I just picked up an oil filter relocator kit and an oil cooler, the lines that came with the kit are 1/2" as is the cooler core, my concern is that I'm going to loose too much oil pressure going such a distance through 1/2" lines, does anyone know if it should be OK, or do I need to install a higher volume oil pump, if so can I just take off the oil pan and change the pump with the motor in the car, or is it not accesable from below?? thanks for any info you can provide....
