Can a gtr fuel pump be used to upgrade my existing original one? rather than the usual bosch/walbro ones.. was looking at a remap and seting up to .9 bar safely, so gtr fuel pump, 1600 2ndrys and a fpr, does anyone run this setup plz? and probs i might face?
I think the normal upgrade would be the Supra pump. Straight drop in from memory.
