7AGZE help!!!!

[nzbullet]

ok so here we go,

i have a 1989 ae92 gt corolla sedan (in nz)

it currently has to my knowledge as i swapped this car for a rusty old civic

ok so 7afe block from a caldina
big port 4age head original from car
ae92? levin 4agze supercharger

this old girl is now known as the pig, she was running like crap so with limited tools and even more limited time i sent it in to find out why,

what they came back with sounds expensive,

the timing was at 40 degrees and about 3 teeth out on the cambelt

that all been set back to normal she starts fine and runs good for about a minute,

whats happening is it is running way too much fuel and fowling the plugs, its loosing compression once warm and the huge amount of fuel is washing away the oil from the rings,

the mechanic said i need an aftermarket ecu, what i dont know is what ecu is in it, i also dont know what the injectors or anything else is from,

so yes very much in need of some experienced guidance here,

so yea 7agze 5psi boost
unsure on ecu
over fueling
fowling plugs
losing compression when warm
no afm been from nz i believe its all jdm down here

any help or advice is welcome,
if you need more info let me know and ill try find out,

so could this be that i only have a 4age ecu and not a 4agze ecu which is causing the over fueling?
