Just finished up supercharging my second 2.4. Did this one a little different than the last but not by too much.

Currently runs about 11lbs of boost, not sure on HP numbers but she's quick.













Here's the mods List:

ZZP 3" Intake
LS4 Throttle Body / Adapter Plate
Ported M62 w/ 2.9 Pulley
Dual Pass Endplate + Option B
ZZP S3 Intercooler
42lb injectors
2.9 Pulley
ZZP 2.5" Exhaust
Vibrant Midlength Header w/ Catted Downpipe
Poly Tranny Mounts
Powell C.A.B.'s
PLX Wideband
Boost Guage
Aeroforce Interceptor
Stage 3 Clutch

Plans:

Thicker Headgasket
Ported and Polished Head
2.8 Pulley
Possibly Larger Intercooler

 

Dude you should do mine! :P Nice build. Are you concerned with the bottom end at all?

 

Not too concerned about the bottom end with the power the cars making right now. Going to be putting a thicker head gasket on to bring the compression ratio down a bit (since the ported and polished head is going to be going on later down the road). Going to make the car a little safer to drive in the long run.

The car runs strong and intake temps and engine temps are normal with virtually no knock. Running the tune a little conservative. Basically told my tuner I want the car to be fast, but i want to play it safe.

 

bump

 

You should still build mine... XD

 

holy **** dude you're still around how the hell you been?

 

Haha i've never quite fully left. This is cobalt #3. Two ss 2.4's and a 2.2 Daily driver at one point

 

haha damn lol you just stopped posting.. well good to see you back at it tell me did you follow your own how to, to re install everything lol

 

Lol if you were in Cali i could help you build it, but if you have questions feel free to ask. Been through the process of s/c'n the 2.4 a number of times. Not too much different with the 2.2's mainly the tuning

Mostly reading and watching classifieds lol

 

Maybe if you have some documents that would help me out on what parts to gather and any tips or tricks would be great

 

Here's the original Thread i made back in 07'

https://www.cobaltss.net/forums/how-...through-80620/

 

Have there been any updates since 07? I know they make the 6-8pin harness for the LSJ TB, but I thought some LE5's came with 8pin TBs?

 

Welcome back beck
Trevor has been keeping me updated

-s flit

 

i have an 06 LE5 and it has an 8 pin harness but the harness needs to be rewired to work properly. Its in the how to. The only thing i really did different with the new build was using the lsj OEM idler pulley and Tensioner pulley.

 

welcome back? I must say your sc build thread helped me through out my build on my other car.

 

Yeah Trevor has been tuning the beast. Its running nicely. Just a few tweaks to make here and there to polish out the tune.

glad it helped. funny to see the date on that, cant believe that was back in 07. Time flies.

 

Clean car!

 

He tryin to get me to come up there
I wanna see both your cars

 

wow back at it again.

 

And this would change the belt needed to a 5 rib instead of a cut, 4 rib, correct?

 

Looking good beck ..we need to do a photo shoot

 

nah you still have to run the 4 rib because the le5 alternator, crank and a/c are all 4 rib. Just put the belt on the inner most rib, leaving the outside rib empty.

Yeah that black and white will be sick. I'll get my girl to get her uber camera loaded up and we can find a good place to do a shoot.

 

I thought we had 5 ribs and we had to cut 1 rib off of the 6 rib belt? lol idk never really payed attention. but your how to did help me out on some stuff that I got stuck on. I didn't think you were on this forum anymore since your activity looked gone lol

 

No you're right. I just had a brain fart. everything applies to what i previous thread, but yes LSJ is 6, LE5 is 5. Any way you do it unless you swap every pulley you'll have to cut a rib from the LSJ belt.

 

beck! Whats going on man? Can't believe you're still on here and building another LE5! I moved to Los Angeles - where in Cali are you? I'm thinking about dumping the S/C and throwing a super 60 on there. Maybe it will blow up finally.
