Yes I've searched don't hound me Jesus

Okay from what I've gathered, the 2.4 shifts the power band up a bit, but creates a deadzone if it's not tuned; losing out on torque.

So if I'm fooling around in town/highway with civics will the 2.2 IM actually be better? Since most base model econo boxes are torque less.

I've read people running 1/4 prefer 2.2 over the 2.4, so what is the real benefit here?

This is all without a tb and tune


Thankkkkkkkz yo

 

The 2.2 manifold was designed with the 2.2 motor in mind. From what I've seen, if you're not upgrading the TB and tuning, there isn't enough of a difference to make it worth the time and effort of swapping it out. An intake and exhaust would yield noticeably better results than the 2.4 mani.

 

I've read the tb barely does anything, and tuning is only a small difference :s

Anyone that's made the switch chime in?

 

That was one of the first things I ended up doing. All it did is made a different noise and make like one more pony up top. After that you can just through some boost at it and it doesn't mind. Or if you really wanted to you could through a small shot of N2O at it, however I highly advise against that for the sake of longevity... But I've gotten ahead of my self again... Unless you plan on building in the future, the money is best spent elsewhere.

 

I remember this debate from when it first came out.

I did a calculation on horsepower over the entire range. There is the exact same power under the curve between the two manifolds. With that being said the 2.4 made more up to so if you are racing and the RPMs staying above about 3k rpm then you will be faster.

As for 2.4 TB. I felt a lot more throttle response, but not a lot of power.

Tune definetely helps if you have full intake, IM, TB, and full exhuast.

But price/performance is not there. You will spend the same on all of the mods and tune as about a basic supercharger setup. Well unless you get parts for extra cheap or used.

 

Yeah have any of you actually done a 2.4 manifold and throttle body on a 2.2 engine? I have. It is an excellent investment for the 2.2 if you don't plan to boost it. The manifold, tb, and an exhaust gave me 168whp on a 2.2 with a trifecta tune. That number probably could be around 175 with an HP tune. The power you gain will negate anything you might think you lose in the low end. If you just get a 2.4 manifold, by itself, isn't gonna be worth it. But then again, an intake isn't really worth it by itself unless you do all the bolt ons and tune it.

 

To elaborate on what dyldo (Love that screen name btw) said, from what I understand, the 2.4L is a slightly larger manifold. If you use a stock TB its only going to flow as much air as the TB allows in the manifold. At low RPM's its not going to pull air in any faster or flow air any more efficiently. That could be what you called the "dead spot" in the manifold. At higher RPM's the motor is sucking air in alot faster, making it a little better than stock, but only up high. But even then, its not necessarily flowing tons of extra air because the restriction thats now in the TB. So the only way to make it really worth the effort is to use the 2.4 TB as well. It allows the extra air into the mani and makes use of the larger runners/plenum or whatever the intake has inside.

At best, you may only see ~3-4 hp from the mod, but you'd see a shift in the power band slightly. I just dont think that its going to give you the results that you're looking for and your money could be better spent elsewhere, as has been said.

Im not trying to be a dick, just trying to explain why it doesn't do what you want it to do. As someone who was once where you are, looking to pull more HP out of an N/A motor, I used to always get kind of upset when people would tell me something was a bad idea but then not explain it. So I try, now, to explain things so people understand why we say it may not be the best idea.

 

The 2.4 mani was the last mod I've done to my car. I have an intake, the 2.4 mani, longtube header and lsj cat back. The header did way more then a 2.4 mani. Most if not all the difference I felt from the 2.4 mani swap was not at wot, it was furring daily driving.... I have a 2.4 tb in my trunk and will at some point out it on and tune the car but honestly, unless you get it for dirt cheap it's not worth it.

 

Don't think you can get tb without tune. Tune wakes the car up a lot if tuned for 91
