whats up all? i just ordered a 2.4 for my 95 avenger. I have been wondering about the intake. it doesn't look like it will hold boost well. so i started searching at first couldn't find any aftermarket intakes for the 2.4 , but i finaly found a link on a old srtforums post. i thought you guys might like to see it

WOW $650 I'll weld my own.

If you create your own, what makes a good custom intake as far as the inside of it?


*edit- that damn typo was getting on my nerves.*

I haven't done it, but that RX-7 you might remember, that guy did it.  To do it right, there are some serious calculations I guess.  If you're serious let me know and I'll ask him how to do it.

I know it takes serious r&d to build a good intake. even the guys who have been building intakes forever spend lots of time and money building intakes. like eldelbrock they have computer programs that design them and then they build them. i bet that they don't have many models that the build that are right the first ,second, third time and so on. building one you're self sounds a little defeating to me. you might be able to get to fit and look good but you may have little gain. yes 600 plus is very exspensive for a intake, but with over 30 hp and 20 tq  sounds damn good to me. i don't think i've ever heard of a intake with much gain on a 4 cyl. but hell if you can build it and get that kind of gain out and make it look as good than sign me up i' ll give you the 600 well when i'm not broke that is

LOL well that's the issue isn't it.

My buddy is a genius.  He put down 988 to the wheels with a bad wastegate.  We were hoping for 1200, but I guess it's back to the tuning.  His intake isn't the prettiest but it definitely does it's job.  And I'd have to see the dyno results of the intake to believe the claims.  And I'd want a guarantee that states if I don't get that kind of gains I get a full refund.

"30hp + 20trq gains."  well, the guy had a bundle of few mods to it which in combination with the intake produced those numbers, not just simple slap on of the intake.

just keep that in mind  ;)

i am assuming the reason you have some much gain is because it s a srt4 part, and the intake is set up for after market throttle bodies not the stockie. if you put that on a na 2.4 its prob more like 7 hp gain  ::)

I assume that you're going boosted, since you mentioned the intake doesn't look like it'd handle boost well. Must be getting a Stratus or minivan engine, w/ the plastic intake?

Why wouldn't you just use a SRT intake? unless you're pushing a lot of hp, you don't need a "custom" intake. There's plenty of 375-400+ hp SRT's running the stock intake.

yes stratus engine and the boost will come later. i like the intake rather than stock srt4 because of the obvious: gain and looks i have the 420a now and have the obx intake and i like they way it looks in car

I'm the only guy running a 2.4 of all of you would be me and only me and I'm back on the board after a 7-8 months hiatus

first you can't fit a stock 2.4 under your hood so stop looking for any external parts made for a 2.4 , NA or boosted
you don't drive a cloud cars, a neon, a pt cruiser, a caravan or a srt-4 you drive an avenger/sebring and nothing will fit
trust me on that one

Alain

alain! glad your back! how were your holidays? lol

anyhoo. you should link him Your engine  ;) give the guy some hope and a dream.

I have read the posts on asec by alain. Very cool and informitive.I havent started my swap yet because I am waiting for space to free up. I have to use brother in laws garage so i have to wait for him to finish his project first. I know that its not a direct fit but I want to try to use the 2.4 head befor i resort to my old 2.0 head.I dunno if it will work yet because I haven't even got my 2.0 out of the car my plan is to use a pt cruiser header and mod it to fit our exhaust and then use the stock2.4 intake. as far as the mount and the crossmember I have a cpl of ideas i want to try. befor i settle on anything.

I'm a big south park fan
in the first year of the show there was an episode called A Pig Make Love To An Elephant
and of course we see that ... textually
and Chef said after earing Carthman little pig screaming in pain " now I know how all those white women fell"

now imagine that the female pig vagina is your engine bay and your rear exhaust 2.4 engine is the elephant penis
but unlike the female pig vagina the engine bay can't stretch one single inch

then you realize that your "header" can't fit between the engine and the firewall because we don't have enought space
then you realize that the firewall doesn't have a big notch in it to make space for a downpipe unlike all the cars on the planet with a rear exhaust engine
after that you could figure out that the hood won't close because of the slope and it will touch the 2.4 engine intake manifold

just make yourself a favor throw the 2.4 head in the garbage where it belongs and keep the rockers and lifters if they are the newer ones
don't try to reinvent the wheel the wheel exist already and it is proven that it could roll

I told you guys that the bitch was back

Alain

PS: make sure your engine is not a 2003 an up btw  ::)

lol nice anology I remember that episode. I have been waiting for you come and burst my bubble. The motor i have is a 1997 out of the stratus. I thought that the displacement differance between the 2 motors was in the head. Is this not true is it in the stroke or in the bore? 
Pugsley

the stroke
the bore is the same
bolt pattern of the head and headgasket are the same too

Alain

cool i thought the head carried the displacement diff. I know its a tight fit back there  i have a obx intake on my 420a there is bearly enough room for the vacume lines on the back of the intake. the intake plenium is huge and with the runners it has to push it 6-8 in past the head. I figured if i could get that massive intake back there i wouldn't have a prob getting a header back there. when you swapped the head. you used the 2.o head and cams and the 2.4 lifters valves and springs?
Pugsley

alain since i got you interested do you think the moroso pan will give enough clearance for the dp and the crossmember?
I attached a pic of it.

don't buy the moroso pan there no place for a downpipe crossing under the pan and we need it that's a neon only part and on top of that the 2.4 doesn't share the same pan as the 2.0 there's no way to fit a 2.0 pan on a 2.4

I used a complete 2.0 head the 2.4 I bought was a short block with no head
and only a recent head 2.4 will have the good parts called the pt cruiser style rockers and lifters
an old one from 2000 and earlier will have the exact same parts as your 2.0

I.m pulling the engine this winter and rebuilding a few things including putting modified aem cam gears and crower 2/3 cams

a neon has 10 inch of clearance between the engine and the firewall, a cloud car has even more
both of them has huge exhaust tunnel while we have none
and if i remember correcly we have like 6 inch of clearance

Alain

FYI those who don't know:

Cloud Car = Breeze, Cirrus, etc.

lol go figure stratus clouds, cirrus clouds, breez caused by big ugly clouds.
any hey If i swap the head out should i use the 2.0 cams  or the 2.4 cams

you can't use 2.4 cams or neon cams

you need a COMPLETE 420a head
but you could cheat on the valve cover if you are creative and handy

Alain

You need a complete 420A head from an Avenger/Eclipse/Sebring/etc, not a Neon 420A head.

technically speaking neon don't have 420a !
they have the D4RE (dual 4 rear exhaust) or S4RE (single 4 rear exhaust) engines
don't tell any serious neon tuners that he owns a 420a

yupe the bitch is back !

Alain

I never knew that... Sweet!

Me either, good info. I've never seen anyone call them that though, even on the Neon forum, and since the OP here doesn't seem to know much about them, I was just trying to clarify for him that he can't use a Neon head.

i am the op and never even said anything about a neon head maybe you should read the thread again i was asking alian about the specifics of my 420 head going on my 2.4 motor . the only reason the word neon is in this post is because the pic of the oil pan i posted was for a neon
As far as not knowing about neons unfortunitly i do i have owend 4 of them so i def know the dif between the neon 420a and the avenger 420a but thanks for clearing it up for me
I hope i havent offended any neon owners with the 420a but thats what it is weather you like it or not ;D

they posted wrong picture of oil pan. they have it listed as early style 2.4 stratus pan but the pic is of a neon pan
http://www.howellautomotive.com/index.asp?PageAction=VIEWPROD&ProdID=766 ???

if you have a 1997 engine chances are you have a nice steel pan bolted to it
the best pan to modify without spending big $

Alain

yeah the pan i have is steel its big and ugly lol. problem is i don't have a welder or access to one nor am i any good at it I was just trying to find a easy out

easy way out is to measure everything several times and cut it with a 10,000 or more RPM grinder fitted with a cutting wheel
finish it with a sanding wheel
do the same time with 2 thin piece of flat fitted on the pan
bring that to a welder in the end

Alain

right on man i appreciate all the help. I have a bunch of poly bushings laying around that i bought for another car but never put them on . One of them fits in our mount  flanges so i planned to just jig up some pipeing and have it welded together to than press my bushings in . but i was planning on makeing two of them because if i send one to this guy i have been talking to on ebay he will make a sweet billet peice
I am also glad that i have to use my 420 head because i have a header and a obx intake for it I will need to get a bigger tb though maybe the 2.4 one is bit bigger
but thanks again i threw somw karma at ya

btw you should invest in a cheap 110V stick welding machine and learn to do simple welding joints

doing a 2.4 require some metal works and at least you will have the chance to make a custom part that can hold together strong enought so you could bring it to a professionnal welder

Alain

Ahh well my bad then  :) You were talking about using 2.4 heads and cams an I got confuzzled I guess  ;D
