Yea you are def going to need a 255 fuel pump so you can pump enough gas to handle all this power. Especially with that 50trim. And i would also possibly upgrade your injectors the 550s may not be enough. With the bigger injectors youd be able to raise the boost even a good amount more than that. Do you have any internals done? Some HKS 272s wouldnt be a bad idea either. Is this your DD?
 
Not too sure if there are any other mods than that done. Yes it will be my daily driver for about a month - month and a half and then itll be garaged. Right now its at around stock boost. The MBC is off but i was gonna hook it up. Any recomendations on what kinda boost i should run right now? maybe like 10-11 PSI with what i have now?

any recomendations on the fuel pump? the walbro 255LP is what most people seem to use. Just wondering if i should go with the HP or not?
 
the walbro is fine (it just makes some noise) i went with the supra pump, althought it required some modification I was extremly happy with it, very little noise and great performance, i could run at 19 psi fine and i only have 550 injectors, but you should still consider upgrading, i KNow that i am.
 
anyone have any thoughts on what kinda boost i should run?

Why close the thread so soon? To answer your question about boost levels, you should probably be good around 10psi, but i wouldn't go much over that until you get that new fuel pump in and maybe some injectors as well. It's better to take it easy for a while until your car is ready to take a little more boost.
