New High flow lower manifold
One look at the reliability, wide powerband and great response of the motor makes whatever you say irrelevant. The LSJ - in stock form, was probably the best 200hp motor available on the market. The great torque and instant response thanks to supercharging is what makes it special.
Yeah turbo motors make power, but most have powerbands that peak way to early and die out up top. Even with the small turbos they can't touch the response and smooth consistent torque of a supercharged motor.
The LSJ may not be the most powerful around, but it sure has plently of driving enjoyment

I agreed that it is was a proven strong motor... and slapping an SC on it did indeed make it a great daily drivable car out of the crate.
However, it's not very mod friendly, due to the fact that most of the bolted on components are at their peak efficiency from factory. You can mod the car, but it doesn't yield the kind of power we should be making, due to a crap IM and a blower that is almost too small.

This site never fails to amaze me... Everyone bitches about how we dont have a aftermarket worth a **** and they wonder why? This should have been one of the first things made for the cobalt...
This car was slapped together quickly. It has a motor that was already used in the turbo saabs with a supercharger kit on it from the cavalier days. Come on love my car but the intake manifold is one of the places gm cut some corners... And a company is trying to fix that and everyone is giving them ****.
I am surprised anyone still designing **** for the lsj...
**** we are on our third generation ricer halo headlight design but god for bid someone tries to give us a little more performance by creating a new intake manifold...

i dont know that whole story so i can cant say anything. I remember the twin screw and it kinda just disappeared...
the engine itself is good... they didnt spend a lot of time on it unlike the lnf... And why would they for 2 different model cars... 3 if you count the atom.

all that may be true, but how anyone feels about RAW shouldn't be the main topic in this thread. I think if you don't want to do business with Rebel then you probably should just pass by this thread. Vendor bashing is not going to encourage anyone to develop products for us. Sometimes it is warranted though. Customer service issues, product issues, and yes money lost on R&D products that never came to be. But everyone knows about the twinscrew and the rad/ic deal. So let's move on from that.

In the meantime SHUTUP ABOUT GM and get on reinventing your manifold, because by the time you are done the rest of the Cobalt world will have moved on and be driving LNF's with 300 hp from just a tune . Oh and GM made that one too.
As I remember it, GM's Performance Division (if it actually exists
they didnt put near the effort into the lsj as the lnf. Stock - stage 2 its pretty good has its lil issues but its stout. Nobody is saying otherwise, but its obvious and has proven over and over again some the stuff like is a little restrictive and half fast.
This shouldnt be about bashing gm or rebel. It took 3 years but the got it right with the cobalt and atleast rebel is trying.
you brag about how gm messed up basically everything, but you don't have crap to show for how you plan to save the cobalt world. some of us were running 11's over 2 years ago with bolt on and spare parts with a little bit of fabrication in the garage.
you can sit on the side and polish up your tentacles and mock everyone for everything or you could get out and do something like the true wrench turners around here.
in the motorcycle world we call people that spend more time talking and/or bragging about their cool gadgets parked in a lot and watching other people ride by "squids" while the real riders are out there on the road learning new stuff, figuring out ways to tweak what they have.

Agreed on the talking rather than doing though.
there are some really cool cats on here but most of them don't like to get caught up in all the semantics, they'd rather be in the garage or at the track letting their work do the talking
wanted to give the best example of this that i know of:
i blew two motors with a twin screw swap waaaay back in the day before the turbo build. i posted up my numbers that it was about 330whp on a race tune and in no way safe to be run daily. one of the vendors about a year later came up with the brilliant idea to do a twin screw swap, and i warned them about the outcome and what hp to expect, i guess they thought i was full of **** but they ended up with a $5k cost and an almost identical number to what i had. i think they were running a few psi less than i was though.
so many people on here have the capabilities to make their car fast, but instead of doing it themselves, they sit and wait for these unicorn parts to come around.

there were 2 other members here that had projects going as well, the quickest i got was 11.24 and the others were 11.17 and 11.7* the dude running 11.17 was running a smaller turbo than i was, but he sprayed the hell out of it and threw a rod through his block. don't know what happened after that.

it's not about what any of us were using, i was just addressing the fact that people can sit for months/years dreaming about super top secret parts or they can take what's already available and make their car fast.

Hopefully, this winter, i'll have everything set up the way I want for now, and can bring some really fun stuff out to the general population on here. I feel that I will be responsible for many arguements.

In my motorcycle crew, we call loud mouth ******** that talk big who have no clue, squids....
Don't insult me by trying to ring up bikes in this thread.
And for the record, my intake IS NOT FOR SALE! This is my own project. And with that said, I have a job like everyone else. I do this project in my spare time. So shut the **** up and troll some where else.

couldn't say it better
Yeah, I understand that completely, thats why I've always had one of the quickest Cobalts down here, I actually do things that others talk about, but my situation limits how much I can push the car, I am just now getting myself set up with another car to drive so I can start the real work on the Cobalt, and I plan to have some pretty interesting results, but like you said I try to do the **** before talking about it. Nobody really knows everything going on with my car, ever. Always in search of a better setup, whether it be making parts for myself or trying things that no-one else wants to believe.
Hopefully, this winter, i'll have everything set up the way I want for now, and can bring some really fun stuff out to the general population on here. I feel that I will be responsible for many arguements.

let me guess, you own a suzuki? when you graduate to the superbike world and run track days in group a come back and talk to me
I think it will be very interesting to see what the lsj could put out without the restrictions of the cylinder head and the intake manifold. The head from what I've read seems to be a real restriction. Both exhaust and intake could use a good port and polish. Fix that and the next biggest restriction aka the intake manifold and this supercharged setup might be able to make some power.
anyone sell a ported and polished cylinder head to go with this intake manifold when it comes out?
