question about upgraded injectors

[spooled-up]

Hello all!! I am unsure if this is the correct area to post this but i am limited to where i can post. I have serched but cant find a definite answer to my particular question. I have a 92 gvr4, built bottom end 9:1 compression, 255 pump with rewire, fmic, was told it has small 16g but think its 14b ( previous owner lied about a few things so i question witch one it is), tru boost controller and wideband. My question is can i safely and efficiently run 550cc injectors and 272 cams on stock eprom ecu. Will be going to a megasquirt maf-less stand alone sometime in 2018 with 1000cc injectors and evo3 turbo but thats another discussion. Any input would be greatly appreciated.

Don't run anything but the stock 450 injectors without a way to tune.

Are you positive you have a built engine? Id look through and confirm what you have for parts on your car. Alot of people like to claim the engine is "built" If those mods are indeed accurate you might want to consider dsmlink.....

Im positive its built bottom cuz i built it after my timing belt jumped

No you cannot run larger injectors without some way to compensate.

I am able to get an ecu with link but its out of a 98 gst with 6 bolt motor. Im under the impression its too new to work on a 1g but figured id ask anyways. Thanks all.

I don't believe a 2g ecu will work on a 1g. You can easily tell the difference between a 14b and a 16g. Take off the intake pipe and look at the fins or look at the serial number on the compressor housing.
