ecotec engine vs a z24 engine

i am really concidering buying a new 03 ecotec engine, but i can't seem to find one. also which would be better a brand new ecotec engine or a used z24 engine. if i get the ecotec engine i was planning on putting in a turbo or a supercharger. which would be a better or cheaper way to go.

A USED 2.4l TWIN CAM WOULD BE THE WAY TO GO. IT HAS 150 HP AND CAN BE MODDED VERY EASILY. IT WILL ALSO BE ALOT CHEAPER.

where can i get a reasonably priced z24 engine with low miles.

Dont know, try searching around or get in the phone book. You might wanna even try E-Bay. If youre in the DFW area I know of a few places were you can find a used, low mileage Twin Cam for real cheap.

check any junk yards in your area. most charge by weight and the z24 engine isnt that heavy. and just on a side note the nhra cavalier has a ecotec engine and it does a 8 sec 1/4 mile easy

does the DFW area mean in dallas?

yes

If you can find one, the ecotec is probably a better choice. It is a much more refined engine and despite having 10 less horse than the 2.4, it is just as fast. The ecotec is an all aluminum chain-driven system and weighs only 300 lbs. I don't think that those 10 ponies from the 2.4 will be missed. I speak from personal experience because my last car was a 99 z24. Anyway, if you plan on doing mods it wont matter. Scrap yards are your best bet. There isn't too much on the net in terms of whole engines. Don't go to a u-pull-it scrap yard because those engines are usually stripped of all the goodies. I just bought a 3.1 for my 88Z24 that only had 40000 miles on it and that came out of a 1990. Front drive GM motors are a dime a dozen ( a great thing about owning an american car). The good thing is that regardless of what you choose, 2.2 ecotec, or 2.4, this engine is easy to find in a junk yard. This engine is shared in the Z24, grand am, alero, pontiac sunfire gt and probably a few others. It should be a piece of cake to find. Granted the 2.4 will be easier because it has been used for the past 6 years. Check out this link on the ecotec though. Maybe it will help you out:

i agree w/ mdb25 ^, the ecotec is a much better and faster engine. mods for the 2.4 and ecotec are the same--turbo, supercharger, nos, and many other bolt on parts; overall, the ecotec is the way to go.

stock motor vs. stock motor... I'm going to say the 2.4L is the faster engine... I'm just reading numbers though... ecotec is rated lower than the 2.4L


in the end though there's already a shitload of aftermarket support fo the ecotec and there's all that knowledge from dragracing it...

also there's all those destroked 2.0 ecotecs in europe running around... Eurospec anybody? hehehehee...

Ecotec would be the way to go in the end.. but right now that motor is a tad on the pricey side... wait until people crash a few of them..

until than pricewise you'll spend some $$ on both motors...

for the next year I'm putting my money on the 2.4L for buildability and ready parts..than I'll definately change my opinion to 2.2 eco... shortly thereafter...


however.. the 2.3 W41 would kick both motors asses... and it's ALMOST a swap into most any cavalier... just like a honda... wiring harness, motor, PCM, gauge cluster.. ;)

Yes, the 2.4 does have a little more hp and its a little torqier, but it weighs almost twice as much. Where do you see the gain? I wouldn't trust the numbers you read, they differ from magazine to magazine. Take it from me, I owned a 99Z with a 2.4 5speed and I now own a 02 LS sport with a 2.2 ecotec 5speed. The 99 is not faster. It roared a little bit more off the start and had a slightly torquier feel while the ecotec is very swift and much more silent. I'm not trying to turn this into a debate, but I know what I'm talking about because I have owned both engines. The 2.4 is definetely a sweet motor, but in comparison to the ecotec, it is more raucous and much heavier. The weight loss in the ecotec makes up for the 10 lost horse.

I agree that the ecotec would be better, if you have the funds. While I am a college student....I do not! I want to put the 2.4L in my 95 cavi. Right now I have the 2.2L w/ an automatic. I want a standard. Im trying to find some price quotes for a 2.4L, but theyre hard to find. I want a used engine though, cuz they produce a little more power than a newly molded engine. (they've been used a lot, so the block is relaxed and wont flex or move at all.) Does anybody know any price ranges, and/or any links or sites that I can find one? Junkyards are somewhat good, but they CAN also be bad because you dont know where they've been. Nothing is for-sure....people DO lie!!! Thank you for ANY and ALL help!


oh....my new cavalier site will be finished within the next few months!!! look for it: http//:www.hypercavi.com:bigthumb

oops! sorry about that last post.....my site doesnt have the :bigthumb extention at the end!:wink:

What is the 2.3L W41 engine from?? I've heard about it a couple of times. Is it a cavalier engine? Why is it so much better than the 2.4 and the ecotec?

the 2.3L engine is a bit of a rarity. only found in '95 cavaliers, the 2.3 dohc putts out 150 hp (same as 2.4L) but 5 lb/ft less torque than the 2.4 engine. since it is an uncommon engine, there is very few aftermarket parts avaliable for it. stick w/ the 2.4L, same performance, bigger aftermarket.

the w41 was extremely rare, it was a 190 hp and 180 tq, real beast of a 4 banger.

the regular 2.3 showed up in alot more than just the 95 z24, but they are all kinda hard to find.

the w41 engine featured in the j-body cars in 95, is 150 or so, the w41 in earlier years was considered a high output engine with 185 or 190 hp depending on what year it was, me personally, im going to be dropping a 190hp 2.3 in my sunfire in the near future and the ill be boosting that to about 8 maybe 10 psi

the 2/3l in the 95 is not the w41, it's the 2.3l lo

W41 was just a merchandising option from 91 through 93 for the H.O. Quad I think the engine RPO was LGO. They put them in Grand AMs but not the Cavys.

Ok, just a little fixing up here.
W41's were not used in Grand Ams, they were found in Oldsmobiles only
from 1990-1993. You find them in 90-91 442 Calais, 1992-93 Acheiva. If you did a lil research you would find the Quad 4 is an Olds engine not a pontiac or chevy engine. If you find one of these I will come to your house and kill you in your sleep for it. The W41 is basically the King Quad. I have driven them and like that old pontiac slogan goes "Driving Excitement"

Another point, the W41 cams you cannot just drop in a 95 Cav. The older style cams use a pulley to drive the power steering pump and the new 95+ style uses a gear to drive the ps pump. You would have to swap the whole head and ecu to use those cams and also you would need the ecu with memcal. you cannot use the HO memcal to run those cams.
(I have a 90 Beretta GTZ and am running W41 Grind 2 cams. They have a .240 lift versus .220 stock W41. And I cant even run with the stock W41 memcal. )

Same goes for the Old HO motors. running a turbo or sc in any High Output Quad is ludacrous. They have such high compression they would basically detonate themselves useless. Use the LO Quad w/HO Head and cams for boost...

I am also starting on an Ecotec project right now. I have a 2.2/5spd from an 02 Cav Z24. That I am putting into my 92 Beretta GTZ.
And I have also put a 3400 from an 00 Alero into my 96 Beretta Z26.

If you guys need anymore schooling from a girl let me know. I'll learn ya'.

I can also get all parts for swapping an HO Quad into your cav. from harness/ecu/motor/trans.

added: the rpo for W41 is W41, and the rpo for HO Quad is LGO...

i'm impressed. how old are u? can i marry u? lol

the eco-tec is an aluminum block???? jeez......now I want one too :bigthumb:

I'm 22 and taken sorry,

More added, the w41 is more than a slogan, its a different geared tranny still a 3.94 but with better 2nd, 3rd, and more aggressive 5th, higher duration cams, suspension, 140mph cluster, brakes (on the calais) basically a really sweet car.

And LGO may show up on a W41 car's rpo label because it does use an HO block, head, manifolds, A factory tuned HO Quad in a nutshell. Its basically the WS6 you may find on todays Trans Am's for those who still dont understand what I'm talking about.

Ok I agree with just about everything you said except for the last. The W41 was just a Olds merchandising option it is built off of the base LGO engine. The LGO is used in chevy, olds and pontiac.

Oh one other thing are you positive they were used in 90 calais? I don't have any listing for a W41 option cams for year 1990 only Years 91-94.
My information is directly from General Motors, but I really did not put much effort into research.

Opps didn't read all of your last post.

Agree completely... this was all I was getting at in my post about option codes and merchandising codes.

Eco All The Way

Hello to everyone!!! :smokin: :smokin: :smokin:
I am inquiring as to what it would take to retrofit a 2.2L Ecotec into a '94 Pontiac Sunbird LE sedan.
I have heard that I would have to change motor mounts, and I also know that I would have to have OBD-II-compliant electronics installed under the hood.
My main question is what modifications would I have to make to my fuel tank? I have heard that OBD-II powerplants are REALLY finicky when it comes to gas caps.
Any help and advice would be greatly appreciated!!!

althought the W41 is a rare motor you can pick one up for 3,000 from mantapart. Also just come more info the W41 was offered in only the 92-93 achivea SCX. You can find the HO inalot of cars, some nbodies had them and so did the berreta GTZ did to.

i got a 2.2 ecotec n i have had a 2.4 n the ecotec is just as fast as the 2.4 and it is a stronger motor

just posten some pics of my engine but, no its not for sale...
