Woo Hoo 2.4L DOHC

[Domesticated]

ok i went to the junkyard to pull the motor out of a dodge caravan. right before we got started i noticed a stratus sitting right next to it. pulled the hood and there was a 2.4L that was in pretty good shape. turns out there is no damage except i need a new oil pan. so as i get the motor pulled i notice how clean it is. turns out everything on the motor was brand new and the block was painted black. after i got the motor out and all the accessories off including the manifold i then noticed there is no carbon buildup period and the valves are brand new! its been fully rebuilt right before the car was wrapped around a pole. im going to pull the pan and rod caps and see how it looks. then im gonna pull the head gasket and check the cylinders. hopefully in the next two weeks i should be sitting around 170hp and 190lbs! woo hoo. and my car only weighs 2250!

Noice! Much easier then the caravan? :P

[Domesticated]

i didnt have to take the front of the car off, hood on the stratus is twice as big, but still same motor

[2.5i]

Is that engine pretty much plug and play?

[Papercut]

Shoot, it took you guys a while to get that out... ;)
What a day...

[Domesticated]

mods to swap the 2.4: 58psi fuel regulater 80$, passenger motor mount adapter 60$, shaved some metal off front motor mount, modified water hard lines, pt cruiser alternator brackets. swap number 2 and three coil pins on harness, drop injector pins down one rung, turn key! also need the underdrive pully i already have on the 2.0 along with the DOHC high rise hood, egr block off, tps and iac sensors on the 2.0. from a stock 2.4 to pulling the 2.0 prepping the 2.4 and dropping it in and turning the key, 16-20 hours, simple job

[95_EGMneon]

Clean lookin 2.4, how much did you pay for that?

[Domesticated]

$114. got it hot tanked yeterday and magged it tolday. i think it was free cause the guy at the shop told me to do it myself if i really wanted to learn how to machine a block i had to do it myself. the guy likes me and is letting me hang out around the shop and run some of the stuff.

[Stang]

luck must of been on your side to find an engine that clean

[Domesticated]

[silver_echo]

can't wait to see what it looks like when in the car...

[JetBlack]

I like your bedroom blast cabinet. Is the also a parts cleaner booth? :D

[Brian]

nice. What is the HP and TQ difference between the 2.0 and 2.4?

[gustav129]

Hahahahahaha! Great workshop you got there.

[Domesticated]

nice. What is the HP and TQ difference between the 2.0 and 2.4?

2.0 is 150hp @ 6500 and 130tq @ 4800
2.4 is 152hp @ 5200 and 165tq @ 4000

right now my 2.0 is hittin around 150hp @ 7200 and 135tq @ 5500 at the wheels. im putting my 2.0 cams in the 2.4 to raise the powerband more, plus all my hp upgrades for the 2.0 will directly transfer over to the 2.4. i also took the balance shaft assembly out of the 2.4. tests at neons.org show that it doesnt affect high end power, they just reduce noise and rob power. and im doing a lot of headwork so the numbers should be a little higher

[Domesticated]

nope, i can pretty much just walk into the mahine shop and hottank my shizzit

sounds like a nice swap.

[Domesticated]

im gonna love the torque, im hoping to get my 2.4 to pull power to about 7500. ill probably get a set of cams for it. but bringing my powerband higher up will really make a huge power increase

[Brian]

i love the torque of my H22.

I'm not sure if this applies to the Neons, but make sure your axles are rated to handle the torque increase

[Domesticated]

im pretty sure im good. i know i could probably use some new ones but i know stock axles have got neons into the 10s before. not that those guys didnt blow a bunch of them, but they can hold up. theyre about 1.25" inch thick i think.

[Domesticated]

blocks pretty much done, all i need is a pt water neck and crank pulley

ports after dremel, need to polish them out now
http://i357.photobucket.com/albums/oo20/joncot1812/100_0002.jpg

[Domesticated]

just ordered the last of my parts, so now all that left to do is finish the head. i dont have any fancy tools so the polishing needs to be done by finger and sand paper :-(

"Old school" is now translated as "pain in the finger and takes forever".

If you have an air compressor, you can polish your intake as well. It takes all day but you get big hp gains, supposedly.

[Domesticated]

well im dont with all the ports, now all i gotta do is polish the combustion chambers and finish my intake. im just polishing as far in as the dremel and my fingers can reach :-(

[silver_echo]

hope you get done soon so you can save money on oil(unless you count actually needing to do oil changes)

[95_EGMneon]

can't wait to see the finished product and some videos of you smokin some Hondas!

[JetBlack]

Take it easy for a while after she's on the road :) You want to find the problems before you are at WOT.

:cry:

[gustav129]

Awesome! Can't wait to see it.

[Domesticated]

i pulled my motor and tranny a couple days after the leakage and replaced the rear main, no more oil leak

[Brian]

rear main seals suck to replace.

[Domesticated]

all i had was two jack stands a jack and my tool box in a driveway, luckily my motor stayed up with a jack under itand one motor mount. also luckily my tranny weighs 70 pounds really light and easy to work with. but my cast iron block aint so light though, it weighs probably three times as much as an f22

[2fast4usteeley]

comparing mine and yours at the machine shop it did seem like mine weighed 3 times less
And when you were doing your rear main seal i couldnt help but laugh a little because your all into the weight reduction thing quote from jonboy as he is under the engine"Hey guys, there is alot of stuff under here i dont need" (josh) "he could use to lose those few kilograms (laughing)

[Domesticated]

haha whatever

[gotrice93]

he said his little sisters mom gave him shit about having the tranny out say something about it being less weight with out it so he mise well leave it out

[2fast4usteeley]

leave the transmission out...lol
YouTube - This is why Mechanic love to deal with Women...
(it gets to a part where she thinks that the car has no transmission at 2:11)

[Brian]

^:lol:

Surprised he didn't have her get some blinker fluid too

[2fast4usteeley]

"halogen or regular" its really a question of quality.....lol

[Domesticated]

intake and exhaust mani studs in. arp head studs on the way!

[Domesticated]

well i finally got a valve spring compressor and finished the motor. i was timing it and turnin the motor over on the stand when i heard a hissing. my valves were the only thing i didnt touch in the whole build cause they were pretty much new. well in the months of sitting, they have built up a good layer of rust where they seat. kinda pissed. so now i have to tear it down again and im just gonna have a valve job done anyway. this is just getting iritating

[Domesticated]

you take this:

i forgot to take the pic with the belt cover and shiny aluminum mount on it, but youll see it when i do the swap write up im almost done!

[Brian]

nice man.

Gotta love parts that can interchange with other bigger engines

[Domesticated]

yea, everything outside the block is interchangable, same head even, and piston bore. i would have liked to grab a set of 9.8cr pistons out of an sohc, but i guess my 8.8's will hold giggle juice better. and the only reason i have to do any wiring is cause the crank trigger is 180* off. but thats literally five min of wiring. its gonna ba as easy as pullin my motor, swaping all the parts over to the new one, and puttin it back in. no modification at all

[Brian]

that is what I like about Honda so much. So much shit is interchangeable.

[Domesticated]

lol, my options are limited. bolt in is either a sohc, dohc 2.0 of only one style. or a 2.4 dohc. the srt 2.4 wont bolt in, only advantage is it has oil jets to cool the rods and pistons, and the head fits the turbofold perfect. can and has been done but wiring is nearly impossible to get oem gauges to work. but luckily everything but the crank can come off an srt 2.4 and be put on a stratus 2.4, including the 8.0cr forged pistons and rods. 500hp oem ftw

[shsking11]

I see a 1g dsm in the back there.

Does that have any realtionship to the 2.4l 4g64?

[Domesticated]

See a dsm where? and no, not completely, the 4G64 is 86.5 x 100, my EDZ is 87.5 x 101. i havent looked too much into them but im pretty sure its the same relationship as the 2.0's, D4RE and the 420A

[gotrice93]

i think he was talking about where your pulling the motor john boy. next to the stratus looks like an old eclipse

[Domesticated]

oh that was at pull and save, it was just a 1G laser

[Domesticated]

my new intake manifold, came in today!
http://www.modernperformance.com/indy-intake-manifold-9505-dodge-neon-p-1347.html
oh yea, i piad nothing for it and its been sanded and repainted

[Domesticated]

well its coming along. i am so happy i got a killer deal on this intake. itl kill a little torque but help my high end quite a bit and make a dramatic improvement when i boost. and i dont know about you other guys, but this motor hits max torque at 2500 and carries it to 6000 with these cams, thats a pretty hefty powerband!

sorry i didnt get a better pic of the motor, but you get the idea.
http://i357.photobucket.com/albums/oo20/joncot1812/IMG00353.jpg

[Iopni]

dang this sorta reminds me of a poor mans srt4 build lol. nice build i havent seen something like this since the 90's when thease cars were awesome track cars.

[Domesticated]

still are awsome track cars, for neons a first gen with a stratus motor srt converted is the best performance you can get outta any of the neons or srt-4.

[Domesticated]

well i got the motor in, took about 10 hours and a couple cases of beer ;-) the only problem i ran into was that piece of shit intake manifold. i wish i had gone with a stocker. nothing fit on my indy intake correctly. i have to get new bolts for my tb, had to reroute my cooland hoses "PITA". its a bitch just to bolt on. and the sensors are next to impossible to get on. had to modify the fuel rail. it started up with a flick of the key. something is wrong though, my ingnition timing is off and its running like crap. its a little faster than before i think, but i dies if i hit the throttle too quick, its having a hard time climbing and it slows down quick, dropping below idle before it levels out. im hoping i can fix it by adjusting the cam magnet. ill dyno it and then start making adjustments. ill get pics as soon as i can

[Domesticated]

well ive been too busy/lazy to work on it at all. but i got some new goodies that are probably gonna go on this next week. new ALUMINUM baffled oil pan. levi thanks for tryin to weld the old one, but it just didnt work. and my new cam gears!! these weigh as much as the tru times, but are stronger!!!
