There's a member on here and on the G5Club.net that has a 2007 G5 GT 2.4L engine and he has a turbo. IIRC, he's making 270+WHP/270+WTQ with an auto. Not sure about the difference in engine builds though. Quick look at wiki shows this:
2006 2.4 L Ecotec LE5 I4 171 hp (128 kW) 163 lb·ft (221 N·m)
2007–2008 2.4 L Ecotec LE5 I4 173 hp (129 kW) 163 lb·ft (221 N·m)

Same engine, just increased in power.

 

^^^ they're the exact same engine, GM seems to (especially of late) shuffle around their hp numbers.

I think that info is a little out of date, THE current (and at least last three years' issue's of the GM Performance Parts Catalog says the following;

My brother has installed one on his '01 Cavalier, he loves it.
Incidentally he and I did the install in roughly a half hour, on the street infront of our house, after which he had the car towed to a dealer to get reflashed.

I actually briefly contemplated buying a (then) brand new Sunfire GT to install one of these on (when the kit was first announce), but in the end couldn't justify it for a marginal hp gain over my Grand Am (1991; Quad4HO-180hp);
A car that with little real work, I would be dumbfounded to find I make less than 200whp on right now... (it currently runs faster than several FWD cars rated over 200hp.)

Last time I got my brother to come to the track with his Z24, I was just marginally beating him... and that was before I did a couple more modifications to the GA...

@ OP congrats on the purchase;
I'd suggest you don't get loft hp expectations and just enjoy your "new" car

 

I remember when my brother weighed his 98 Z24 and it was in the 2630 pound range .... I've seen curb weight's online from 2580 to 2750 so it's debatable. My SS/TC weighted 2880 on the scale with 1/4 tank of gas.

 

I raced a z24 sport w/e cavalier (latest Gen) and pulled far on him, the older 2.4's were quite a bit less powerful.

 

I'm very happy with my 2.4. With full bolt ons and a tune the engine really opens up especially if your a auto.

 

if that post was in reference to me, please re-read my post, because I know that the LE5 should kill an LD9 - if it's in regaurds to rukkee's post (#13), he said "roughly" and acknowledged the hp difference...

FYI (and then some because I feel the need to post this info for CSS membership to know):

• 1988-1989/1993-1995 2.3L 'Quad4' (RPO: LD2) = 150hp
• 1989-1992 2.3L 'Quad4HO' (RPO: LG0) = 180hp
• 1990-1992 2.3L 'Quad4' (RPO: LD2) = 160hp
• 1990-1992 2.2L '2.2' (RPO:L42?) = 95hp
• 1991-1992 2.3L 'W41' (RPO: LG0+W41) = 190hp
• 1992-1993 2.2L '2.2' (RPO:L42?) = 110hp
• 1993 2.3L 'Quad4HO' (RPO: LG0) = 175hp
• 1993 2.3L 'W41' (RPO: LG0+W41) = 185hp
• 1994-1997 2.2L '2.2' (RPO:L42?) = 120hp
• 1994 2.3L 'Quad4HO' (RPO: LG0) = 170hp
• 1996-2002 2.4L 'Twin Cam' (RPO: LD9) = 150hp
• 1998-2002 2.2L '2200' (RPO:L42?) = 115hp
• 2002-2005 2.2L 'Ecotec' (RPO: L61 in J-body) = 140hp
• 2004-2007 2.0L 'Ecotec supercharged' (RPO: LSJ) = 205hp
• 2005-2006 2.2L 'Ecotec' (RPO: L61 in Cobalt) = 145hp
• 2006-2008 2.4L 'Ecotec VVT' (RPO: LE5 in Cobalt) = 171hp
• 2007-2008 2.2L 'Ecotec' (RPO: L61 in Cobalt) = 148hp
• 2007*-2010 2.0L 'turbocharged Ecotec' (RPO: LNF) = 260hp
• 2008.5**-2010 2.2L 'Ecotec VVT' (RPO: LAP) = 155hp

* = Solstice only in 2007; 2008.5 Cobalt availability (not mentioned in 2008 model year Cobalt literature)
** = although not mentioned in 2008 literature, I believe this engine replaced the 2008-L61, at the same time that both the LE5 was canceled, and LNF was introduced to the Cobalt line. I am pretty confident that a friend of mine has a 2008 LAP powered Cobalt LT. (but I have been wrong before )

ok, I think that's my "post" for the day

 

from the little I know about the LAP... I think this sums it up

LAP= Mini LE5

with that said im glad I got the LE5.

Now with that said I think you got the wrong hp rating in there under LE5 as its not a 2.2 either

 

your LE5 is listed as a 2.2 and 140hp

wow fail on my part. i typed it then walked away, came back and hit post. oops

 

^^^ whoops...

thanks, when typing that all out, I did some copy & pasting!
(I also make a couple other corrections)

@ CordiaDOHC;
I wouldn't exactly consider the LAP a "mini-LE5";
it's still 16hp short of LE5, while only being 7hp more than the L61 it replaced.

 

Its a vvt motor built on a gen 2 block. That 16hp is partly due in part to the reduced displacement.

Its closest to being a Mini LE5 than anything else.

 

ok, I see what you're getting at then.
I understood your post differently - I thought you were purely talking on a GM-DOHC-4cylinder-HP type of thing there...
I was contemplating on posting something... and now I wanna;

Regaurding horsepower, I'd like to post up the following, a compilation of GM-USA DOHC 4 cylinder engines

What I consider to be more revealing is the torque numbers as well as looking at where peak numbers are made;

GM's DOHC 4 cylinder motors;
(using peak/year published numbers I have; listed chronologically from first released to newest)
LD2 = 160hp @ 6200rpm / 155lb-ft @ 5200rpm
LG0 = 180hp @ 6200rpm / 160lb-ft @ 5200rpm
W41 = 190 hp @ 6800rpm / 160 lbs-ft @ 5200rpm
LD9 = 150hp @ 5600rpm / 155lb-ft @ 4000rpm
L61 = 148hp @ 5600rpm / 152lb-ft @ 4200rpm
LE5 = 171hp @ 5800rpm / 167lb-ft @ 4500rpm
LAP = 155hp @ 6100rpm / 150lb-ft @ 4900rpm

Stock for stock, the LE5 Cobalt is a really good match up against an LGO powered Pontiac Grand Am or Oldsmobile Calais (they're roughly the same size)...

Just by looking at those numbers you can speculate which engine should outperform the next, assuming similar platforms ect.

What's really funny is when one kid gets lippy and underestimates another GM stablemate;

LE5 is the 2.4L, not the 2.2L. I remember that because when I bought my G5, it was an 2007 model. I wanted the G5 GT because it had the 2.4L and a few extra horses. I test drove an 09 G5 GT that had the 2.2L LAP with an auto. IMO 2.2L L61 with 5 speed manual > 2.2L LAP with 4 speed auto. The LAP felt sluggish to me compared to L61, but that might have to do with having a different transmission.

 

I owned an LD9 Cavy... slow as molasses compared to my LE5. Almost feels like more than a 20 hp difference.

 

^ i had one too, i think the gearing wasnt tuned to the LD9 as well as these LE5s are.

 

umm, I corrected my post (I cannot edit someone elses quote of mine) roughly twelve hours before your post.



That extra is probably the torque ~ were they both the same transmission?
(five speed will normally make the engine feel better - I cannot recall if you're an auto or stick; typically an automatic will cause more parasitic drag on the engine ~ resulting in more power to the wheels of the manual transmission car.)

The funny thing is (and maybe this is just because there are "better" ecotec's to hot-rod), you can get 200whp even out of an LD9 ~ while the LE5 seems to be nearly maxed out in naturally aspirated form... (re: the 200 hp thread elsewhere here)

Here's a video of a couple locals;
one has an LE5/auto, the other has (iirc) an LAP/5spd;
iirc they essentially had the same mods; shorty header, and CAI ~ but I might be wrong.

YouTube - 2.2 VS 2.4.MP4

These guys are friends, and actually the following time they went out, the LAP barely beat the LE5 - but the LAP pulled the heavy 19's, and put on his original tires c/w winter rubber, and we puled the spare seats & what not out of his car...
I believe they both widdled down to roughly 16.1 by the end of this past summer...
