hey, im new so not sure if im doin this right but here it goes lol. i have a 93 civic which was swapped to a d15b with turbo and i swapped it into my 2000 civic dx. i have done all the necessary changes such as a obd2b to obd1 jumper harness, im running a p28 ecu, ive changed the 3 wire iacv to a 2 wire, changed the injector plugs, dizzy wiring, altenator, etc. The white iat plug on the d15b head is now not connected. She also has an aftermarket map that i had to wire into my harness. Havn't wired vtec yet. The engine was running blue top 450 injectors and a resistor box from an eclipse. But of course seeming it was my first engine swap, i had no idea what the resistor box was. I new it was wired up in the 93 but didnt wire it into my car.

So i fired her up (without the resistor box) and she ran fine. I went for a little spin and when i went to step her down, she bogged and shut down on me. She washed herself down on her cylinders. So i brought her back and drained the oil, etc to try and clean her out. Then i ran her off stock 240 injectors for a little bit until i found out how to wire up the resistor box. She ran ok off the 240s but was starting to wash herself down again. I rewired the 450 injectors again and the resistor box once i dropped the oil again but she will not fire up with the 450s. she still runs off the 240s but not at all with the 450s and resistor box. I have no idea whats causing her not to run with the 450s. She ran perfect while in the 93. I was thinking maybe the injector drive in the ecu is fried and just pumping steady flow to the injectors?? Other than that im stumped for ideas.
