A wet kit is cheaper and easier than swapping out injectors. Although Sonata injectors will work with a N/A motor, however under normal non-nos use, you could run richer than you really need. The wet kit only adds fuel when it is needed so you will run economically as well as have the power when you need it.

I don’t normally disagree with you, but dry nitrous/turbo guys have been using additional pressure to increase the amount of fuel that passes through the injectors in a given amount of time for a long time. Thats how a dry kit works and the RRFPR is probably the easiest way to get the extra fuel in a low boost setup. Its probably not the best way to do it, but it works. Hell even hyundai did it with the beta2. They dropped the injector size and bumped the fuel pressure to get better mid range response and better atomization (emissions) but have the same overall flow.




Also the 290cc's will trip a CEL if you dont have some sort of electronic controls atleast at idle. Not to mention the ecm will still have no idea when the nitrous is flowing. It will bump the flow a little when it sees the drop in temperature, but it won’t recognize the extra air because its programmed to read air as 21%ish O2, not the 33% O2.
