why can i never find much for the 2.4 performance wise?! its always for the 2.2 or 2.0?!?

I'd figure there would be waaayyy more performance mods for the 2.4 but like i said I keep coming up on 2.2 stuff!, how much of the 2.2 to 2.4 are interchangabe? I know intake and exhaust 2/4 are compatible but internals, computers etc?

 

You can get tuned.

Hoffa ( a member on here) had a 2.4 n/a that was pretty damn quick before he went to supercharge it.

Intake, header, exhaust. Start with the basics. Throw some suspension in your car so that it handles better, and you have a solid ride. Or boost it. the 2.4's have seen some really good numbers at low boost levels.

 

ok well Forced induction is last on my list because I just dont have the money right now, and I dont need insane HP, but I do want a tune eventually, so the best thing to do is start with Intake, header, exhaust and THEN get a tune with those bolted up?

 

Lol @ 250 hp being "insane".

Yes, the 2.4 is the red-headed stepchild of the Cobalt engines. The fact that it only was available during 3 of the Cobalt's 6 model years doesn't help at all, either. But the fact that the LE5 was also used in the Sky and Solstice base models is a big help.

The complexity of tuning the VVT tables and the relatively small population of LE5's on the marketplace simply means that the economics for offering a lot of performance options to the LE5 in particular doesn't add up. That said, just about everything that can be installed outside the confines of the long block are interchangeable (sometimes with a little bit of tweaking) between the L61, LAP, LE5, and LSJ so there are a lot of options out there if you look for them.

 

none of the internals are compatible between the 2.2 and 2.4L as far as I know. But you may want to check out the Solstice and Sky forums vendors some of them may sell internals for the LE5. If you find any send me a message I'll add them to the performance list.

 

i just wish we had CAMS!!!!!!

 

We do if you can trust JBP.

 

you have vvt, why bother??

cams don't even help the lsj.

cams are not a blanket magic mod. uggh.

 

header, downpipe, exhaust, intake and tune.

$1000 could get you to 170+ whp depending on who tunes it.

 

might as well just save the money and go f/i.... thats pretty low numbers.

 

sub'd for more info. on mods.

the 2.4L is 149-156 whp or something stock, so a grand and all this **** later will get you another 20 whp??? that doesnt sound right. Dude i talked to a bit ago, told me he tuned his stock 2.4l i believe and just that put him at 170+ whp

 

i have full exhaust, intake, Trifecta tune, but i'm auto and i dyno'd 164whp. but that was also before the tune so i don't know what i am currently at. it's just a waste of money IMO. i'm about to start selling all my performance stuff and just make it look nice and then buy a bike. no reason to make this car fast unless you F/I the car or spray it.

honestly i d/k too much about cars but just enough to get by. but when the 2.2s can break 200whp with cams and full bolts on it makes me want to get cams for my car. how can anyone say that cams aren't effective?

 

Actually the cams help a lot however only 1 or 2 people have done a camshaft swap on the LE5. G5Mike was the first to do it but ran into major problems with the valvetrain.

 

you know why he ran into issues? VVT.

 

because theyre not. our lift numbers are significantly limited and as such a cam will not help squeeze out as much power as it would on 90% of the other motors out there.

i dont know any 200whp L61's that only have bolt ons and cams btw...

 

i was about to say the same.

 

The lsj was only around for 3 years if you don't include 04. lnf will only be around for 3 years also.

 

well like i said i don't know much so i'll take yalls word on it. but what about the cavis? i know there are 200+ whp 2.4 all motor cavis out there. i understand they don't have the VVT but what makes them different or even the 2200/2.2 engines? they all have broken the 200 whp mark. why can't we with all motor?

i just don't understand how we can't break 200 whp on our ecotechs.

 

It's not no much that we can't, but nobody has done it.

and i seriously doubt that's with bolt on's and a tune. Probably higher compression forged bottom end and/or headwork.

 

depending on who you talk to and what you dyno on...

after getting full bolt-ons, i hit 157 whp w/out a tune (on mustang dyno). after intial tuning, i was at 168 (again on stang dyno), then we road tuned for another couple of hours. alas, i didn't go back to see what my final numbers were.

i said 170+ cuz it's going to be different depending on your tune. i've seen people with 170 after all that and people up in the 185 range.

imo, LE5's stock are low 140's. either that, or i just recieved a "monday" engine.

regardless... full bolt-ons and tune you should see anywhere between 170 - 185. period.


it's been done. i can't remember who on here, but it was done. and it took some work.

 

But was it on bolt on's with a tune +cams?

 

bolt on's, cam's tune + headwork (i think some pnp was done too)

everything minus f/i.

sorry, were you asking if 200 was hit on just the I/E/D/C and tune? then no... no frickin way in hell

it's been hit w/out f/i tho!

 

this, haha

 

the LNF will live past the cobalt you know....
besides, the market for a performance motor is always bigger than the base motor. The LSJ received love because it was the enthusiasts motor and had a lot of tuners own them. The L61 received love because it is in like 98% of the cobalts out there so even if only a small percentage of them wanted to mod, it was still a good sized market. The LE5 however, is an in-between. It is not the tuner motor, and it is no where near as common as the L61.
That being said, you can find anything for the LE5 that you can for the L61/LSJ excluding cams...so its not like you have zero options

this

the only person that comes to mind is alanoo (i think that was it anyway). He didnt even own a cobalt...we was putting it in an opel speedster and was from the UK

 

you're already wrong;
LNF:
2007-2009 Pontiac Solsitce GXP / Saturn Sky Redline
2008-2010 Chevrolet Cobalt SS / Chevrolet HHR SS
2011+ Buick Regal GS

so far 2007-2011 = 5 years



I don't think the LE5 is in red-headed step child category... instead of feeling sorry for yourselves why not look into older GM engines ~ aside from the chevy V8's, they have all (to one degree or another) been swept under the carpet - every single one

What I don't get is how people here (no offense Will) seem to think that changing cams will have negligible effect on HP;
after shortblock...
after cylinder head...
after intake...
after exhaust...
after tune...
what are you left with?

HINT: ideally all parts need to be matched & tuning isn't always the answer.
