does anybody make a stroker kit for are cars?

 

Destroke to a 2.0L possible. No stroker crank known yet.

 

i dont get why they dont have these parts for the 2.2 yet but they have everything for the 2.0 these people would make a killing if they started looking into the 2.2 more

 

....i feel retarded, but does anyone wanna explain what stroke and bore is? i could take a guess right now, so soeone tell me if im right
stroke=distance piston travels up and down
bore=circumfrence of piston

yes? no?

 

Actually theres a LOT of parts for the 2.2 EcoTec. Anything that fits on the 2.2 cavaliers that were ECOTEC's will fit us (internal wise)

You have a nice list of:
Forged Pistons from high to low compression and even overbored
Forged Connecting Rods
Cams
Valves
Valve Springs
Valve Guides
There are even forged Crankshafts

All you need to do is SEARCH and LOOK, especially with our SUPPORTING VENDORS

 

Yes, you got it on the first try. Stroke an engine -- increase the travel of piston, destroke -- reduce the travel of piston. 2.2 has longer stroke than a 2.0 -- same piston size. Shorter stroke = higher RPM potential, longer stroke = more torque.

Read up on 4-stroke engines cause there's more to learn. combustion chamber, deck height, mechanical and theoretical Vs actual compression, top dead center, bottom dead center, theoretical valve lift Vs Actual valve lift, tuned induction, and on and on. You've got a lot of learning to do.

okay, well then.....do you have any good sites that cover most of that? all i can think of is howstuffworks.com and i already read how a 4 stroke engine works..along with a few others

any suggestions?

 

Before trying to stroke this motor one should consider that this engine is not necesarrily the best platform for stroking. In fact quite opposite. The ecotec as proven by gm performance division runs strong in the high rpm's. Hence the 2.0 ecotec. They are the same motor but by destroking to allow high rpm's and the addition of a turbo charger the Ecotec motor can build tremendous power. Refer to the GMPP Ecotec Handbook and Buildbook for more information. They explain the amount of R&D that has already been completed in building the 1400hp Ecotec 2.0. Hahn Racecraft also has a lot of info on there website. Just something to consider before looking into stroking this motor.

 

You're going to have to get away from your computer.....go to one of those big buildings loaded with paper filled rectangular objects -- I think they're called books JK Magazines are another source -- Hot Rod, Popular Hot Rodding, etc. You can also go to a speed shop and ask to watch them when they build an engine. When you're building an engine/tranny, just remember it was put together by a person who was only provided with the basic how-to knowledge. If you have the same how-to knowledge you can do the same. Modding comes from either doing it yourself (taking a chance) or reading/listening about what others have tried.

 

You misunderstand. The "destroke" parts ARE for the 2.2 L61 engine. And there are just about and equal amount of parts for the two engines. You will never see a "stroker" kit for the car. Here's why...

The Ecotec was designed to be a forced induction, high reving motor. It has to do with the original Saab design. That sort of a design requires a short stroke crank. It can make a great deal of horsepower via high pressures and high RPM via low rotating mass. It won't make as much torque, but it's a compact sports car, not a truck.

Normally aspirated large displacement engines use stroker kits to produce slow revving, high torque engines. But stroking it is does not necessarily produce more horsepower.

The short throw crank for the L61 engine (2.2L) IS the performance upgrade. But for street use, you just don't need it. It's really for a pure race engine revving at close to 10,000 RPM. Your stock L61 crank can handle over 500 HP and 8000 RPM with no issues.

 

Besides for the stroke and bore question, was there any one specific thing you were still wondering about? We can answer those kind of questions. But if you want to know a large based general amount of knowledge, you will probably have to go school for that. I'm an Aircraft Powerplant mechanic and that part of took two years of my college education!

already did that a couple times in the past...but i did actually go back and read it again...
last time i read all the articles, i really didnt understand the valvetrain so well...however, 4 months on this forum later, i understood it all
