3sgte turbo upgrade which to get Options

[mk7celica]

Hello, I am kinda new here. I have a 1994 celica with a 3sgte swap with no engine mods but have a 3 inch dp and full 3 inch exhaust and a fcd, 4 inck air filter with custom air intake pipe and ebay special fmic. What I want to do is upgrade my turbo from the ct26. Dont want a ct27 or rebuild upgrade < figure I will want to upgrade again with these>Can I use any turbo I pick to my liking and bolt to my manifold with a adaptor or get a new manifold as long as I have A external wastegate and the down pipe that bolts to the turbo and exhaust. what I mean is if I have a turbo, wastegate and proper fittment to my manifold it will work? And also Do I have to have a ems to run right with the new turbo,I read that the ecu cuts out at 275 hp is that to the wheels or crank and is it the same for a jdm engine. Also ?i have some bigger injectors on my list to get is this a must with a new turbo?

ok I am putting it all together do you think with a ats rom tuned ecu I can go over 275hp? I checked out the turbo kit on here for sale the one you spoke of and I am on a smaller budget right now. I have a friend that will sell me his old gt35r turbo it has 12000 miles on it for 450 its a good deal. Tell me what you think of this setup the gt35r turbo,manifold or adaptor,ats rom tunes ecu, tial 44mm external wastegate, and downpipe to go with the turbo, st205 injectors. does this sound like it will work? and do you think I can hit 325hp? I can get allthe parts for 900 dollars 1000 is mt budget right now. And thanks for all the help, I am and have been pretty muchalone on getting my car to where I would like it.
