I have a 98 cavalier 2.2 5 speed, it is a purpose built dirt track car, now with the 2.2 we are down on power, since most car are dohc or a little more built to have better handleing, we got the car to handle great now, but now back to the power thing, i search couldnt find any dyno sheets on the 2.3l tb swap to the 2.2 what gain and loses would i see. if there is some other options for small non noticable engine mods, since were not spose to change anything with the motor. any help would be apprieciated

Boring out the stock TB would be your best bet the 2.3 tb would most likely be noticed since it doesnt bolt up the same.

Overkill Engineering Motorsports does TB boring and sleeving so it can look stock from the outside but flow much better for the higher RPMs you turn on a dirt track.

I think bigfoot is blurry,
that's the problem. It's not the photographer's fault. Bigfoot is blurry. And that's extra
scary to me. There's a large, out-of-focus monster, roaming the countryside.
"Run! He's fuzzy!" "Get outta here!"
