Default injectors!

okay guys, i heard that the injectors in an 89 to like 91 are bigger than the injectors in the 91 1/2? if this is true can you put the injectors from a 89 to make more power since they are bigger? or would they even fit into the 91 1/2? im lookin to do injectors cost effective

The '89 ~ '91 injector tips are 9mm in diameter. The '91.5 ~ '93 injector tips are 7mm in diameter. If one were to want to run the 7mm injectors in a 9mm engine, there are adapters available.
