whats it out of and can i put it in a 97 cavalier what would i have to change ???

well, since your new im gonna explain it for you but next try to search so nobody can flame you ok
it came out of a 89-94 oldsmobile calais and achieca SCX. pontiac grand am and chevy beretta....all were 5speed and all have an "A" for the 8th letter in their VIN
as far as it fitting your car well..another thing you need to do is finish your profile cus i dont know what engine or tranny you have...if you have a 2.4 5speed its an easy swap..all you need is the engine and the pcm from a 1995 manual z24 or sunfire gt and itll bolt up to your tranny...if you have an automatic its alittle involved andnot really worth it since the HO makes most of its power on the high end
hope that helps,anything else just ask..and if i got anything wrong im sure the guys will correct me...
...just remember , inturn for my kindness please fill out your profile and do alittle searching theres lots of info on the motor and the swap on the .org......like this 2.3 swap
or here
another swap thread

yay ..you filled out the profile and everything! ..im so proud
