MBC and fuel pump question.

[98blackspyder]

Got my hands on a mbc that I was thinking about throwing on. I dont have any fuel upgrades but from what Ive read it seems like its safe to up the boost to about 15psi on stock fuel system. Im supposed to get a 190 walbro fuel pump sometime this month from a friend that doesnt use it. When I get this fuel pump do I need bigger injectors to go with it or do I need a safc to tune it or anything like that?

Do a Fuel pump rewire and change that fuel filter Then You will be ok.
Might want to toss in some octane booster, Or a gallon of race fuel. which ever you prefer.
Not required but will help with Any knock you might see during extended driving or really hot ambient temps.

I have ran 15psi when my car was stock with no problems. You won't need to change anything else when you install the 190fp.

stock turbo?? on my ported B16g a 3rd gear pull, i hit 107% IDC on stock boost control(12.5psi), stock injectors

Assuming this is the stock 2g turbo, there isn't enough airflow/boost capacity to outrun the stock fuel pump (rewired!) or injectors.

yes it is the stock t25 turbo im running. Was going to put the mbc on this weekend but noticed there is a loud rattle on the front end when I make a right hand turn and when I take off quickly. Ay problems problems with this car. going to look at whats causing that before putting anything else on it.
