  1. Problems & Solutions RSX
    I’ve been in love with Acura RSX since my first 05 base model and I just recently bought an 06 type S and I love it to death, only problem is this car has the K20z1 original engine, and the transmission of an 04 with less mileage. Because of this, the previous owner had no speedometer, so now I...

  11. Transmission & Drive Train RSX
    Has anyone ever mounted a 6 speed 4.7 final drive on a base rsx k20a3? I've searched and threads too old to ask someone how it is. I did it but I mismatched the clutch and flywheel/ pressure plate assembly and couldn't disengage the clutch. I drove it around and it was bogging out or didn't seem...
  12. Problems & Solutions RSX
    I've searched multiple forums so I have become aware that it is more "tricky" to put a k20z1 motor into older an older model RSX. Normally people just say "get a k20a2 and avoid the hassle". However, I recently found a donor car that was in great condition minus a small front passenger side...

    Today my car decided to go up in smoke. I pulled into a parking lot and found that my oil filter completely exploded off of the engine block.
