Modifying a 2.4L Engine

[dfx866]

Hey, i was thinking about doing some modifications to my engine in my 96 GA. I was contemplating a new CAI, ECU Modification, and premium spark plugs to burn up all the gas and air that i've increased the flow of. Also maybe a Flowmaster 50 Series w/ some kind of tip. The only two things are that the engine is a small displacement 2.4L, and it has over 100,000 miles on it. Will installing these upgrades put to much stress on my motor? Also if you have a Flowmaster 50 Series on a 2.4L or similar tell me if it sounds like a "rice" car or not. Thanks ahead of time for the info.

Well the flowmast is not a straight through design. It has baffles and stuff in it beause it is made for a V-8. Some people have them on their 2.4's and like them. As far as the CAI I would go with induction dynamics. I have that intake and am very satisfied with it.

i put a 40 series on my fiance's 2.4 and i like the sound of it. the 50 is more quiet. the 40 is a 2 chamber and the 50 is a 3 chamber. if you've taken good care of your motor the mileage shouldn't be a big factor. my truck had about 175,xxx and i was still modding it for speed lol. but around 200,xxx i started taking all the speed goodies off. for plugs i think we've decided that the ac delco's that came in the motor from GM are the best bet. or maybe some of the NGK (iridiums i believe).

Recommendations: start with exhaust, then intake.

"chips" or ECU mods do not yield much in performance gains. There are better mods for the money.

Also, better spark plugs will NOT create a gain in performance. (unless your old ones are shot)

Flowmaster can sound raspy on the 2.4. It's still a decent choice, but look into straight-thru glass/steel packed mufflers, such as Borla, Dynomax, etc.

the flowmaster on emily's 2.4 is not anywhere near as raspy as SLP. at first it had a little bit of a rasp to it, but after a couple weeks it went away and its kind of a deeper sound now

Yea, SLP sounds awful on a 4 banger.

[VanishingImage]

yea i agree with the last two.Exhaust first. Our 2.4 are quick cars,i was very suprised with my 1/4 mile time after i stuck my AEM intake on and had my custom cat-back exhaust,went from mid 17's,pretty stock,to high to mid 16's with the things i got now.Still rather have the 3.8 SFI in it tho:D

check out www.quad4forums.com and view the faqs there are alot of mods you can do to your twin cam ;)

[dfx866]

so matts, the 40 series is louder than the 50, but which has a deeper lone? Also how long of a tip would i need, and i'm guessing it requires welding huh?

[jayhawk]

dfx866, check out the 2.4L section here...theres alot of great info if you want to go deep with the engine!

[dfx866]

yeah i ment "a deeper tone"

[dfx866]

by the way Goldfever, i was looking at the CAI from Induction Dynamics, but what I want to know is if the CAI be safe for winter driving? Wisconsin has that downside to it (for car driving at least).

[Goldfever]

Yeah well I cannot tell you anything from experiance about winter driving because I live in southern Louisiana, but Induction Dynamics has tested these intakes in Canada. I think I remember seeing something like that. If I am just making this up someone please correct me.

[matts]

i dont know on a 4 or 6 cylinder, but on a V8 the 50 usually has a more mellow, laid back tone to it. it has the distinct flowmaster sound to it, but not as....abundant as the 40 series :) help any? and yes, it requires welding

[Gamebay11]

No you are right they are from Canada, i am saving up to get one from them, but not too happy bout the 265 dollar pricetag, since they are from Canada

[Gamebay11]

and dfx866, what part of wisconsin are you from

[Xidion]

another person from WI geez.

[dfx866]

hey I'm located in central WI, a little outside the wausau area.

[Xidion]

nice nice.

[Gamebay11]

yeah thats kinda close to me about a couple hours drive, im from kenosha

[Xidion]

where ever that is lol

[azeniskid]

OFFTOPIC!

[Xidion]

^ 0o0o? now your off topic.

[azeniskid]

2.4's suck

[dfx866]

yeah they're obviously not like a V6, but it's what i've got, and it's all i've got. Looks to me like it's what u got too. lol! pretty damn funny, azeniskid look at the description of your car in the left sidebar. It says your car is a pontiac grandma se. just sounds funny, hope it's not an offtopic though, J/K!!! ;)

you're right. you can have SO much more fun with a 5.7

[azeniskid]

I'm a fan of displacements less tha 3.0L along w/ the words inline along w/ the number of cyl's.

I won't knock the 5.7L though.

2.3HO is the original GM 4cyl of power tho.

[Xidion]

^ Lets stay on topic now guys come on

[bavnuts88]

I got a Ractive intake system for my car. We have the same one, by the way. I got an extremely noticable increase in power, just not as much in gas mileage. Although, I hear that an Iceman is the way to go. A bit more, but I guess its worth it. Ractive isnt too bad either, Im satisfied.

[bavnuts88]

Sorry, wrong one

[ebay]

I had a weapon R intake for my car that was crap. So I scrapped it and made my own bad ass intake with a foam element filter. I have an ebay no name muffler. I am Looking forward to get the new Apexi muffler that has a valve that opens only when you get on it. I saw it in a mag think it comes out in may or april.

[krazysmurf]

Bosch Platinum plus 4 plugs did increase my spunk a little bit
As for exhaust for a 2.4 i would stick to a straight through design to avoid high pitched honda style brands, i own a psudo, which sounds pretty mean.

[azeniskid]

We'll never sound like a high pitched honda. Displacement does count for something... sound.
