I dont know much about 4 cyclinders but i say if you put a supercharger or a turbo on a 2.4 you should be able to waste a ss/sc. I dont know but i know in the V8 world more cubic inches you got the better off you are.

 

Intake, injector swap and tune, header, high flow DP, cat back, gasket port match the head and you'll be as fast as a SC Cobalt with the 2.4. I had my Cavi running 14.6's in a 1/4 mile with intake full exhaust and a ported head so I know damn well an engine with more displacement and bigger injectors and a tune should be at least as fast! My Cavi was a 5spd too so you may need to get a stall converter too.

2X it does become second nature.... I commute into Chicago, I went 5-10 miles last week in 45 minutes (bumper to bumper traffic). Just imagine how many times I pressed that clutch in and out... I don't even think about it any more... kinda like eating

get the stick..you'll be fine in a week and in less than a month, you wonder what an automatic is

 

i have a 2.4vvt ss with some mods and according to the numbers posted by their corresponding sites... i should be able to hang with an ss/sc

injen cai (5-8 increase??)
CA 4-1 header (12 increase)
XTC dp with cat (8-10 increase)
gmpp performance exhaust (12 increase)

since the 2.4 is rated 171 stock, according to the rated increase from each item, you should be up there with the ss/sc. now put ss/sc injectors and get a tune and you should be able to smoke a stock ss/sc.

of course... that assuming that the websites that post these numbers are correct

 

im not, the tuner was in texas all this week, i been waiting for him to come back

 

I have some questions. How hard is it to replace injectors, how much do they cost roughly, how much extra hp are you going to get, and what do they do to your fuel mileage?

Thanks,
A.J.

 

don't just slap on nitrous.


Get an intake and full exhaust, then get the Nitrous shot (at least a 50-shot) then get a clutch/ flywheel and drag radials, then a sweet dyno tune. probably $3,000 total. you'll be running 13's and saving yourself money

you can use stock ss s/c injectors.. (a huge upgrade from yours). buy them on here from a staged or better ss s/c owner.. but you will need a 2.2L injector harness. Don't know the HP gains on that.
with my stock injectors i got @8MPG.
now with the #42's i get 25.5MPG
you should be doing way better than that

 

Ok, why a 2.2L injector harness & where can I get one?

 

that's a truely un-educated response. you don't know how much money he will lose just buying the ss s/c

 

i seriously doubt that a 2.4 against the sc with equal horsepower will even be close. the horsepower will be the same but the torque wont.
the sc has much more torque than what gm says. and gm's hp rating is wrong too. its more than 200.

i would say as many bolt ons as POSSIBLE minus a turbo and some other stuff with a pcm tune on a 2.4 will probably have as much torque as the stock sc.

that means header/exhaust, intake, torque converter (if auto), upgraded clutch, lighter flywheel, the same or better performance tires, possibly engine mounts, the whole 9 yards and then the pcm tune with AT LEAST 42lb injectors if ur looking for big boost later on.

that supercharger adds quite a bit of horsepower and quite a bit of torque.

meaning that everything else is exactly the same, manual trans, 18 in wheels, performance suspension, any differences from the LSJ engine to the 2.4. the only differences would be the 2.4l displacement and the 2.0l with supercharger.

even the clutch is different on the 2.4 being less aggressive.

then we have a race.

dont even compare a 2.4 auto 4-door with the sc.
you'll just lose.

i think it would be cheaper to buy a sc and bore it out to a 2.4 or whatever u gotta do to get it a 2.4 and then slap on the stage 3 kit from intense or any other place thats not gm because the pcm tune is actually better if its aftermarket.

better than buying a 2.4, then swapping all parts from the lsj (including suspension and the upped first gear of the sc) which is more built despite the less displacement, and then buying a $3000 supercharger and upgrades.

these two trims are so different that i would consider them two completely different cars despite the similar body style.

2.4s arent meant to go fast. you'll spend more money making it similar to the sc, when u couldve just bought an sc to begin with.

2.4s can go fast if u slap on a big ass TT kit. someone on here has done it.
but for that much money an sc can just buy a whipple for less money and almost the same bang.

not to mention all of the parts that needed to be built up before the TT goes on.
the lsj can handle the whipple no problem. they were designed for massive boost operations.

i plan on buying a pontiac g5 GT 2.4 (pushing for manual <-- dad's being a jackass)
in the first and second year ill slowly but surely replace just about everything in the 2.4 prepping it for the TT or just one massive turbo.

 

cause thats the one that works, you're doin crazy custom injector swaps. and you get it at the parts counter..
don't know the price.. call your dealer monday
BTW, u cover shipping, i send my stock injectors for free. not needed anymore. 17,000mi on them
unless you are close to NJ... then just pick 'em up. I'll P.M. you my locale.

 

maybe not THAT much, but at least you'll blow out the stage 1 and stage 2 sc depending on what size pulley they want and what injectors they get.
im used to the stage 3 intense cobalt sc 2.5 in pulley w/pcm, header, exhaust, intake, and engine mounts.

i keep forgetting thats not stock anymore.

oh yeah get the 7000 rpm reflash if u didnt already know. it comes with pcm.


ah dammit i forgot to quote the guy that asked the question...
oh well.

 

Bro, i appreciate what you've done here, as far as time consumption... but this is incorrect. the 2.4 block will put down more torque.
the ss s/c suffers from parasitic loss due to the s/c running off the belt.. 245WHP/214WTQ... see?

you seem pretty knowledgeable for someone with 6 posts.

 

You could always strap a rocket to your ass. If nothing else you'll make the Darwin awards...

 

I started a thread about the injector and harness swap. You need the 2.0 SC injectors and the harness from a 2003 - 2005 Cavi or Sunfire. The 2.0 injectors plug right into the 2.2 ECO Cavi harness and then that injector harness plugs directly into your 2.4 SS main harness. That means no cutting and splicing! Its all plug and play. Now Steve has an AWESOME tune for the 2.4's that believe it or not knocks almost a full second off the 1/4 mile times of the 2.4.

A mildly modded 2.4 with the injector sawp/mod and Steve's tune puts the 2.4 AUTOMATIC SEDAN'S running a flat 15 second 1/4 mile. Gains for the 5spd are even better cause of the traction control no longer being an issue.

Add all the rest of the bolt on's, maybe port the head and you'll be running the same 1/4 mile as a stock 2.0.

 

And yes I know the supercharger takes away power, but only when the supercharger is not being applied.

if the 2.4 block puts down more torque then why doesnt gm use the 2.4 block for the supercharger?

why a 2.0 instead?

the 2.4 by the way only has 161 lb-ft of torque and the sc has 200 something according to gm. and you say that the 245/215 is the sc. so where are the numbers for the 2.4?

hmmm well we all know its less than that.

and there aint no frickin way a 2.4l is running 245 hp, or 215 torque stock.

i havent posted since i havent been here in god knows how long.
and it seems i am quite knowledgeable for someone with 7 posts now.

 

Easy the 2.0 is just a destroked 2.2 and it was out first. The 2.4's VVT is so far beyond the 2.0 SC's operating systems it took a little longer to get it right. Doubt me? The 2.0 SC has about 210 operating variables in its tables compaired to over 460 for the 2.4VVT.


Thats N/A not with a huge power adder like a blower slapped on to it!

Same can be said for the 2.0SC Cobalt's too, "there ain't no frickin way a 2.0SC is running 245 hp, or 215 torque stock."

IDK about that as you seem to have forgotten the oldest saying in hot roding, "There's no replacement for displacement."

 

So you're saying that if I put on the same mods that my friend has done on his sc i should be running faster than he does, assuming that i would put on the same exact m62 supercharger with configurations.


I was actually comparing stock for stock since no one in their right mind would take off the supercharger on their 2.0L and then compare because thats just retarded.


hey man those aren't MY numbers.
I don't even think my friend even gets that much hp with all his mods.

I actually read that before posting.
GM should've waited to get the 2.4 perfected before even releasing the sc or cobalts/ions for that matter.
well, they have it right, even in '06 so why don't they switch it?

 

i'm not saying they can put that # down stock... I'm saying he can do it for less than buying a 2.0 s/c, then modding it. and I would bet that he lays down a torque # closer to the HP # with the 2.4

 

For what engine the 2.2 or the 2.4? Now there are several people on J-Body.org that have installed the GMPP supercharger kit on their otherwise stock 2.2's and are making in the 240 whp range. One guy posts here but I forget his name, anyway he has a supercharged 2.2 automatic sedan that runs in the 13's with nothing more then the GM kit and a header with cat back. So if you were asking if a 2.2 set up like a 2.0 is faster then the answer is yes definently!

LMAO!!! Thats true cause then you be making like all of 90 - 100 hp!

Juuuust checking.

No point in switching it right now as the 2.0SC does a fine job as is and the 2.4 does also.
Besides if they stopped putting the 2.0 in the cars and replaced them with 2.4's then what would GM do with alllll those left over 100 hp 2.0 engines? Go karts maybe?


BTW superchargers always are "on" and they always suck hp to make hp.

 

hhhhhhhmmmmmmmmmmmmm tune is all i have left to do, i have 2.4 auto sedan, GMPP intake, exhaust, header, running 15.3 friday night. i need to get my ss/sc injetcors and tune, and 14.9 hear we come!

 

If your runing a 15.3 then with the tune and injector swap then YES you will hit 14.9 at least when you get it done!

 

(somewhat off topic)

for as knowledgeable as Insanecrazy07 seems he sure has alot of things mixed up...

according to a gm site (somewhere i found on google) the un SCed 2.0 runs about 140HP or so .. it's about equal on ratings to the 2.2 (due to the fact that as stated before it's merely just a destroked 2.2) however because of the extra displacement the 2.2 takes modding much better, as well as the 2.4. if you put a full exhaust on a 2.4 it'll help much more than a full exhaust will on the 2.0 ss/sc.

also if you notice the 2.4 and the 2.0 share many of the same forced internals, though they're not exactly the same gm made it so the 2.4 was no slouch and can handle some boost with a little work and a good tune. considering they already announced the end of production for the red line there was no reason to make the 2.0SS/sc or the red line use a a 2.4 even though it would blow the current ss/sc out of the water, it would've been a waste of money considering the 2.4l goes into many other applications.

Need I remind you that Hahn racecraft has a soltice at over 300HP on a STOCK 2.4?

i mean think about it... if I slapped a SC.... m62 or whatever i choose ( which wouldn't be the m62 due to the horrible efficiency of the blower due to heat) and I increase my horsepower 50.. which is about what the ss/scs get from the m62 (140*.50=70, 70+140=210) i would get approximately 255 CHP, which would be about 225 WHP and add into account that the ss/sc have basically a CAI stock that would make it so a 2.4l ss with a m62 blower would be pushing 30 more HP than you guys would be to the wheels.. ( so there is no replacement for displacement) and considering i paid 18 for my 2.4 ion QC and the redline was about 21 if it had all the same features. I can sc my car for just about the same price as i could buy a 2.0sc for however it'll perform much better.

(back on topic)

considering the 2.4 responds better to mods full exhaust, intake, injector swap, lowered ( for better launching) torque braces or bwoody engine mounts. and you'll keep up with stock ss/scs oh and you MUST have driver mod v10.0

for the record, the only 2.4s i've seen dynoed had 146whp and approximately the same torque ( i think it was like 140) on a mustang dyno so that number is probably closer to 155 or so whp. considering gm under rated many of their 2.0s I wouldn't be surprised if they underrated the 2.4s as well

so if you do said mods:

155WHP+15(full exhaust)+5(intake)+injector swap and tune ( which has been rumored to free up 15 HP or so)=190WHP I know that means the ss/sc will have 15 more HP from my estimated numbers however what the 2.4 lacks in HP it will make up in torque the red line as well as the SS/SC reach peak toque at around 4400RPM which means after that you're not gaining anything so when it reaches peak HP at 5600, where as the 2.4L peaks HP at 6200rpm and torque at 6000rpm

and with a 50 shot of "teh naws" that puts the 2.4 around stage 2 ( gm stage 2 of course) and the fortunate thing for you guys ... is you can do the header, exhaust and intake from GM and keep your warranty in tack.

a modded 2.4 can keep up with a stock 2.0ss/sc until the high speeds ( if the speed governor gets changed it might hold up better past 110 who knows) but really you don't get that fast on a 1/4 mile so you'll run with them.

why does it seem that people with ss/sc tend to think their car is uber? :rollseyes: and put down the other lines ( not all of them of course some of them are nice)

all that being said I'm no professional I don't work at saturn or chevy, and I don't think that the 2.4 is better than the ss/sc i'm; I'm just tired of people saying they should trade in their car to get the ss/sc if they wanted the power... some people want the ability to do it themselves, and have the extra CC to help them out.. then again some of the 2.4/2.2 owners ( like me) thought that the 170 would be more than enough considering my old car was 90 hp rated so yea... i think i'm done ranting...

just my .02

why can't you edit your posts? I just realized I made some spelling errors i'll probably get flamed for ...

regardless forced internals = forged in case anyone was curious hehe

 

How about an NA - SC analogy (I'm sure this is gonna **** some people off)


If I have a Hemi 'Cuda, and you buy a 440 6-pack 'Cuda, you can spend money and add mods until you're king-o-the-hill ... but you still ain't got a Hemi...

Partly the reason why I got the (smallest displacement) Cobalt offered, was the uniqueness of the whole factory SC package

And I'm sure that a high percentage (no, not all) of 2.2 & 2.4 owners would have got the SC if they could've (finances/availability/insurance factor/etc.)

FLAME ON!

(This post is all in good spirited fun, etc

 

haha it's ok... i could've bought the 2.0 sc... however like i said i thought i was gonna kill myself at 170 hp much less 205 I know many people probably steered clear from the ss/sc and redline for that reason... especially the extra 3K on the price tag... to be far though... the scion tcs supercharger is even worse than the m62 .... even though it's a centrifugal SC... it takes the car from 160->200 hp only a 25% increase in HP and 16% increase in torque... can we all agree thats extremely gehy lol

as far as the hemi comment though.. why wouldn't you get the hemi somehow it gets better gas mileage than the regular version lol

plus all ecotecs can put F/i on their cars so the only REAL uniqueness you have is if you bought a redline considering those are very limited edition now hehe

and though yes you got the factory sc package i just hope you know that when I get done with my procharger build i'll still own you on only 8lbs of boost hehe jk

FLAME ON!? wait you mean to tell me
