonna pay $500 to $600 dollars and I could make and deliver a baby quicker than it takes for them to actually get you a manifold. (honestly. it was over 9 months). Being a 99 couldn't he swap to a 00 - 02 ECU and run the GM reflash? Not exactly sure what's involved in that. The eco swap is some work, sourcing the parts, paying for those parts, finding a proper place to install and then still having to tune it anyways. In my opinion the easier/less expensive route would be sticking with the LD9 if you can find a manifold. Just my thoughts.

Used ones are not rare. There are usually a couple in the JBO classifieds alone.

Next...99's do not have an EGR, so no block off plate to worry about

My cavalier was manufactured in 02/99 and it DOES have an EGR. Since this IS the case that means my ECU differs from the 00 so the reflash is not possible? Ill be honest the work doesnt scare me as much as the actually tune for the car. I cant imagine putting all this work in and my car run like a bag. From what I've heard pre 00 need HP tuners to tune. If i can tune the car easier with reflash from GM maybe I could swap the ECU like dcampbellz24 said. I'm looking to do a reliable m62 s/c setup on the cav, what ever is easiest to do and maintain. Thanks for everyone who posted and you were all a great help. If anyone has anymore input I would really like to hear the opinions!!
My friend had a 98 cav sedan LD9 with an M62. We had it tuned in Toledo by pure tuning. It was a few hundred for a tune and dyno time, but it was worth it. It ran awesome.
I'd do that.

You will not get a GM Dealer to put the GM reflash on a 99 unless it is a friend working at the dealer. The Dealer will say this car can't be reflashed. A 99 can use the Gm reflash, but you will loose some gauge functions. This is because in 00 J's had BCM's which controled most gauge functions. 99 does not have this. You can load a GM relfash using HPTuners, but still will loose some gauge functions.
For a supercharger you can tune using HPTuners and have a good safe realible tune. My best friend has a 99 Z24 with the M45 and I tuned it. He has been running it for about 4 years with no issues.
You could also run a 97 Speed Density file on your 99, but this would also require HPTuners.
You could do a harness swap (interior) to add a BCM to run the GM reflash and keep gauge functions.
Youneed to decide what route your going to go tuning wise before doing anything else.
