Hey guys, I'm just wondering does anyone make a stroker kit for the 2.2L Ecotec? You can never have too much torque of it's set up properly,lol. I'm picking up my 06' LT 2dr in 2 weeks I can't wait to uncork the Ecotecs power potentional,thanks!

not that i know of, and ive been around Ecotec's for the last 3 years. I havn't herd or seen n e thing.

cool. I got a new Sedan. I love it!

Can't wait to pull my SS out of storage when it warms up...

http://www.importperformanceparts.net/ they have to bore the 2.2 ecotec to 86.5mm but its for the cavalier but the engines shouldn't be different

celicacobalt

2.2 to 2.4 ? that would be cool

yea.... if you want a stroker get the crank, pistons and rods for the 2.4..that should make a noticable improvement

celicacobalt

would that really work

GTPsRule

Useless. The extra .2 liters wont be worth the money. Now if you could bore and stroke it, you might have something. But just a tiny stroke increase like that is a lot of money for very little gain. Unless someone can prove me wrong Although I guess it would be a good opportunity to install a forged bottom end that can handle massive amounts of boost or nitrous, or both

celicacobalt

agreed

i dont knwo if it will work. but the .2 liters.....most stroker kits only change .2 or so liters...for 4 cylinders anyways

GTPsRule

That is indeed correct. In the case of a 350 small block being converted to a 383 stroker, if you were to split the motor in half, it would come out to a .2705 increase per bank of cylinders, just a bit more than what the cobalt would come to. But theres 2 banks of cylinders, so the effect of stroking is going to be more apparent because its being multiplied by 8 cylinders instead of only 4. As I said, I think the money could be better spent, unless you want to build up the bottom end to handle boost or nitrous. In that case, you might as well stroke it since youre doing the work anyways. But relying on a stroke increase that only nets .2 liters to give your N/A motor an increase in power isnt too wise and will leave you disappointed

i was going to beef the bottom end up and run a ridiculous hybrid turbo system that my friend wants to develop. he developed his own turbo kit for his 04 Jetta GLI, hes currently running 285hp and 330lbft tq on a small ass German Audi TT K04 turbo with very few other custom mods besides ECU, intercooler and headers, his exhaust is still stock and he has absolutely bone stock internals. the potential of a 2.2L Ecotec under the same circumstances are ridiculous and is way cheaper than any kit.

IonNinja

before anyone else says something...

headers?!? on a 4 cylinder...and a turbocharged car at that.

n4ggs

a major reason for gettin a stroker kit is when you are upgrading the bottom end to handle more power why not stroke it. doesnt makes sense to stroke a 2.2 to 2.4 if thats all you are doing.

GTPsRule

LOL good catch. I cant believe people still still headers when referring to a 4 bangers
About it being on a turbo car, it can pretty much go either way (header or manifold) if its an aftermarket tubular piece. But I have a feeling this particular car just has some kind of OEM manifold with a flange welded onto it.
Umm yeah, basically what I said up top in my 2 responses

Halfcent

Stroking this engine alone would be a horrible waste of money. You would be taking apart your engine and doing some serious machining to the block and a complete replacement of your internals to accomplish very little gain. And I'm not even sure it's possible. This is a short stroke 4 cylinder block. I don't think the cylinders would be long enough to handle any more stroke as it is.

I am completely a fan of internal replacement. I just finished doing it myself in fact. But the amount of power you can obtain with an upgraded rotating assembly and a power adder like nitrous or turbo would be FAR better dollar for dollar then having the engine stroked.

celicacobalt

yeah like everyone siad the stroking would be good as long as you are making the engine bulletproof at the same time and adding plenty of boost

Stealth06LT

sorry its the muscle car builder in me that said headers,lol i mean exhaust manifold guys, although when my friend ordered them from alphawerks for his RSX Type S they said headers and most aftermarket companies will still say headers, but w/e to each his own. I think i'm going to weld up my own "exhaust manifold" rather than buy an aftermarket one because equal length runners are so damn expensive on aftermarket ones. I think you can buy the flange from GM right?

Stealth06LT

yea a medium sized turbo that spools up fairly quickly that i could run at fairly high boost with thicker internals is what I want to do in the long run, i figured stroking it would be a good idea, anything to allow for ridiculous hp and tq later on with a turbo.

GTPsRule

Thats kind of an oxymoron, especially with a 4 cylinder. Youre either gonna get quick spool or high boost. Its real tough to get both of them, unless by high boost you mean 15 maybe 20 pounds, in which case you could get a 16G to get you quick spool and high boost. Whenever I think high boost Im thinking like 25+ pounds lol

Stealth06LT

yea well I should have specified running high enough boost as not to max out the capabilities of the setup, lol 15-20 would be fine, most aftermarket turbo kits for 4 bangers only run 6-10psi because people don't realize that when you get a turbo kit you should upgrade injectors and fuel pump as well before you turn up the boost. The turbo kit is great and all but you need to cover the spread first and do it safely. anyone can throw a turbo on their car, buy a boost controller and boost it to 25-30lb, if they don't compensate for fuel delivery and all other internal factors those same people can also watch their engines blow up,lol

forcedgminduction

hey while you are going with higher compression making longer strokes and high boost, you can also shave your heads to make the combustion chambers smaller and see how high you can launch engine parts. not saying it cant be done, but you better be ready to shell out some bucks on a true race prep engine. If you every get it legally pass most emmission laws most states have.

GTPsRule

Dude what are you talking about? Why would he need a "true race prep engine"???

forcedgminduction

yes the block could hold, but your valves, pistons, crank, conecting rods, and cam probably wouldnt hold. Even the gm guide book says they had to beef up the crank and rods to get 500 hp out of the block. if he is wanting to run at least 25 psi, that is the phase 5. plus common sense say that if your run that much boost, you would need a better bottom end in the motor. If you put a better bottom end, you should do the same to the top, to make the most power.
