The B58TU (from the Supra) is the only stock HPFP that is considered an upgrade to the N20, it does fit and will bolt into the housing and connect to the harness with minor adjustments. However the inlet and outlet ports on the pump face different orientations to the stock N20 pump. meaning custom Hard HPFP lines need to be made.
Considering most of those A90 Supra HPFP's go for close to what the Spool FX150 is selling for, then you add the cost of the additional parts to get the B58TU HPFP to work. It would be cheaper to just buy the Spool FX150 and have the tune flashed with new HPFP calibration data.
Alternatively Port injection kits already exist for the N20 which are cheaper than a HPFP upgrade. |
Would your ecu still be able to control fueling or is this the beginning of running a standalone? Are there piggyback type controllers?
I'm very interested in this process. Best of luck Kel and awesome help thus far navardi
