We are located in Toronto, Canada

We can trade injectors if we have someone who wants them.

We will not be porting the blower, but you can run a smaller pulley if you want more boost. Remember this was the stock 3.35" pulley of the 2.0L.

The G5 was a manual, but I don't see why it wouldn't work on a auto.

 

This is the first time I've heard of any of this. From everything I've read the 2.4 has a forged crand and rods, where did you find this info?

 

just to let u guys know Hahn got the 2.4 l up to 350 whp on the soltices on stock internal and the claim it s holding it without any problem
and for what my gm teck told me the motor built to take up to 400 did not specify whp or motor ....
and the rods on the 2.4 are forge

 

I can't say no to that and be 100% sure but this was a quote directly from the Ecotech LSJ Builders Guide.

All from the Ecotech LSJ Builders Guide located at GM Tunersource

 

2.4s FTW!!! i can't wait to see some angry 2.0s a TS would probably make 350 considering rebel's TS kit should make 300-350 whp on the lsj..hell the m62 would even have a shot at it since it's only running at 7.5psi and pushing 220 WHP... at 12 PSI it should push out around 270WHP or so. If you think about it it's pushing out as much HP with 3/4 of the psi as a stock ss/sc and some of those are pushing 280 the possibilities are endless. I'd like to see how much a 2.4 can take with the m62 until it breaks, just so i know that my build will be able to take more

I'm not necessarily looking to do this.. unless it's dirt cheap then what the hell why not haha.. however i'm ecstatic that some possibilities are coming out.

why would the lsj build guide talk about the 2.4?? i've read it before and never seen anything of that sort... and i've always heard that 90% of the of the lsj and 2.4 internals are the same... i actually had a site that compare the two o verify that as well... i'll see if i can find it...

regardless... from what i've spoke to with hahn their solstice is pushing 408 HP so thats good news

 

Damn can't make that drive and another problem is that my car is a 5spd HHR and the intake is diff then the cobalt's but i bet with minor work it could be done. Thats all thats diff

 

It is saying that the LSJ and LNF pistons are revised in re-enforced in the same key areas, but they are not the same pistons.

 

Its wrong. Here you go, just went to a GM website and found this...

2007 2.4l I4 VVT (LE5)

Heres the link.

Let me know if you can't find it. This BTW is in line with everything else I've read about the 2.4. Thats the first time I've ever seen anyone claim it has powered rods. They're just wrong is all.

The only difference according to this is the crackshaft in the 2.0 is forged and ours is cast. doesn't say anything about the pistons but thats common knowledge.

 

GM likes to be tricking about how it classifies rods lately.

Afterall, what exactly is "Sinter-Forged?"

just to put everything up next to eachother for comparison since you got to it before me

 

Thats cool I was wondering. Yeah it looks like the crank and pistons are the only difference. And a cast crank can hold TONS of power no problem, true forged is better but ours isn't exactly crap. Just glad that site was wrong about our rods being powdered like the 2.2 is. That was the first I'd seen any place say we had powdered rods so I knew it had to be wrong, I just wanted to be able to post some conformation to back me up.

 

hey rebel i was just curious of a couple things....if we could find those parts would you e wiling to just sell us the tune?....i would have better peace of mind if the parts were all brand new....how reliable is the tune?...how many miles have you gone on it so far and have you had any problems?and lastly could you please work up a price real quick so i can have an idea of what it would be before i cancel going with a custom turbo route....

 

glad we could be reconfirmed on this matter haha now lets go see if the dealers will warranty this kit +1 rep

 

So am I he scared me when he posted that! Yeah we could always say "but it an SS and blowers are stock on them what do you mean I voided my warrenty?"

Pretty sure that won't fly!

 

yea this route seems way better then the 4,000+ price tag on the turbo....if you look at the other ecotec supercharger kits they run 2,500 and i have no problem paying that for a bolt on kit ready to be installed in a couple hours....**** if i can pick up some used parts and get the kit for 1,500 i'll send my check now......

 

lol for you you'd be screwed, but I could get a redline badge and such and fortunately the body looks exactly the same haha so if i got it maybbe mine would be covered.. hell if it is covered and it's real cheap that might change everything I was thinking

 

Guys.... Hahn has already beat the 2.4 up on the Solstice. It is running 19psi making 330+whp. The 2.4 can handle a TwinScrew no problem. I dont know why you guys are saying you need to replace the internals to run it. I relaly wouldnt be surprised if you put down over 300whp with the same pulley size thats included in the 2.0 TwinScrew kit.

Also to clear something else up with the m62. STOP LOOKING AT PSI NUMBERS. 7.5psi on the 2.4 is still moving the same amount of CFM as 12psi on the 2.0. The roots charger builds pressure inside the manifold. Since your engine flows a lot differently, it wont build the same amount of pressure inside the manifold as the 2.0. What im saying is, you arent going to reach the 19 or 20psi mark on the m62. Your going to maybe make 14psi on a 2.5 pulley. Why? Because your still spinning the blower at the same speed as it was spinning on the 2.0 and making the same amount of CFM. Power is made by CFM, not Boost.

Though on a positive note, you will make less heat on the same size pulley because the blower isnt trying to cram as much air into the manifold. Which means more power.

Great job on puting this project together Rebel. Its about time someone shows the community its possible.

 

nice setup, will bring even more confusin about the ss/sc and ss/g5 to outsiders now

 

you know your ****!

 

could you tell us more about the tune?...i mostly interested in the tune and the price

 

Man, that's sick. I'd love to supercharge my 2.4 someday, but I'd still rather use a centifrugal supercharger like a Procharger. Someone needs to get that Speed Mafia Procharger kit for the 2.2 Ion and fab it up for a 2.4SS, tune it with HP Tuners, and then post the results up.

 

Price for a kit with all new parts:

alternator $351.98
Eaton M62 $1087
lower intake manifold $532
Cobra Heat Exchanger $200
Bosch IC Pump $80
fitting and piping $60
GM stage 2 belt $40
ribbed idler $30
intercooler surge tank $65
intake you can use the GMPP for the 2.4L or see below

parts we will fabricate:

additional idler with bracket $150
IC pump bracket $100
CAI for M62 $250

So a grand total of $2945.98US with all new parts

Tuning will be an extra $250US

 

Elecblue i believe is working towards doing that. If i had a 2.4 cobalt in my area willing to buy the parts, i would help them get the project done. I wouldnt mind lending my procharger to get it fabbed up once my car is finished.



guys, i would recommend buying the TS kit for the 2.0 and buy the lower intake manifold used or from GM and you would have 300+whp off the bat. The engine can easily handle it. It may cost you about 1k more,but you would have an extra 90-100whp and installation is the same.

 

well id have to say that that sounds pretty good for a supercharger kit....and i suppose we could get that stuff way cheaper if we were able to find a totaled ss/sc somewhere or something.....would you be able to go more in depth on the tuning?

 

That is a good price IMO for a 2.4l to go blown. Thats awesome.
