Civic EG

ok so ive just installed a b20z2 into my 93 civic eg hatch. The hatch was originally set up for a b18b turbo.when i purchased the car it had a hole in the block.but i do know the car was running fine before it blew it was a local guy who i knew.i pulled the z2 out of a car that i had in perfect running shape.it was obd2 and would absolutely scream not a single problem or cel no smoke knock nothing. when i installed the motor i used the intake,injectors,wire harness,distributor, and alternator from the obd1 hatch. i get the motor in fire it up and it sounds like a cammed 454. and is running super super rich.i know the car was setup for a turbo with 450cc injectors and 4 bar map sensor but i am running a stock p75 which controls fuel anyway right ? the car is running so poor and so rich it will not hardly rev it will but it falls all over itself. please any help would be nice

Stock ecu with 450cc injectors will do that. The ecu is sending a signal to the injectors in the form of duty cycle, no matter what cc injectors. So let's say stock injectors idle at 10% duty, with the ecu sending that same duty to bigger injectors they're gonna dump more fuel. They would need to only be at say 5% duty. These are not actual percentage values, just so you get an idea of what I'm saying. Ecu needs to be chipped/base mapped to run bigger injectors.

You also needs the stock map sensor with a stock ecu. It's not even reading that 4 bar without being chipped/base mapped. Stock injectors and oem map, it should run right.

big help thanks i will change injectors out and re wire in my stock map sensor
