Hi
I'm new on here. I just recently swapped a d15z1 motor into my sedan with the original dx transmission. I'm hoping ill get atleast upper 30s than later on swap to an hf. currently Im using a dx transmissions. I've converted my car into obd1. Ive Lowered it with ground control & tokico blues. I've installed headers but honestly I think headers are not the best with d15z1 motor, because of the 02 sensor. I've been experiencing a lot of hesitation and my 02 sensor light came on when the sensor is only two weeks old??.
