cobalt engine swap?
Monday, November 07, 2005 8:06 AM
has anyone ever heard of someone doing a engine swap out of a cobalt ss(the 2.4) into a cavalier, which for me would be a 99 z24 with the old 2.4 but the cobalt i was looking at has 171hp stock and doesnt redline till around 7k and i wanted to see if an engine swap out of a cobalt into my 99 z was possible. ne opinions would help.

thnx

It redlines at 6500 or 6450 just like the 2.2 eco.

just cause it has the same liter age doesnt mean its the same......they using oranges to make apple juice....doesnt work.

either keep the 2.4 twin cam
buy a cobalt w/ the 2.4 ecotec

or quit asking stupid questions
there are like 4 other posts about this.

not to be an ass but you should have learned from high school. To learn about stuff ya go to research it. if you dont find what you are looking for then it coudl be a number of things.

i dont think so. what i heard the 2.4 eco has sensors and what not that need to be wired up. probaly be better to swap in a 2.0 supercharged

I've commented on this before and there are plenty of threads about this...

Basically, no one around here has the 2.4 ECO in their J because

1. It's pretty damn new
2. It's an experimental swap

When I say experimental, I say that because no one really knows the step-by-step methods of putting it into our cars and what issues there could or might be.

In my opinion, Spending thousands of dollars to gain 20 HP over your motor stock isn't worth it. You could spend that money on a turbo kit and boost your 2.4 and gain much more power.

well i do know motor mounts are completly different so that being said you would have to change
1 motor mounts
2 wiring
3 gage cluster
4 tranny
5 motor
6 some new way to run the down pipe cause compairing the 2 cars i can see that there is no way its going to go through the stock area
7 fuel system
8 i think that you would even need to change your shifter cables
9 relocate the clucth fluid resivior

hmm cant think of anything off hand but i can go look in the morning

well to make a long story short my younger bro just picked up a recked cobalt ss that was hit really bad in the rear for 2000 so he is gonna swap it all out and put it in the cavi and i think if i bug him enough i can get him to do a write up on it (my little bro is a gm certified mechanic lol)

so cross your fingers lol


PPPSSSS!!!! MMMMMmmmMMM boost=yummy

to all those that are commenting on doin the 2.0 SC rather than the 2.4 eco.....

1. It has VVT
2. It has bigger displacement
3. if fitted with a SC like the 2.0 SC model it would blow the doors off it

i've already decided that when my motor goes i want to experiment with the 2.4 Eco....its far superiour to the 2.4 twin cam and the 2.2 eco. It wouldnt even make sense to waste the money on doin a 2.0 SC swap because the thing is an emarrasement of SC car....i mean the car doesnt even have that much balls...i rode in one

also why would a person with a 2.4 originally want to swap out a motor with less displacement and a SC when he can just slap a SC on his car and be faster

and for this reason, i hear the 2.4 eco has sensors and probes that need to be hooked up. specail ones because of the VVT.

thats not reall a good thing when you consider the 2.4 eco is from the same block the 2.2 eco is from. when people boost the 2.4 they might end up having problems, because of thinner cylinder walls.

ok well first of all snowman your an ass. one im still in high school. the motor thats in my cavy right now is blown so im gonna have to get a new one newayz. and i really dont want a 2.0 because honestly i think its called a z24 for a reason. IT HAS A 2.4L ENGINE. well with that said i was considering putting a s/c on it but my engine is blown and i just wanted to know if anyone has heard of it before. so snowman get ur head out of ur ass. and thnx everyone else for the help and i really dont mean to be rude but when people make smart ass remarks it kinda pisses me off. and another reason i like the 2.4 is because i can beat alot of these little ricers around here and all i have is an exhaust and a k&n air filter.

thnx

Actually, that's far from correct. The Z24 models have been around since the 2nd gens and your 2.4 motor or any 2.4 motor that came in a J-body was offered in the 3rd gens. I believe the 2nd gen Z24s were 3.1L V6 motors and even in 1995, the Z24s were 2.3L motors.

So with that explination, it doesn't matter what engine you put in your car.

I wouldn't say that it's the greatest motor to actually hook up 10 PSI of Supercharged Boost to...remember, the 2.4L ECOTECs are 10.5:1 compression, unless of course you're planning on ripping apart that motor to replace the internals.

Snowboardorgohome wrote:also why would a person with a 2.4 originally want to swap out a motor with less displacement and a SC when he can just slap a SC on his car and be faster


Well actually, you're talking about a motor with stronger internals (they are actually forged), and destroked ECOTECs (the 2.0s) have the capability to rev higher and would be a great motor to turbo.

Snowboardorgohome wrote:1. It has VVT


VVT is only as good as you can manipulate it. You would have to somehow find a way to play with it to actually gain power from it. The guys you see with the hondas that run 13s all motor, they manipulated their VVT to bring in more air.

manipulating is only lowering the point at which VVT kicks in....you just hate anything with VVT cause it reminds you of hondas which you hate

you act like the 2.4 ECO is made out of tin and the second you run boost it will blow up...what about ppl boosting 2.4s and 2200 without any motor work. Tune it right and dont push the boost too high and youll be fine

What are you talking about? That's actually something I DO like about Hondas and I wish we had them on our motors before this motor.
