My question is wich cavalier 4 cylinder takes boost best without internal mods. I know alot of people argue about this. I would like real facts. postem if ya gotem.
2.2l ohv
2.4l twincam
2.2l ecotec
if you can please post in order of strongest to weakest. thanks.
p.s. this could be a good reference for people wanting to boost.

like i said over msn, the 2.4 is strong er then the 202 ohv, the ecotec is the strongest of the 3 you listed.
parting out my built and boosted 97 z24 so4x4.com/cavy.html for pics and a parts list
and the 2.3 high output is the strongest of them all
Don't argue it... I kill people.....

i dont see why everyone says the 2.2L ecotec is the strongest, it hasnt proven itself over the other ones yet. The most anyone puts on stock internals is 10 PSI, maybe a bit more. And since ive been here ive seen more blown ecotecs than LD9s.

So far we've seen the Eco handle more boost, but we've seen the LD9 handle more spray. So you be the judge.

Where is the proof? We can not go by what GM has done, because that was GM, they can make the computers read everything, and anything they want, and since no one has done that with a 2.4, you can't fairly compare. I know of 2 ecotec's on the street that have pulled 15psi on stock internals and pulled good numbers at the track. Also know of many 2.4's that have pulled 15psi on stock internals as well. To date the LD9 has the best ET on boost. I'm not knocking either motor, but the ecotec has not been fully street tested on what it can handle. I know there is a lot of them out there boosted now, just a matter of people turning the boost up and seeing what happens.

I've been told 2.3 HO's are the best for stock internals and boost...
well theres more LD9 owners so of course alot of people will say LD9 this and LD9 that. I say the 2.4 and ecos are both great engines are fairly close in boost acceptance. I think why people think ecos accept boost very well is becuase there the only engine (between the all the ones listed above) comeing out of the factory boosted or supercharged from GM. But i think the 2.4 and ecos are equal taking in boost..as long as its tune properly. And thats from a eco owner =p
the eco was designed for boost was it not? all they did once boosted were lower compression pistons right? for the 2.0 eco in the ion redline and cobalt ss eh?
- JTR
the 2.0 and 2.2 ecos are not the same engines with different pistons...the 2.0 was designed for boost...the 2.2 was designed to be cheap, the 2.0 is much stronger.
2.0 Eco is best for boost.

wasn't there a sunbird and a skyhawk that were turbo'ed from the factory

thats correct....but those were 2.0 engines right? not one of the engines he listed at the beginning of the tread. but im not quite sure.
Thats why i wrote ...

that is true it isn't one of the ones listed
that was a 2.0 SOHC Opel engine...I would bet the 2.0 eco is the strongest, then the 2.4 eco, then maybe the 2.3 HO/W41 quad4

THE 2.0 ECOTEC HAS NOT BEEN TESTED!!!
We already know it can handle the boost that the charger is putting out simply because it comes bolted to it. Who has upped the boost on one yet though? Who has tried turbocharging it and making MORE horsepower?
The 2.2 ecos and 2.4 twin cams are blowing up because people are pushing them. I haven't seen one 2.4 fail because of teh GM charger with the reflash and fuel mods or one 2.2 eco fail from moderate levels of boost.
Everyone saying the 2.0 eco is strongest motor is pulling a guess out their arse.
I'd say the stronger motor should be judged with how much horsepower can be made without it blowing. Boost pressure AND compression should be taken into factor.

I agree with you on this to a point. The 2.0 is the same motor GM uses in the racing program. It is actually a 2.2 destroked to a 2.0, which is where GM got the idea of putting it in with a charger.
You are right people assume ti is the best because it has forged internals. It should be, but does not mean it will be.
Yeah there has been plenty of 2.4's blown from boost. We have also seen a few Ecotecs blow up from boost as well. Not as many because not as many boosted ecotecs, for as long as there has been boosted 2.4. We have only seen about 2 boosted ecotecs getting even close to what some of the boosted 2.4's have done. Does that make the 2.4 better No not really.
I will say this because fo what GM has done with racing the Ecotec they have created a bigger (or will be bigger) aftermarket for them, allowing them to exceed the Quad's. Still does not make them better, or worse.

Come on. Destroked, lower compression, forged internals, oil squirters for the piston undersides. None of the other J engines had all that plus 4 valves per cylinder. It's really a no brainer. It should be a rock. I don't care if it is "untested" the parts list looks alot more impressive for a boosted car.

^^^^When you're dealing with something that spins at 7,000+ rotations per minute, a parts list means nothing compaired to use and abuse. By all means, it should be a stronger motor for boost because it was built with boost in mind and they set up everything to take boost, but still, they only set it up to take so much from the factory. They need a certain amount JUST to make up for the power lost by decreasing the compression. Look at how much power people are putting down by upgrading the turbos on 4g63 DSMs without doing internals. It's impressive. If I saw a few 2.0 ecotecs pushing more boost and throwing down great numbers with the OEM forged internals, I'd be a believer.
I can completely agree with you though that it SHOULD be the better motor to handle boost. Is it going to be the highest powered boosted motor? I don't know any more than anybody else on the site.

I never said it would be the highest powered, but looking at GM's race cars, it surely has the potential, given the fact that the stock block is still in use in that car. But I'm willing to bet that it'll be the most reliable under boost.

seriously --- they already have a turbo version of the motor also that has either 220 or 240 hp stock (I forgot) -- i def think it would easily handle boost the best without question.
I respect all of the motors on this site but really there is not even an argument here
The strongest motor is the one that doesn't blow up and kill everyone.
Read, then process the info, think logically, than if you don't have a headache afterwards, post your response
