Is there any way to put a twin turbo kit in a 2.4 cavalier
SEARCH!!!.......theres been several discussions about the same topic. Yes, anythings possible, but seriously.....why? If you were hell-bent on it you would have to do a compound setup (one small, one larger) or if you wanted to do a 2cyl/turbo deal they would have to be identical turbos....which begs the question of why.
If you're asking this question, you don't have the knowledge of putting a turbo on your car and making it reliable and useable.

twins would be damn near impossiable on a quad, but Ive been toying with the idea of a set of 14 's on an ohv. custom manifold, singal gate merged DP. it could workd, there small enough, to where theres massive room in the front.

ya thats what i was thinking about trying on my ohv but then i realized i wouldnt make as good of power so i scrapped the idea
or just go with a proper sized single turbo. If you have the patience anything can be done and if you feel like moving things around in the engine bay then sure it can be done.

Using one properly sized turbo will yield much better results and will be much easier to package, but twin turbos on a 4 cylinder can be done if that's what you want to do, as you can see:

twins on a 4 is a waste
buy a bigger single turbo.
these are two different twin turbo set ups for an SRT-4
this is the dyno sheet for the second set up
the 2 small turbos spooling up fast makes for a lot of power so its not all bad, but you can get more power from a single large turbo, but it will take longer to get thrown back in your seat.

yeah, twin charging is a waste to, so they said lol
i mean seriously i think it's a cool idea, either way your going to be making power so why not? obviously it can be done as seen above.
There is only one case in which twin would be feasible on a 4 cyl: to reduce turbo lag with a huge turbo.
The way this would work would be for there to be a pressure gate controlling the flow of exhaust gases (when the pressure exceeds the capacity of the little turbo, the gate switches to the large turbo). This is anything but easy to do though, you'd be better off with clutching a supercharger and adding a turbo.

..or just run a bigger turbo
why stuff all that piping in there, over-complicate the hell out of things
just run a PROPERLY sized single turbo and your car will be golden.
I don't understand this fascination with fake performance in the interest of 'being different'
o yea, well i'm gonna mount my ecotec the opposite way around JUST TO BE DIFFERENT.
lame.
run 4 turbos while your at it.
ok your preverbial straw just broke my hairy double humped back.how is it that cavalier owners are shooting down an idea to do something different because its "innefcianet".
hey Ive met you before your name is pot right? we went to high school together my name is kettle.
I mean if you want to play that game then whats the point of buying a cavalier? I could think of a million other ways to go twice as fast for half the money. and to that argument what would be your saving grace response? well its different...... you dont see fast cavaliers out there. and whats more, people need to stop looking at peak horsepower and mature there thinking a bit. when you look at a cars power you need to focus on the whole band and where it makes its power and how it makes that power.Not just that last 2000 revs of glouris numbers. most of the keyboard monkeys on this site cant comprehend that a 400 cavalier is probably only going towards the very end and going to feel like trash on the street. Trust me on this one its not that great of an experince. theres nothing and just like that a heavy pull then smoke. its so hard to get to the ground. if you want fun then you want useable HP and TQ.
now yes a properly sized turbo is going to make more midranged power then the twins bust so what, why not experiment with twins to see what kind of TQ numbers you can rip up. what a leming style of thinking for such an unleming style crowad to just go ahead and do what every one elese does. I guarntee you that you can make a differnt HP/TQ numbers in differernt arears then with a single. and if nothing elese you did something different. and dont even try the is defferent worth the big bucks argument, becasue if your really attempting this then you probably know what your doing and you could probably peice the whole damn thing together reliably for well under a grand.
So I say if you got it go for it be different and if its a failure then so what half the fun if puting the damn thing together with some buddys and beer.
oh and generl tso's chicken youve got to eat chinse food during a build its like a rule or something.
and this wasnt an attack at just one monkey, it was an attack at all of you monkeys.

ya it is pretty easy. I see twin turbo kits for the 2.4 here and there on e bay.
I just saw how I spelled inefficient wow

lol that was pretty good. i honestly would twin turbo my car just for the fact that i like to be different. could people still beat me, more than likely, there is always gonna be someone faster, its the cold hard truth. but i like the idea of having something that no one else has.
that is my personal opinion!

Can't say I've ever heard of a turbo that will make power from 2k-7kish. It may just be me, but that seems like a stretch for a single.

Actually the whole twin turbo idea sounds pretty cool. By using smaller turbos, theres less lag. And being twin turbo, does the psi add up or not? I'm not sure but if it does thats another reason, just as much power as a bigger turbo. It kinda makes sence. But the whole 8 turbo setup, that crazy!! It's cool looking and all but dam! Thats a little over kill, lol
horsepower is the force that determines at what speed you hit the wall, torque is the force that determines how far you take the wall with you after you hit it.

Like I said, it can be beneficial, it's just a matter of doing it right. If you just slap two turbos on your car, you will have increased airflow but not pressure - and the smaller of the two will limit how much you can push. Twin turbo is really a race-only thing on a 4cyl.

psi is psi , having twins wouldnt double the psi , just the total amount of air
What's hilarious is I've seen better spool with the same peak hp as the dyno that was posted, from a single turbo.

So they said, and most of us still do. All the work of twincharging for the 230 hp that Josh wound up with seems like a waste of time to me.... Just because it "works" doesn't mean it wasn't a waste of time and money in comparison to properly matching a single turbo. I don't know why I even bother arguing because its only going to fall on deaf ears of the "performance experts" anyway. I still have yet to see any momentous achievement out of a twincharged car that makes me think it "better" than a single turbo setup, unless we're talking about a rally car that could make use of it. I don't take anything away from Josh's car, and I can respect the work he put into it, but that doesn't mean I have to agree with his path and method. Now if he went out there and started making better numbers than someone like Speedracer and running better times, I might cop to it. But so far, I've yet to see it happen.
Twin turboing a 4 banger is retarded, and there's really no way to argue otherwise. Simply look at EVERY factory and aftermarket turbo'd 4 cylinder out there. Twins give you less space, more piping, a more complicated oiling/cooling scheme, more money spent, and more aggravation for what? A little bit more power in an RPM range where you'll never use it except for pulling tree stumps or towing a trailer?

I think a lot of you people who are so concerned with "spool" and "low end torque" need to pay more attention to where your RPM's are at when you feel you need more power. Once you're out of first gear at WOT, you never see sub 4K rpm again until you let up. And if you feel you need more power in partial throttle, here's a thought.... PUSH THE PEDAL FARTHER..... There is NO REASON to make massive amounts of power below 4K rpm in a street car/weekend racer. NONE. That part of the powerband is for things like towing, which is why diesels operate and make gobs of torque in that range.
I've got nothing against people being different or taking a road less traveled. Hell, I drive a Beetle and I have a sick fascination with the OHV motor. But there's a distinct difference between "being different" and "doing things just because you can". Just because you can, doesn't mean you should. And if you're really concerned with getting the best results out of your hard-earned dollars, you won't be wasting time and money on things like twin turbos for a four cylinder. Granted, its still your choice, and yes, a lot of people would consider spending money modding a cavalier just as much a waste as a twin turbo system, but in my mind, there's a distinct difference between confronting the challenge of an unpopular platform, and trying to conquer that challenge with an unnecessarily convoluted setup.
You can feel free to disagree, but in reality, the rest of the world is on my side with this. I don't think you're going to find many, if any, Supra owners who regret taking off their twins and going with a big single turbo. I also doubt you're going to find too many people on this site who think that their single turbo setup feels too laggy. As the great Carroll Shelby once said, "Son, if you've got lag, you ain't drivin' it right".

why is it that scarab always has to come in and make me feel like a dumbass... oh wait i am one.
but anyways... the kit i posted for the SRT-4 is from Darrell Cox Racing. The plumbing for it is actually pretty simple and the oil and water system is pretty easy as well. But thats for an SRT-4, something that comes with a turbo. For a cavi it wouldn't be worth the money, you are right there. I never said i was actually "going to do it".
And I know that a single big turbo can make more power, my srt is pushing close to 550 to the wheels out of it GT35R, but it also running untuned (EMS is expensive as hell!)
and my cavi runs on a 50 trim. well did its down right now, damn rod bearings...

The problem with saying that spool and torque dont make a difference is that were not at CFM levels were your going to get a notcieable difference. In fact I woulndt hesitate to say that there isnt a single member on here sucssfully twined, and even more so, one that is making over 400. so really the only actual data that anyone has to go by is what they think makes sense. (aside from doing really annoying math. ) But what is a given is that 400+ HP 4cyls dont have peak power at a useable RPM anyway you look at it. I refuse to belive that spool time's arent an issue at those levels. And anyone who says other wise hasnt driven a road course with an oversised turbo. and until somone throws down some actualy data with our application as the dummy, everything is just heresay. some just look like bigger winners becasue they can back up there "data" with scientific terms that aww the users on here like fire from prometheus.

well i dont run my car on a road course. i only race down the quarter. but lag is still a problem. but not so much as a road course.
