The stock K20 oil pump is a great piece for up to 9,000 rpm continuous duty. Past that, there can be cavitation issues. Our ported pump will allow continuous use above 9,000 rpm, and we have run the pump as high as 11,300 rpm with great success. We start with a brand new OEM oil pump from Honda, disassemble and port and notch for K24 fitment. The pump is then cleaned, oiled, and reassembled.
FITS K20 and K24 Engines!
