Can I use 550cc injectors on slightly more then stock build?

Ok, I've been searching and searching and figure I'd see if I got this right.

My Beast is a 1990 Talon AWD. The upgrades done to my Beast. Has a 3"turbo back exhaust with 2g exhaust manifold, Galant 16g turbo, open/hacked air ilter, BCS restrictor removed (11psi), have a aftermarket boost gauge, vacuum lines removed, EGR blocked, and maintence done.

My problem is. I just had a stock 450 injector fuse up on me, the resistance is way out I have 3 that show 2.6-2.8 ohms while the 4th is a few thousand. Soo instead of just doing it wrong and replacing the one with another I'm wanting to replace all 4 with another set with equal wear.

Locally I've been able to find a set of 550cc RC injectors that are 2 years old and with only a few thousand miles on them pretty good price I assume of 100buck. They were pulled for larger injectors. I need to get car up and running fast so the local will be faster. So far haven't had any luck finding a local 450. Well found one guy he wants 200 bucks for a used set...... Rediculous price for them and not paying that.

My question is. From what I've read from my searching is that to get the 550's to work I'd also need to either get a 2g Maf/converter, or a SAFC, and for sure a A/F gauge?

My future aims for the car is just about 300HP so don't think I'd want anything bigger then 550s for my build. I currently have a non-eprom ECU.

you will need something to tune or you will be too rich. like 10.0

Deffently pick up a 2g maf and wire it in, it fits the 550's pretty well. Get a wideband and an apexi!. Then tune away

Get a 2g maf installed for a better look and improved flow. You will still need to tune regardless on anything over 450cc injectors. The 2g maf will make it so there are less adjustments needed to use the 550s.

Sounds like 550s will be fine on your setup, but you are looking at picking up an AFC. Remember down the road, if you decide to go larger injectors, the largest an AFC is going to properly handle is about 680s.

This will help you with your quest for 300 hp. http://www.dsmtuners.com/forums/newbie-forum/360415-how-can-i-get-300hp-budget.html

Ended up having an awesome DSM'er from 30miles north drive down and deliver a set of blue top 450's for me for 80 bucks. Had 90k on them he went with 1000cc ones in a build on his Eclipse. They worked wonders.
