Ok j-body fam i have a couple of questions i hope that can be answered.I was wondering what is da maxium power u can get out of a out of a high powered non turbo eco?
Let me re-phrase question, that wit a turbo kit giving a eco 235 hp @ 9 psi whats da highest hp i can get out of performance tuned eco wit no boost at all, like maybe i get ma eco 2 throw down about 200 hp at da wheels or more non BOOSTED.

And what will i have to do (if possible) to atleast reach 200whp or more? Because a

~2003 DODGE STRATUS 3.0-V6 (200HP)@ $14,850
~2004 DODGE SRT-4 2.4-TURBOCHARGED (230HP)@ $20,700
~2005 CHEVY COBALT 2.0 SUPERCHARGED (205HP)@$21,430
and
A 2003 PONTIAC SUNFIRE 4CYL 2.2 ECOTEC-(N/A)@ (250HP)
IS SIMPLY
(Priceless)

intake
header
exhaust
throttle body
new or ported intake manifold
cams
higher compression
pulley's
P&P head.

its gonna cost you you almost as much if not more for a turbo kit if you do it right.

he'll need more than that. Also look into vlaves and springs.
Other than parts, you need to get a good air/fuel mixture. And ecu tuning will be a must. Currently, as we all know, its not out yet.

You can get over 200hp at the wheels with higher compression pistons(11.2:1), new rods, p&p, header and exhaust, and a lighter pulley. You can get the rods for around $300, the pistons for around $600, header and exhaust(2.5 inch) I think people have said around $500, pulley around $150, but the p&p head might run around $1000.

If you throw in a bigger tb, jump to 12:1 pistons(using 93 octane gas), and get your crankshaft lightened and knife edged, and then find a set of cams that actually work, you could probably see 225hp at the wheels.

Then you have to figure out how to tune it!!!!!!!!!!!! The stock ECM isnt going to get it done without a million CELs.

I think big power NA is noble but in the end, its just more efficient and cheaper to boost it, IMO. Plus you have options after that.

i reluctantly agree, there's just something about all motor that i like...that's kinda a honda thing for me tho...as long as i have a cav, probably gonna be lookin into boost...

  

I mean i love boost as much as da next guy , like da sound of da bov going off,releasing a
furiou sound, but i feel as if anybody can just throw on a turbo kit and easly get power that way. its like taking steriods to get diesel,but when u can do it with out any drug or help u no ur a real beast.

but thanks fam for da info

I haven't heard of anyone that put a 12:1 compression in an eco. If you do, you would probably need more than 93 octane just because we cant tune the ecu. This is what i have been told.

I want to raise my compression, but if i were you, i would wait till the software comes out. Also, does anyone know if a 12:1 compression will fit? I don't think anyone has tried it.

well you could add a Bottle and hide it realy well. But any way also with that high of a compression i think might make life miserable with detonation. If you want to do a all motor build up i would wait until those 2.4 ecotecs come around. i mean a motor with 170 hp and more stroke will have a better chance of your goal 200 also would probaly be less of a pain

Actually the stock pcm will work with the first set of mods I listed, if you knew how to tune it you could get more power for the same mods though, which would be nice.

FI will always create more power than NA, but it's not always cheaper, just usually easier. If you can do the work yourself you can get more power out NA for cheaper, but can always build a FI engine higher in the long run.

well you would be starting with about 125-130 at the wheels to begin with

Intake
RSM 62mm TB
RSM Lightened Crank Pulley
MSD Ignition
Pacesetter Header
Magnaflow Cat
Borla Muffler
Some Mild Cams that still work with the PCM without throwing codes
Spec stage 1 clutch
Spec or Fidanza flywheel
RSM, or Patriot Cylinder Head
Adjustable Cam Gears
11:5 or 12:0 Forged Pistons bored .040 over, maybe even .060 over
Forged Rods
Rk Sport upper Mount
RSM Lower Mount
Prothane Tranny Mount
Lightened Crankshaft

If you went with the .060 over Pistons at 12:0 along with everything else on that list you might see 200whp i dunno nobody has ever went all out all motor yet amoung us

One of the magazines did go all motor on a cavalier, they used what I listed first in my post and were over 200 at the wheels, if you did 12:1 and .040 over plus everything else there you would probably be over 250 at the wheels, and it is possible to get to 300 at the wheels if you used the right parts.

drill a hole n ur CAT 4 +15HP dood.

12:1 that is crazy! try 103 octane

I was actually wanting to do the same thing, I wanna swap the ecotec into my car, but use the Mantapart Version four ecotec crate engine, the thing seems badass, comes fully loaded, check it out, what kind of numbers do you guys think this thing will put out?

Its on the home page at Mantapart.com!

you really think going .040 over at 12:0 would make that much power?

I would never order anything from Mantapart, its prob a stock engine with some dremel parts

So it is possible 2 reach 200whp and beyond wit da performance mods that were listed ,is it possible to use what ya said and be able to reach pass 300whp also wit a turbo kit?or supercharger?

well if your going to do boost you have to mod accordingly you cant one day just change your mind after your motor is set up for NA, you cant just run boost with an overbore piston and a high compression, your EGTs would be through the roof unless it ran on methanol or something

Hey GM came out with the ecotech build book..stock-250HP...250-400HP--400-600HP--and 600-1000HP!!!


Elmer the wricer hunter..."Shhh be vewy vewy quiet...I'm huntin wrice"
Kill da wriiiicer...Kill da Wricerrrrr..kill daaa wriccceeerr!!!

I no,u just cant change ur mind,im just asking questions.Im try n to research and ask question about ma j-body.
Thanks 4 da info fam

If you change to high compression you will not want to boost on top of that. If you keep the stock compression, overbore, then do every bolt on, plus p&p head, you can probably see 200whp, but I'm not 100% sure on that. After that you could boost but with the stock 10:1 you may have problems until you can tune it.

When I get home I will try to remember to look up the magazine and month/year that had the rksport cavalier, like I said they were at or over 200whp with what I first mentioned. So adding overbore plus a few other mods and going from 11:1 to 12:1(it makes a noticable difference there) can get you a fair amount higher if you know what your doing.


As for 12:1 needing 103 octane, look up the 2000+(pretty sure that's right) toyata celica gt-s, and look up jaguars, that will set it straight.

Thank fam 4 do n that and 4 answering more of ma questions, just try n to get da facts straight and i hope nobody come out wit that yellow stickers give u 15-20 hp stuff.

Actually, yes and no. Not everyone can save $4,000 and get a proper turbo kit well tuned and respond good. There are people out there who cheap it out and sometimes get good gains but because of improper installation and/or heating issues, it will go soon.

In all honesty, I was going to TRY that but I did lots of research and it will take much more money and less gains to make high power all motor. If we had VVT (Variable Valve Timing) then it would be much easier. That's why the Honda guys brag about V-Tec.

Having a 4 cylinder without VVT is a dissadvantage all motor, that's why the only real way to go is boost. Plus with all motor, you have a limit. Boost, your limits is MUCH more. If you do it properly, you can have a 300+ Boosted J-body. You won't reach those #s all motor.

Really, it all depends on how much power and how much money you want to spend. Good luck to whatever you decide to do.

I myself am praying to the car gods that the new vvt off the 2.4 eco will be backwards compatable with a little work. We shall have to wait and see though. My goal is for a roughly 300hp(at crank) NA motor, but I have taken on a few new projects recently which is really slowing me down now, plus I am debating if I even want a 300hp engine for a daily driver.
