I'm buying a 2002 cavalier and its a 2.2 i dont think its the ecotech but my question is can i twin turbo that motor after a complete rebuild?
Also need some info on where i can get prices on air bag suspenstion
Thanks.
 
 First of all this should be in the boost forum. That will have all the answers you could possibly need.
 Secondly a 4 cylinder engine doesn't need two turbo. It would lose all boost efficiancy.
 
 
Also, I'm 90% sure its not the eco.
 
 
you can get an eco in a 2002.  
as for tt, i think its pretty pointless to me.  the amount of money you dump into the car to make it a tt, you would be better off just building the motor to run 1 turbo with alot of boost
