First of all what can of fuel management system are you going with.
If your going with a stand alone management system like a Haltech,Motec etc then go for low Ohm injectors.If your using a piggyback computer in conjuction with your stock ECU,purchase 550cc HIGH OHM injectors.

Just call rceng.com and tell them to you want 550cc injectors for a hyundai tiburon, and they will hook you up, they know exactly what to give ya.

They were very helpful when I bought my 440cc. But I would suggest until you have so way of modifying the injecto timings like a tec 2 or a haltech or motec or something.
I ahve my 440cc in with an safc and I ahev all sorts of problems.

how much boost ya plan on running?

I was thinking in going with the Motec but seems to complicated programing it, but the Link engine management system that comes with the UFB kit seems good enough, also i saw another not to good like a Motec but does the job, it is the MSD Multi-channel BTM w/fuel adder PN 6563 it cost around $410 and it can drive four additional fuel injectors i think i will be better going with this one, what do you say?
I was planning in running 10psi, and later on 14psi doing some more internal upgrades

The absolute biggest thing is to make sure you have a way to control those injectors before you plug them in. If you just strap a set of 440's or 550's to your car right now, it will NOT like it. Your gas mileage will turn to crap, it will not like to idle, you'll blow check engine lights for O2 sensor malfunction/failure and you'll probably clog your catalyst in about six weeks.

Only after you have some method of controlling them should you actually install them.
