Hey guys I'm new here and to the honda world so be gentle on me if I say something that doesn't make sense. I bought a 1990 Civic EX with a 1.6L SOHC non V-tec engine and a 5spd manual trans. The previous owner Installed a T3/T4 turbo, intercooler, external wastegate, and BOV, the motor and intake manifold and fuel system appear to be stock.

okay, hope i gave enough info on the car, now to my problem, when i lean into the gas and it builds about 6-7psi the car starts breaking up and throws an engine light. I was told this is due to the factory injectors not being able to deliver enough fuel. Is this true? Should I uprade the injectors? if so what size? and what about the fuel pump and regulator? i would like to be able to push close to 10lbs w/o having it cut out. any insight would be greatly appreciated.

walbro 255 fuel pump. your oem regulator should be fine and some 450cc injectors should be fine and make sure you get your ecu tuned or you will blow it up. your prolly going to have to do a obd0 to obd1 swap to get it tuned
