275 Horsepower Eco-tec 2.2

:banghead: I have a 2003 Cavalier and would like to get about 275 horsepower out of it. I was just wondering if anyone could inform me on how to do so.

wish in one hand, and shit in the other.....

If they make a turbo for it then that, intake, full exhaust, Headers if the eco-tecs have em..... NOS..if ya want...but i'd say drop a 2.4 Z engine in and go that way.

I don't want to do an engine swap...besides I've heard that the 2.4 aren't as fast as the 2.2 eco-tec stock.I'm pretty sure there's a turbo but i really don't know what to go with.

Who ever you heard that from is an idiot and doesn't know jack shit.

Do you happen to know the HP to weight for each engine???But like i said i really don't want to swap engines, because this is kinda a side project to see what a four-banger can do.I saw that GM had an eco-tec up to 1000hp, so i know that 275 isn't out of reach.

Can a stock 2.2 get into high 15's like a 2.4 can, no. So don't try to argue.

I wasn't argueing i was asking a question. I'm trying to build a four-banger and was trying to find out how to from someone who might know.I don't know much about them, the only custom car i've built is a '68 stang 351w 618 horsepower. I honestly just need help with the eco-tec if you know anything please.

Wish in one hand and shit in the other, lol. I asked my dad to borrow a $100.00 when I was 10 to buy something stupid, he said spit in one hand and shit the other and see which one fills up faster. I asked him if that meant yes or no and he just walked away.

turbo kit the thing with some rods and pistons and a lot of boost and you will get there. the 2.4 is a good motor but out dated. OLD, the echo is a better engine all the way around. my car is as quick as and stock 2.4 if not quicker. but then again i have been told i have a factory freak:evillol:

No that's just your imagination.

no ecotec is as quick as a stock 2.4L, ive driven them both and it just isnt the same.

I didn't want to start a fight over which is the better engine, honestly i don't care, all i wanted to know is how to build a fast eco-tec.Thanks for the tips so far.

Give you all quick specs incase your wonder. The 2.2L Echotec is 140hp, 150tq. The 2.4L Z engine is 150hp and 150tq. Now as far as weight between the 2 i cant tell you. But 2.4 being bigger, i assume is more weight, although it could be a nice light weight design engine. But turbo it, rebuild internals, and your good to go probably. I dunno about that much hp though.

Oh when will it end... If you wanted a 275HP Car, you wouldnt have bought a Cav.

The only way to hit that kind of HP is to run a turbo setup with a completely rebuilt motor. good luck with that. What GM does has nothing to do with anything... they have unlimited $$$

2.4L is 155 tq. . .

personally im not sure how you can do it but if you pick up the
new august issue of hci they are covering the cavalier and the
sunfires they have a 265 horse power supercharged 2.2 ecotec
on the cover but that set up probably cost some cash but they
have a buyers guide and tons of info on the 2.2 and i think some
on the 2.4

a stock ecotec 2.2 engine can run a 15 like the 2.4 and it has a turbo being made at www.exploitedracing.com and www.cavalierconnection.com
i think there are also a few superchargers out there too.

no ecotec is as quick as a stock 2.4L, ive driven them both and it just isnt the same.do you smoke crack frequently:screwy::p

Ok, your going to want to agressivly port the head, cams with more durations, higher compresstion pistons, new rods, lightened crank pully, intake, header and full exhuast, all new vales srpings and so on, probably cryotet some of the stock parts that are left like the crank head block even. or you can turbo it, or you can spray the shit out of it. think about what setup you want and i could probably help more.

You DO NOT want higher Comp Pistons if you are going to Turbo it.

my stock Z24 auto can run 15.8 1320. I doubt even your manual ecotec can do that.

Just for your alls info the reason they made a 2.2 ecotec was to replace the old 2.4L. Now if you compare a 2.2 and a 2.4 ecotec then they dont compare but the 2.2L ecotec are the same as the old 2.4L. Trust me we put them both on the dyno and they equal out.

why the hell would anyone trust you? youve made 3 post on this forum. . .

if you want a 4 banger with that power you would be better off getting a civic and set it up insted.
Cavaliers are slow anyways. put a stock civic and a stock Cavalier. the civic would smoke you

That # isn't to hard to reach with that engine. If it were me and I had some cash. I would rebuild the engine. Replace stock rods with some better ones, replace pistons as well, maybe evenlower compression. (depending on what it is stock.) You want around 8:1 comp. for a Forced induction engine. Cryo treat the crank. put some good sealing piston rings in. etc... I would do some major head work. an agressive porting, polishing. I would look into some better cams, something for a little more RPM. Then for the kicker, I would slap a turbo on that bad boy, and I think you should be really close to your target #.

One of the guys in J-BOM built his engine, has 350+ at the wheels, but he also put more into the car than it probably was initially wotrh. best deal would be a simple turbo set-up from Hahn, I think they are rated at 235 HP or so. Anything much bigger than that and you will need to do lots of internals and the like.

ok for one... stock 2.2 is 140 Hp 150tq at the wheels.. second of all.. Pontiac is comming out with a 2.2 ecotec Turbo for the pontiac witch will coincide with the chevy 2.2 ecotec (same engine) with it u will have 220 hp add some blow off valves adds additional 20-35 hp 240-255hp now ..and u havent even touched the Main Engine.. oh and the 2.4 is faster but not out of the gate:)

the Ecotec has 140 hp 150tq at the crank...NOT at the wheels.

show me a link that says Pontiac is going to release a turbo for the Ecotec. It just ain't gonna happen. Saab is the only company with a version of the Ecotec that has and probably ever will have a factory Ecotec turbo in the states.

add some blow off valves? :eek7:
you do know a blow off valve is nothing more than a release valve that releases unwanted pressure from the turbo right?

you can't add more than one!
20-35 hp? :cwm27:

:lol2: I don't like cavalier but that still make's me crack up, SI run high 15, cavy run high 15, Id rather have a domestic that's easier to work on then some shit box with "vtec y0".I have beat the snot out of a new SI with a loud intake and exhaust. funny thing is that he got me from the start but the evil eco makes power after4500rpm and mine makes that si look silly with that big can on the back of there. I even beat a guy i work with and his 02 STS and pissed him off big time. but that was close.

man your are stupid, whats with all the noobs comming here lately just blasting this forum with stupid shit? 140HP and 150TQ IS AT THE CRANK MORON. And you obviosly dont know what a BOV is. CAUSE BOV's DONT ADD HORSEPOWER! And you can only put ONE on. ALl a BOV does is release extra pressure when you take your foot off the gas so that the engine doesnt blow up. . .
The 2.4L beats the ecotec hands down. Not saying the ecotec is a bad engine, just not as fast.

yeah these noob claims and comments are getting old...FAST!

man your are stupid. :lol2:

this is the link where i found the Turbo for the Ecotec from pontiac..u should really do some Research b4 u speak.. u make ur self sound stupid everytime u talk

http://xtremega.com/forums/printthread.php?t=178

the long awaited turbo from pontiac

yeah thats the company Twistec who is gonna release a turbo for the ecotec...there are quite a few companys that sell em already. Thats not a Pontiac product like the GM supercharger.

so it looks like you are the one who didnt do the research before you spoke... :disappoin

you honestly think i sound stupid when you want to add multiple blow off vavles to a turbo charger, and that these BOVs are gonna add hp? And you also think the ecotec is 140HP at the wheels? Please shut the hell up. Go away you noob and learn something before you talk.

if you want a 4 banger with that power you would be better off getting a civic and set it up insted.
Cavaliers are slow anyways. put a stock civic and a stock Cavalier. the civic would smoke you


I am completely stock (well besides the fact that i had a muffler chopped off) and i have out ran many many civics.

ok i got the true answer, www.cavalierconnection.com. get about 3 grand saved up, buy the turbo, intercooler, and injectors, you will push 280hp apx i talked to the guy myself, u can run at 14 boost on the turbo with those modifications, and if u dont get new injectors u can still run 4 psi boost, because adding all that air wont do anything without the fuel, but there is your 280hp question, and u dont have to do any motor modifications, its the rout im going

Cavy motor won't hold 14PSI very long..

besides the fact about the faster of the two, your best bet to get that hp out is it is get a turbo from Twistec, and then all the other mods you can afford after that, headers, thermal research exasut, fuel regulater, weapon-r intake...stuff like that...good luck on it tho...I'm at about 200 right now with out the turbo...with that I'm sure I'd get to there

^^^ oh god another noob blasting. . . no way you can get to 200HP on a cay without No2 or a turbo/supercharger. . .

200hp just with bolt on's... :grinno:

list your mods please!!!

Karo is the only person I believe achieved 200hp at the wheels NA...but thats full internals, bolt on's, EVERYTHING!

Get the GM supercharger... because with a 4 banger engine, you will surely lose the engines reliability with all of those foreign parts... but 275 is not out of the question.

^^^ oh god another noob blasting. . . no way you can get to 200HP on a cay without No2 or a turbo/supercharger. . .hello gm made a 190hp quad 4 in a production car 200hp at the flywheel is not all that hard to do.

moron did you read what i wrote? WITHOUT!!!! err noobs

ok... who care abotu the fucking 2.4.... i own a 97 z24 and a 04 ecotech and the fucking ecotech rocks some shit... even when my step mom drives (and she really sucks at the whole manual thing)... anyways dood... how deep into the engine do you want to go? You can trubo it and run about 7 psi and get 200+ hp... then again you could get forged pistosns among other things and up the boost even higher... but i would recommend just turboing it with 7 psi...


and all of you saying that this 275 hp is out of the question.... think about it... if they are pulling 600 to 1000 hp out of these engines... why couldnt the average person get the 275? if you did full internals and then bolt ons with a turbo... 275 could be reached... in my opinion i would rather buy a $800 s10 and drop a 5.7 Liter in it and in total spent about $1200 and beat ur cavy... but that is just me....

moron did you read what i wrote? WITHOUT!!!! err noobshey i did not call you any names! i am sorry i was wrong when i read it i was tired sorry. Man you are up tight go out and get layed lol.

i just got layed last night, and on wednesday and on sunday, its called having a GF, you pretty much get it when ever you want. When was the last time you got layed?

my ecotec ran a 15.9 stock and a 15.5 with just a short ram. turbo systems are available for the ecotec on www.cavalierconnection.com

wow i just read this whole post and i cant beleave all the bullshit im hearing haha

first of all the 2.2 is a good engine it is slightly stronger engine for FI then the 2.4 but not by much people tend to forget that gm made 1000 +hp quad 4 engine as well

second i dont think alot of you understand the whole concept of wheel horse power, maybe you guys should read up on it

3rd who ever started this post if you want 275 hp the closest thing you gonna get to that is a hans turbo kit or exploited kit, the hans stage 2 is stated to make 235whp thats apx 270hp with a 5 speed


Havokdragon no offence but thats BS right there
there is know way in hell you go from 15.9 - 15.5 with a short ram whatever that may be assuming an intake

i know alot about these 2 engines ive taken apart quite a few of both and set some up with FI and others all out N/A but over all the 2.4 takes to mods better but will break first with stock internals, but the 2.2 has a better block if your looking to get shit loads of HP like 500-600 range, also the 2.2 interals are a little bit stronger then the 2.4's but not by some extreme amount

both great FI engine imo aslong as you dont mind spending lots of money to get the tranny and axles set up for large amounts of power

the axles and trannys are the week parts in these cars not the engines then engines will both take up to around 300hp (to the crank) before interals will break but the axles and tranny will break long before that

RSMRacing.com has supercharger kits for the Eco-Tec.

u should of waited and bought the SS Supercharged Colbalt like i am.

I don't want to do an engine swap...besides I've heard that the 2.4 aren't as fast as the 2.2 eco-tec stock.I'm pretty sure there's a turbo but i really don't know what to go with.
hahn racecraft .com 240 hp

Hey bud...i know what you mean u wanna go faster...what i did with mine i put better cams in it, full exhaust and a turbo kit, computer chip, whitch made a big diff., i have no dout that a cavalier can be fast, just last night with the mods i have done to mine i raced a 2002 mustang gt and i tore the shit out of it, i also have a 03 cobra svt whitch is all stock but my cav still cant keep up with it...lol...but one day it will...if u wanna see pics of the cav hit me up and i can give u sum good pointers...by the way ive figured out that there are alot of smart asses on here that dont know shit but like to talk alot of shit so dont mind then...lol...have a good one bud

Just go with a turbo set up there is no draw of power like a belt driven charger either way you go its gonna be around the same price

i also have a 03 cobra svt whitch is all stock but my cav still cant keep up with it...:bs:

My stock 02' Z24 did the quarter mile in 13.2. That's STOCK!
Also, i beat a corvette off the line.
As well, i have beaten many honda civics, and honda elements off the line.

There are 280hp, AT THE WHEELS!, on my stock z24.
no BS, i kid you not, seriously!

Just last night i drag raced a top fuel funny car, and LOST! but only by a couple of feet... He jumped the yellow... that cheating bastard.

Forget mods, go stock! :nutkick:

:grinyes:

a tiny 2.0L engine in the cobalt, when supercharged, will pump out 220 hp approximately....you could get that thing up to 275 i would imagine with a bit of work, why they didnt put a v6 in it i dont know...the 3800 series by buick plus a supercharger woulda been great...i imagine they lowered the size of the engine to keep cost down and so that they wouldnt have to upgrade every single piece of machinery in the car
