managed to get a FRST EFI motor down here , probably the rarest motor in South Africa

originally set up my Gotech Motor myself with std EFI injectors from an EFI XR3i with the T34 not connected(complete with XR3 EFi head)
ive had a delay getting my RC 500cc injectors and so thought i would use the FRST EFi injectors in the interim while i run the motor in for 1000km before taking it to Gotech for a full setup

problem is ,the std EFi injectors are exactly the same!!!!
picked it up when i swopped them out and did not get overfuelling as i suspected , my a/f meter stayed in the same place and the EGT was not running cooler
is this possible?
are the injectors the same?
EFi ones are blue , FRST are slightly darker(could be due to age?) . but the numbers on the plastic are the same except for perhaps serial or batch numers on the side

anyone got pics of std EFi and and FRST EFi ones

anybody have an idea of sizing
ive read the standard EFi ones are around 170cc?

i'm pretty sure there exactly the same mate the colour difference is probably age or summit like u said
