Thanks for the info, Integra type-R. I'm thinking to get VAFC-II (cause it's almost impossible to get hondata here) and AEM UEGO wideband air/fuel ratio, do you think if I set up the air/fuel ratio correctly I will feel a big (or at least noticeable) different in my car performance? Also, with my engine set up with B16A injector (I think the injector size is the same as B20b) is it okay to set the fuel pressure same as stock? Not to lean? Thanks.
