Stroker kit?
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!

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

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

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.

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.

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.

I'm old school
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.

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?

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.

Whenever I think high boost Im thinking like 25+ pounds lol

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.

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.
