Saturn ION

[Hudson]

The engine in the ION is very similar to the 2.2L DOHC (different from the OHV 2.2L) engine found in other FWD cars from GM. It's in the Cavalier/Sunfire and Grand Am/Alero as well as the Saturn L-Series.

What's the price tag on the new ION?

Yes it is. By the way, that is "echotech" not "econotech" ya ball buster. It is also tuned way down for the EPA and air people. Add a simple resistor to the air intake sensor and you will be up 8-10 hp without even bolting parts on. Cost $5.00. This engine has been co-devolped by GM and Lotus. Smooth, sound and a great paltform for power mods.

when are the red line cars coming out??
that's what starting to interest me about Saturn...

[miamisl2]

dang nabbit. its an ecotec not econotech not echotech!

its a 2.2L 140hp 142ftlbs

it was first in the L series saturn. now its in the vue, the ions and from now on into next year just about every gm 4cyl car out there. saabs have them, cavaliers/sunfires i believe already do... i forgot the others.

best 4cyl engine ever! (im my opinion of course)

i dont feel like lookin for it but if you guys wanna research what gmp (general motors performance) has done with an ecotec, please look it up. 1,000+ horsepower...maybe 6.9 but i know for sure 7.0/7.1 second quarter mile times in a drag cavalier with the 2.2...engine can handle 400 hp stock....block can handle 700hp.

and please, no one buy that intake resistor on ebay for $5...it does nothing and costs like 10 cents to make, try radioshack if you really want it.

Ah cripe, am I throw-en in too many constanants again.

Your damn straite its of the best. Have you stopped to look at the factory stock intake chambers that help to boost naturally aspired intake velocity.

Not bad for a US bred motor. (well, Lotus fed most of the design to GM so there.) Is Lotus GM too?

I would be curious to see what the change in Torque/HP are with a standard wide-open intake. Seeing as how this engine has been tuned down for MPG and EPA, I would bet the supprise is a good one.

Hey bro, On the Resistor caper. What hardware mods did you combine it with?

I stumbled on the same Idea about 2 years ago and found that it does work with some minor limitations. If you correctly guage the resistance
to turn out the right amount of fuel, I found a considerable increase in both below 4k and above 4k rpm. With some essential bolt-ons of course. By itself or if too much resistance is applied, a loss of power may be experienced.(too much fuel) Not only does it adjust the pulse width but a minor advance in timing can be gained as well.

The big issue with Saturn PCM's is that they will always try to achieve
stoichiometric fuel ratios. (Lean and clean) At engine shut down, if the resistor is left in line with the intake temp sensor it becomes part of the closing reading.

The way I found to get arround that is to install a true bypass switch and turn the added resistance circuit off a few minutes before shut down. When you start the engine next time, do not turn the added resistance back on until the engine has finished with warm-up. This way it is always an incidental reading, not part of the cluster of constant averages.
Ehhhhhhh?

As well because ambient conditions change constantly, I devised a block of resistance in 1/2 ohm increments so I could from the cock pit make the adjustment on the fly. Position 1 is bypass, from there we climb to 10 ohms 1/2 ohm at a time.

Or maybe I am just a bull shisster. try it, you tell me.

Keep yer footers mashed down till the gass is gone.

man i hate it when i write a reply and it doesnt go through!!!!!!!!!

haha

are you australian or canadian?

yes lotus has been a part of the design or gm borrowed from them or something...and something else really strange... the lotus elan has the same steering wheel as first gen sl/sw saturns, so obviously there is something between them and gm... they are also close with isuzu it seems

as for the intake ports, i have not seen them but i would be very interested in knowing what they look like and how they increase air velocity to the chambers. venturi effect or what kind of shape do they use? i would also definetly like to see a dyno on an ecotec with the intake/exhaust opened up.

as for the iat resistor thing...i have never tried it, and i had heard of people having problems with it under different conditions, the details i'm not sure of but i'm sure its what you're describing...im sure it was related with timing

i'm not very knowledable in the electrical field, your expertise has humbled me... so id wish you could explain how the iat works, what ohms it outputs or whatever and how different temperatures affect its output...i like what you're talking about there by changing the ohms from inside your car, but how do you know which ohms to leave it at, trial and error type deal? what do you mean by the resistor becomes part of the closed reading at shut down.

i would be very interested in the specifics

by the way i have found my car to run better with lowered fuel pressure, ive only done a few bolt ons and the such, nothing requiring much extra fuel like forced induction/nitrous/headwork/raising compression or something of that nature. funny though.

what have you done to your car? and what do you drive.

The Redline comes out in 2004
