    VXR fpr And GSI fpr?

    Are they different?

    As i have a set of injectors for a vxr but no FPR, i want my car mapping up and not sure if i need the fpr?

    Sorry if this is a dumb question, i cant find the answers lol

    I'm 99% that when you put VXR injectors on a GSi/ACT you need to use the Z20LET FPR so you would need to use your GSi FPR with the VXR injectors anyway...

    do the vxr injectors need a new rail etc or are they a direct replacement for the let ones??

    been thining of doing a few mods to my let then gettin it re-mapped, will it cause me problems/lower performance if i change them without getting it mapped?
