I am new to the forms not new to the Ecotec game. I have a 2006 Cobalt SS SC a 2003 Chevy Cavalier with a m62 nitrous and a forged 10 to 1 compression engine and a base model 2007 Cobalt LS that I was thinking about a rear-wheel-drive swap in.
Welcome. Rear wheel drive is a very ambitious and involved project. Personally if I desired rear wheel drive I would probably start with a different platform and just do an Ecotec swap in it as you seem to be an Ecotec fan.

negative ghost rider. Lol. Its not hard to drop a carbed 5.3 in it. 240sx rear cradle will fit with some mods.
would be a cool project! definitely created a build thread if you attempt this
I mean it's been done with the gobalt. I'm just not going to put a v8 in it and leave it stock. Basically a carb intake and hei 1 wire distributor to run engine. Turbo 350 or 700r4 is vac controlled. Hardest part is trans tunnel and rear end.

Gobalt used an GTO drivetrain. LS motor and GTO rear end
to a point. You also got to think wiring nightmares and the tuning is easier but harder. Don't need to hook up a computer to tune it but I don't get the fancy scanners. Also bypass all them engine safety features. There's a Reason we all run carbs on track cars
try starting a carburated vs fuel injected motor when its 32 degrees outside
Lucky my trucks carb so far only had needed a slight idle adjustment between 90* and 20* to start. 3 pumps for 80+ 4 pumps for 50-80, 6 for below 50. Starts up almost every time. Sweet Japanese engineering.

Not many people run carbs on track cars anymore other than hobby/entry drag. It may be simpler"ish" to tune but your never going to get as much power from a carb as a fi vehicle, and they aren't much of a wiring nightmare if your looking at track only. Actually quite simple setup when you compare how mechanically complicated a carb is to basic fuel injected wiring. Gets really simple when you start looking at the newer self learning tbi stuff.
But to each their own I guess.
NASCAR, INDY, Top Fuel.... All fuel injection.
Trust me... I can rebuild most Holley & GM carburetors blind folded. Many shops closed their doors in 1980. I embraced the technology and would never go back.
Pikes Peak hill climb is almost 100% Fuel Injection now (some electric) because your engine re-calibrates fuel and timing as altitude changes... and it is a significant altitude change. You cannot set a carburetor to run effectively at 6000' and 14,000'.
sorry man I should have clarified. Drag racing. None professional level. And tbi is still carb. So I can run a Holley efi carb in it. And I don't have to worry about adjusting for altitude as I will only be racing in my state.
Throttle Body Injection is not a carburetor... Holley put EFI in a carburetor shaped housing so it would bolt down to a conventional carbureted intake manifold.. It still takes their ECU to run it.
It would still be a electric carb. And yes it takes their 4 wire ecm that control just that. Not the 3 computers from the new cars the dash wiring toggle switches engine wiring all that. Just a simple drag car is all I'm going for.
I'm down with this as long as you call it something cool like frankenbalt or better, since half of your engine will be sticking out of the hood. But TBI is def not carb.

what it is depends on the system your buying it from. For example go to Oriellys and get a radiator cap. Specifically look up a radiator cap. Guarantee you won't find one. And a carburetor by definition is a device in an internal combustion engine for mixing air with a fine spray of liquid fuel. You put 1-4 injectors on it to spray fuel and mix with air makes it a carb. Not trying to start a argument. People have different views of same items. I just prefer the technical name for it.

I know you don't mean to argue, and I hate that I seem to be nit-picking, but my understanding is a carburetor uses a venturi effect to draw fuel to mix with the air while an EFI uses fuel pressure to inject a spray. To me those are completely incongruous. I know you quoted the dictionary definition, but as I understand how carbs work that definition doesn't really describe how they work. When you google "efi carb" all you get are "can i swap my carb for EFI?" answers. Trust me, you don't know how much it pains me to agree with HGT on something
Being as a carburetor is MECHANICAL, a TBI is not a carburetor. Literally TBI is named for what it is, instead of say "Fuel Injected Carburetor". Which would be contradictory.
No one asked you to agree with me. You have your own opinion.
I just watched a video on the production of it and it uses PFI injectors inserted under the bowls where the float would have been on a carburetor.
Having read all of the differing opinions in this thread I will start off agreeing with the statement that if you're wanting a V8 RWD drag car then perhaps start with a different platform. Unless you have the skills to do the majority of the fabs skills (and there are several here who do) then this isn't the car to stat with. As mentioned the transmission/driveshaft tunnel and the rear-end placement are some of the issues you facing doing such a project but they are by no means the only issues that you will face. First you need to set your sites on how fast you want to run the 1/4 mile because it is from there that you start building. Unless you know exactly where you want to end up there is no way to map out the plan needed to get there.
