Ok so I've done tons of searches and a lot of reading about swapping k20a2 oil pumps into k24a2 motors, but what I would like to know is simply is it really necessary for me to do the oil pump upgrade with my 2006 k24a2 if I plan to only rev it to 7600-7800rpm and if it mostly a street car? I'm not saying it will never hit the track, but it wont be a regular thing. Additionally, if I do upgrade to the k20a2 pump, then I have read I will have to change to the k20a2 oil pan as well. So, I would like to know if I will get more or less or no change at all to the ground clearance between the bottom of the pan and the ground? I'm really worried that the aluminum pan will be damaged easily when the car bottoms out... I'm mainly asking because the motor is already in the car running so it'd be a real pain to pull it all out to do this...
