is ther a throttle body swap for the 2200 engine of a 2000 cavi with a biger bore
search for the 2.3 HO swap, youll find an unGODLY amount of information on it
it is also possible to bore the stock TB to 56mm, you just need to get a butterfly plate to match. i just picked a 56mm 2200 TB up in the classifieds.
