I have a 92 cavi with a 2.2 ohv,what is the biggest tb off another car that will work?
 
whatever you wanna make fit....
if you want you can make a 70+mm tb fit, and people have done it, but the obvious question should be, what exactly do you need.
bigger isnt always better.
 
 
this is what I know for my 2.4 I don't know much about 2.2's
Stock TB for a 2.4 is 52mm and you can safely go up to about 58-60?? mm's before you start losing performance.
Unless you're getting boosted you shouldn't go too big of TB.
I know most people are happy with the 2.3's TB because it's at 56mm 
correct me if I'm wrong though. and like I said I Don't know if this applies for 2.2's
 
let me refresh theQ......What is the biggesy tb that will give me morep proformance???   Innari thnxs for input
 
stick with a 56 then... if you care any about low end.  the 62 sold can be overkill for most.57-59 if you can find some floating around, but are rare as those companies have been gone for up to 5 years now.
but 56 froma  2.3 engine.  
 
 
you cna always bore your TB out to whatever size you want
