My rod bearing in my engine turned. I check the oil and found metal shaving in it. now i am wondering if the JDM STI ver. 7 2.0lt motor we fit onto a Ver. 3 wiring harness. I had it in mind that i could change the sensors on the ver. 7 to ver. 3. does anyone know that this can be done? I heard rumors that the ver. 7 has variable valve timing. is this true? i just don't want to get another Power FC.
