i need to rebuild my 97 2.4l 5 speed and need some advice as to how to build it i dont have alot of money i have about $3000 so turbo is no option so what compression and set up could i see good power gains for for under $3000 dollars i really wanted low compression and turbo but no money so i need a good N/A build i want about 200hp and if i need ill use a 35 or a 50 shot of nitrous
Thanks guys

for got to say my exsiting mods are.......
secret cams
ho intake manifold port matched
56mm t/b
lightend crank pulley
cold air intake
lightend flywheel
stage 2 clutch
ported head
header back exhaust in 2 1/4 upgrading to 2 1/2 with rebuild
and some good tires
First why do you need a rebuild? Is it broke, worn out?
For a N/A build and if this is going to be a daily driver I would do a factory rebuild (I did this on a 96 2.4 cost about $900, that was replacing all bearings, gaskets, oil pump, water pump, clutch, having head checked, new valve seals, block hot tanked, pistons checked, but reused stock piston, rods, and cams). With your current mods, shave the head a little to raise compression (or use a thinner head gasket), and buy HPTuners and have the car dyno tuned would be a nice daily driver N/A car, and still able to run 87 octane if you wanted.

i need a rebuild because all my pistons are scored dented and one has a hole in it. and because i have two cavalier z24s this would be more of a fun street car and my black auto z24 is my daily driver. i do not want a stock rebuild. and sense the car would be apart any way i might as well built it up. the pistons are dented and scored from being timed wrong. and yes i know i could just replace the pistons.
Thanks

Well knowing that then I would go with aftermarket rods,pistons, higher compression, built head (larger valves), header, intake, cams, motor mounts, tranny mounts, clutch flywheel, and HPTuners. Depending on if you or friends can do the building of the motor or not will depend on if you can do all of that with 3k or not.

2 of my uncles are mechanics and my grampa was a mechanic so with boring out .020 over and rod pistons rings bearings new head and gaskets,hp tuner and other parts do you think i could build it under 3k ???
you can get wiseco pistons and eagle rods for 700 bucks, if they can do all the work, you just need bearings, maybe even consider the 2.3 pump (150). that'll be 950. Get a cometic head gasket (for boost), ARP mains, turbo manifold, turbo, intercooler/piping, build your own exhaust, hpt, you would be right on the 3k mark. Provided you do all the work yourselves, :cheers

no way could you set up a reliable motor and turbo setup for 3000, probably even if you did the work yourself. Rebuild the motor using wiseco 9:1 pistons and Eagle H-beams, do the 2.3 pump swap, 086 head swap, (flows better stock than a 2.4's ported(info from the Quad master, MfK) That would put you somewhere around 11:1 compression. All new bearings, new rings, new timing kit, seal kit. Depending on how your cyl walls are, do a .020 over bore to get yourself started off on a clean plate. You could do that for under 3000, and have some nice power.
well the highest octane around here is 91 so i need a more suitable compression for 91 octane i dont want to use a 086 head to much work. so i need a compression suitable for 91 octane and to run a 50 shot of nitrous

it can be done, i've done junkyard 500dollar turbo setups that have out lasted factory ones.
imo if you want boost, go get a good low milage used engine (some wreckers even offer a warrenty, so grab one of them if you can) then build yourself a turbo system for it and run 6-10psi of boost.
it all depends on what you want to do, the one engine sitting here i have 3000 invested in the bottom end of the engine alone, thats not including anything else! i also have another engine that got a basic re-ring type job done, cost me 1100 to do (with some machining) and its running like a champ and taking some damn hard abuse.

i think a few things need to be figured out first, what all can you do to cars. you said your family are all mechanics, so i have to imagine they can help you with whatever, and if they can't i'm sure they know someone who can, so why not do a build and a turbo, might take you a little over 3k but i'm sure if you take the time and have patience you could defintately do it and do it good. if you don't want to wait then just go get a used engine (with a warrenty) like said above, put it in yourself, get all of the turbo parts, build your own charge pipes, exhaust, etc. you can piece together a nice turbo kit, plus get the engine and be under the 3k, and also get yourself hpt and you'll be good to go. that'll put you over the 200whp you want.
Goal is to make my N/A Auto faster then a manual without doing engine internals
not trying to thread jack you bud but does anyone know if you can run a 086
head on a stock computer?

You can run the head on the stock computer, but you cant run the HO cams on the stock computer very well. It would be pointless as our rev limiter is way lower than the 2.3 HO and would be out of the cams' powerband. What I want to do with my newest cav, is 086 head swap, with secret cams.
i thought you could only use the exhaust cam anyway. and there are a bunch of secret cams. which ones are you refering to.i plan on running an 086 head
as soon as i can figure out the specifics!

Secret cams ? why not go with HO Cams ? they go with the 086 Head. ..and about the Compression issue you can run 11:1 with no problems with HpTuners .
Well if your going N/A i think W41 cams are more aggresive and for N/A and Nitrous it the HO cams are great.
A Friend of mine has a Neon 2.4L DOHC built botom end all motor runs 12.8 at the 1/4 11.7 with a 100 shot.. good suspensio etc etc....
yeah but i can't afford hp so what can i do on a stock computer?
i.e. cams and head.
Dark for fear of failure
An inner gloom as wide as an eye and fermenting
Roiling hate
Death gripped my veins
Unveiling rancid petals
Flowering forth foul nectar
The space between a blink and a tear
Death blooms.-mudvayne
You cant run stock HO cams stock computer without machining and some sort of tuning device like HP tuners. Machining alone you MIGHT beable to..but deffinatly be pointless. Why have a powerband that is out of your RPM limiter?

makes sense. and i guess the head is pointless with the cams huh?

i think your going to need hp tuner on 11.1:
