I was wondering if our 2.4L reacts to mods (I,H,E, Cams, pullies) well in general. i know some 2.4s may respond to the mods more than others but if you were to put it in general. althought a k20 is diffrenent than a LD9, ive heard those motors respond well to mods. how does the 2.4 fair?
sorry if i sound stupid or dumb.
They respond alright but responding to modifications sometimes comes down to how the computer reacts as well, not just the motor.
With basic bolt ons, it reacts like how alot 4 cylinders would (atleast DOHC motors). Also, it depends on what parts you use, what size exhaust you get and a bunch of other things that come into play as to how they "respond".
Don't worry, your question isn't dumb. It's better to ask than assume.

hey, im new to this site, and was wondering if you tell me how well (or not well) 4 cylinders respond to bolt ons?..thanks!
is that not the same question?? lol

Most things respond well and make some noise but, you are not going to make lots of power with simple bolt ons. As NJHK said, it depends on what you get, what size certin things are, ect...

the LD9 responds much better than the LN2 I'll say that for sure lol

After reading around in an RSX forum, someone said that a car's reaction to a mod is also dependant on if the car in stock form is "suffocated". By this, they mean that it has a restictive intake or/and restrictive exhaust. they said it explains why some cars like the Type-R dont really respond to mods because they are basically tweaked in stock form.
to me it sounds logical but could this just be some ricer theory?

A big part of it has to do with the computer. Some computers, when they detect a higher flow of air or exhaust flow, they can throw more fuel or retard timing which can effect your powerband completely. Heck, try and turbo a car on a stock computer and it won't know what to do cause it's not used to seeing such a high rate of airflow...that's why people get Standalones/Piggybacks, Fuel Injectors, Fuel Pumps etc to supply enough fuel and the right amount of fuel...that's where "tuning" comes in
But back on topic, there are some computers where no matter what kind of upgrade you do, your computer wants to put your back to it's stock A/F ratio or very damn near close, so in reality, you upgraded your air intake amount & air flow but your computer isn't putting the right amount of fuel to support the extra air or ignition timing.
I hope this made sense...it's 4 am lol

Does the 2.4 respond well to mods. Yes. I have one (couple) my all motor car runs 14's.
As stated it does depend on what mods, size etc you do. Many people on this site will tell you many things. Just do plenty of research, do lots of reading. Look at cars with good times and what they have. Also remember just because you have the same mods do not mean you will be as fast. Driving is a BIG part!

soo..it does seem that computering plays a big part. since it seems that the 2.4 responds pretty well to mods (bolt ons), it seems the computer has a little "adaptability" to it. Right?
I also think i've found claims that the 2.4 respond well. on a neon forum and on the same rsx forum. On the street racing section, a cavalier was involved. they said they see Z's and have friends w/ Z's with bolt on running low 15's/ high 14's all day. twice, they also said Z's respond "disgustingly well to mods"

Thanks. Still have it. It is siting. We thought we spun a rod bearing, but might be a broken lifter, or valve spring. We will know soon. It will be better than everyone it is fixed.

nice nice... ever since i saw that car on ur site when i first joined i loved it... always wanted my 96 to be like that car... but i doubt i'll ever do half the things that car has... got any more pics of it?
I have a 99 2.4L M/Trans
2.25" cat-back
4-2-1 header w/ race pipe (no converter)
Short ram intake w/ K&N filter
62mm Throttle Body
Ported intake manifold
Upper motor mount
NGK Iridium Plugs
All of these are boltons... basic ones. I believe that my 2.4 has responded astoundingly well to each of them. My very first mod was the short ram intake, and even with the restrictive stock exhaust still there and everything else stock, the difference was like night and day. I love my 2.4 because everything I do to it, within reason, makes a great noticible difference. So even simple things cause a good reaction. Also, the only time my computer EVER gave me trouble was when I removed my catalytic converter, but that was fixed easily.
Of course that's just MY car. Just because we have the same motor doesn't necessarily mean that yours will respond just as well. However, I think it's a resonable assumption that yours will react nicely to bolt-ons as well.
Humm....I would say pretty responsive to mods.....it took great to the intake and exaust I dropped on it.........On the dyno it said that I had gained about 43 HP from just those two. Idk.......I'm looking for something more to do to my car, but don't really wanna spend much. I'm gonna sell it when I move to the mainland. What you guys think?

WTF?! No way... 43HP??? Are you absolutely sure?! I'm definitely not being a jerk here... but I seriously don't believe that for a second... not at all. There must be some mistake. Type-o perhaps?
Even if you did the COMPLETE intake (intake, TB, manifold) and COMPLETE exhaust (header, cat, cat-back) you'd be DAMN LUCKY to get +43HP (about 194HP @ flywheel) over stock on a Z, but you only have the Bomz intake and a cat-back... according to your profile. It would be more like +3-6 intake and +5-10 exhaust for you (+8-16HP, 158-166HP). I have FULL intake and FULL exhaust upgrades and there's no way I even have 43HP more from all that. All those numbers are relative estimations, of course.
Was this dyno a "butt dyno" perhaps?
You'd have to upload pics of Before & After dyno charts for anyone in the world to believe you got all that power... but I doubt you have them... because that power increase is basically impossible.

I have to raise the BS flag i have a lot more mods that you and i have a 992.4 and did not make 43 HP. The GM supercharger alone puts down something in that range from GM claims.

thanks for the input. I just had my header installed just today and I didnt really get to open it up untill i reseted the computer. Cant wait to open it up.
For those who have the LD9 and have mods, Put in your inputs and what you got to say after the mods u have installed. if you think it has reacted well or no diffrence.
I have a 97 2.4L and I have installed A short ram intake with a K&N filter and I noticed a difference in the higher speed acceleration. Pulled a little harder when I put the foot down. Can't wait to upgrade the exhaust too.
Mine has done alright with the mods that I've done to it.........

WAI, solid upper and lower engine mounts, high flow cat, rksport spark boots and inserts, @!#$ty tires and ran a 15.3 @ 88. Not bad considering i know ppl with stock 2.4 autos running 16 flats. We'll see what the HO mani and 59mm TB does to that when i get to the track again.

15.3 with an auto!..daymm. good job man. best i did was 15.4 w/ 5spd. never got to run it with the HO mani w/ header+full exhaust though. but boy oh boy does the car feel like an animal now. I must say the header and full exhaust gave me my most noticable gain.. too bad our only track closed due to an expired lease. sad thing is that there is no plans on making another track yet
