dont worry about microcat.
yeah the part numbers are different but they fit and work and work fine, a few people i know run xr2i pumps, and belive me your be fine, as the 2i and FRST use the same injection system inc the injectors, its just the regulator thats adjusted different so the 2i 1.6/1.8 ans rs1800 pumps will work fine.
if ya running beiges you need a uprated pump mate.
once i checked the pump i will let ya know., but i can only dry test it mate by buzzing it over on a battery
yeah i got paypal mate, as for price, once ive tested it ill let ya know and you can make a offer dude.
