i have stock injectors in my 2001 neon now, have ported and polished my head, mopar performance cam and headers with srt catback exhaust. now my car boggs down bad when using full throttle, thinking may need one size up injector but cant find stock specs for stock injectors, any help will be appreciated.

 

welcome to DF. lurking for 2 years huh.

 

start by reading this introduction to fuel injector types and their pros and cons:

then there is much good additional info here:

big list of fuel injectors to be found on vehicles in junkyards

after reading all this you might then be confident that the first step for you would be to increase your fuel pressure a little,
rather than installing new injectors right off,
unless you want a better spray atomization with some of the new designs,
like those 13 hole types used on the Subaru WRX

good luck
