I am thinking about running a sequential turbo setup on my 2004 Cavalier. Yes I do know that I can probably make the same amount of power and achieve the same track times with only one turbo but I just want to do something different. What's everyone's input?
It beats a Honda!
if its what you want to do then have fun, its going to cost more
Doing something different is cool but not if being different is the only benefit. The time and cost of this totally outwiegh any benefit IMO. I am sure you can think of better ways to use your time and money to improve your car.

Don't do it! I want to be the only twin turbo cavalier in the world.
It wouldn't matter for low end power anyways.

It wouldn't matter for low end power anyways, if you're racing because if its sized right, the gear shifts around 3600k anyways... so you would get less air heatup because of the greater efficiency zone. the car isn't RWD either so you wouldn't benefit from the "fun" factor.

who in the hell shifts at 3600 rpm, while racing?

Two words:
Variable Geometry
I can hit 30psi in fifth gear at 1500rpm with a flick of the pedal... talk about compressor surge.

Obviously you don't understand the purpose of a sequential system. 2 turbos 1 small one large. The smaller one gives boost early on until the larger one spools. Its how they turboed the 3rd gen RX-7's and why they catch on fire. Blowdryer into the back of another blowdryer. Its not worth the pain when you could probably spend less and have a VAR (variable geometry) turbo setup and still be unique.

I think he drives an automatic mabey that's why he shifts so early, I don't know.
IamRascal what's this about RX-7's catching fire? Both of my turbo's will be directly plumbed to the manifold, so one wouldn't blow into the other but I'm still intrested in the RX-7 info.

If he's on the gas it still won't shift at 3600 even with an auto. He's just a moron with little to no clue.
I used to race cars, now I race myself.

i think he meant that when you shift, revs drop to about 3600rpms..which there is no point for a turbo for the lower rev range.

that's what I figured too

That's not sequential, that's unequal parallel, and it's also the worst idea of the three.

better a delay than a disaster.
from personal experience, if you have too much boost at low RPM's it just sucks, terrible fuel milage, and I would rather rev the engine up instead of torqueing the crap outta it at low end.
and look at a TT supra... first power upgrade is a single turbo. If it is a daily driver and you HATE, I mean HATE oil leaks, exhaust leaks, etc, go single and you will be extremely happy.
I just installed a larger turbine housing to slow down my compressor and increase lag, just my 0.02

This car is no longer a daily driver strictly a track use project as of April 12. Also it would have a new LSD trans, & each turbo will be plumbed to its own Innovative SBC electronic boost controller & IndyGate wastegates.
It beats a Honda!
and its a complete waste of time
i had a plan to have 4 turbos one for each cyl. just as a SHOW ONLY thing
dont think it would help with power much but it would be unique
boost is like ice cream, there's always room for it
If you have a copy of "Street Turbocharging" by Mark Warner, there is a picture of an 8 turbo LS1 powered 57' Chevy.

"Youth in Asia"...I don't see anything wrong with that.
for it to be functional and advantagous, you of course have to have a fully-built engine (rods, pistons, head, etc.), and the turbos have to be matched really well. Since it's a track-only car, it could be alright, similar benefits (in theory) to Josh F's Twin-charged 'Fire. Most people will say that this is just the dumbest idea ever, it's a waste of time & money, and blah, blah, blah... if you're really dedicated to this car and just love spending time testing and tuning, and playing around with different turbos, etc., you may have fun. If you think you can just go get a big turbo and a little turbo, and slap them on, then you're a fool; it will take lots of time and money to get it right. personally, I wouldn't do it in a FWD platform. either way, it's your car, have fun!
the bottom line is it better be fast (specially if its a purpose built race car) if u spend all that time and money and u can't get into the 14s than whats the point (don't laugh i have seen elaborate cars like this that can't) u just look like a goof . two turbos are not going to do anything better than one good turbo on a race car and I'm more than happy to give up a little bottom end for the money in my pocket and the simplicity / reliability under the hood of my street car. plus there is no way to mount and plum to turbos on a j unless u do some cutting or stick them through the hood but than u better be running 11s or better. or i will flame u my self lol . don't see the point but good luck
