2.3L vs 2.4

[vtown661]

Probably a dumb question but what is the difference between the 2.3L engine and the 2.4L engine? I know the 2.4L engine is bored .1 more than the 2.3 but im just wondering what the advantages are for having a 2.3 and why would it be offered. It makes sense to bore each cylinder .1 over to make 2.4 but I can't understand why anyone would want the 2.3L. Is the 2.3L only for strokers? and if it is, why? As far as I know the 2.4L would offer more torque than the 2.3L so why settle for 2.3?

Thanks

a 2.4 is a 2.4 block, a 2.3 is a 2.4 crank in a 2.0 block, use the search and you will find most of the advantages and disadvantages that you are looking for

 

[vtown661]

what do you mean a 2.4 crank? how can a crankshaft be 2.4 Liters? Isnt it just a shaft? If you could explain in a little more depth that would be very helpful. thanks for the quick response though.

 

[inneedof]

the crank out of the 2.4 block

 

[vtown661]

Ok so what does this 2.4 crank do? why is it better than the 2.0 crank? Does it go down further or something? For both the 2.3L and 2.4L you bore the cylinders to those measurements right?

BTW I did search and nothing came up when I typed in 2.4L, 2.4, 2.3 vs 2.4, etc. Idk if the search engine doesnt recognize numbers or if its not working propperly or what. sorry if im asking stupid questions im just confused right now.

Not quite. By boring you increase the diameter of the cylinders. Thus allowing them to hold more volume and increase the size of the engine. 2.0, 2.3, 2.4 etc.

The point of building a stroker is to get more low end torque.

If you planning on doing any kind of project this big I would suggest learning a lot about it before you get your hands dirty.

No you do note bore the cylinders.

The crankshaft do the lifting of the pistons... so the 4G64 2.4l crankshaft lift more then the 4G63 2,0l crank.
so if you have the same bore with more lifting you got more volume, thats why the 4G64 crank makes 2.3l in a 4G63 2.0l engine.
(known as stroker kits)

And the 4G63 2.0l Crankshaft makes 2.1l in a 4G64 2,4l engine.
(known as destroker Kits)

But if you have no clue at all, why you will do such a thing.

Yes McFox, im aware of that im trying to figure out what inneedof was talking about when hes telling me that a 2.4L is a 2.0 head with a 2.4 crank in it. I thought it was a 2.0L head that was bored to 2.4L which I believe is what you are telling me. Stroker engines are where you make the piston go down farther to increase volume. I think this is what inneedof was talking about but I was just trying to make sure. And what is it called if you bore the 2.0L head to 2.4 and then use the 2.4 crank? Is that a 2.4L or would that be something more like a 2.5L?

What im getting is that you can increase the volume of your head by 1) boring it out .1L each cylinder (circumference) or 2) making a stroker by putting a 2.4 crankshaft in so the pistons go lower and this increases the volume.

 

[vtown661]

So c711 are you telling me that you never bore the cylinders? If so then why do people buy new pistons .2 over, etc? what does that mean? and if you can bore the cylinders this doesnt increase the volume and make it a 2.4L?

And I didnt say i was doing it i just want to know because im confused.

oh my god. you gies got it all wrong.

the distance the piston travels down from the cylinder head and the bore of the cylinders gives you leters.
A 2.3 L crank has the rod shafts on it off set so that when the crank rotates drawing the rod and piston down (stroke) it pulls it further away from the head. but when it rotates upwards is is shorter then when it pulled down so that the piston doesn't get pushed into the head.

thus that is why it is called a stroker.
i hope that makes scense. you get more volume in your cyliners because the stroke of the rod, piston and crank are increases.

 

[c711]

you use overbore pistons because the cyclinders are not so tight anymore (wont fit right and you lose compression) and use to be bored out a litte.

I just told you that you can not bore a 2.0l engine to 2.4l, thats not possibel.
You can not bore a head! What for? The head has nothing to du with the volume of the engine! Maybe you will take off a litte from the head to raise compression.

What to hell are you trying to do anyway?
It seems you dont know anything about engines.

Simply, the 4G63 is a 2.0 liter engine. The 2.4 liter is made larger by wider (bigger bore) cyclinders and a longer stroke from the crank. To get 2.3 liters from a 2.0 you use the 2.4 crank in the 2.0 and you have to over bore the cyclinder 0.020". This boring and crank give you the 2.3 liter. The term strocker comes from the use of the longer stroke crank from the 2.4. The 2.4 then will just give you a little more volume, 0.10 liter more.

 

[vtown661]

Ok so lets see if i have this right... If you take a normal 4G63t (2.0L) and put in a new 4G64 (2.4L) crank with normal 4G63t rods and after market stroker pistons (which are "shorter" to compensate for larger crank) and don't bore the cylinders at all, you have a basic 2.3L Stroker. And if you do bore the cylinders you still have a 2.3L stroker but just have a little bit more circumference that is so minimal it is not part of the equation. I'm assuming that most people bore the cylinders while doing the swap to help with compression because the engine is usually worn out but this has nothing to do with the volume it holds. I have heard varying things so I dont really know who to listen to but Im getting it slowly but surely. Anyone else (wisemen maybe) have any input?

Thanks to everyone so far i think this will help others as well as lots of people seem to be confused.

You are getting closer, you will have to bore the block 0.020" over to have 2.3L stroker.
