Im building a stroker motor from an m20, the final product will be ~3.1L. Do cat converters have a significant impact on the overall performance? Im not worried emissions tests b/c my car will most likely not be tested.appvalley tutuapp tweakbox

Hello everyone, So my e30 m10 318i has no power steering. Hard to turn is expected, but mine is like another level of heavy to turn when not moving. I have had the opportunity to check another one and it was much lighter to turn. What could be the case mine is so heavy? Anything that can be adjusted...
