Somebody else might have already asked this question but i did not get a chance to read it. I swapped a b18a into my 1991 honda civic si hatch and i put a t3/t4 turbo on it and plan to run around 5 to 8 pounds of boost but i do not know what i should do about fuel management. any help would be apreciated, thanx.

 

If you have access to a dyno or datalogging, then chip the ECU and run Turboedit.
If you have NO access, then you can use an FMU/Inline pump on low boost, it'll be fine 5-7 psi.

 

for that much boost you can use a fmu. id use the 12:1 for every psi of boost you will get 12 psi 5x12=60psi of fuel pressure. i just wouldnt run a fmu with anything over 10 i believe the max they can hold is 10 giving 120psi of fuel pressure, just make sure you have toher supporting fuel mods to go along with the fmu..... also check out cartech fmu i had one, and they are pretty much the best u can buy, around 180.00
