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?

 

same injector matey

 

yep the exact same injector mate!!!

 

WTF

surely 170CC injectors are close to 80% duty cycle at the standard 0.55BAR?

what then is the max boost with these injectors?

 

well really the injectors will prolly max out at around 160bhp...

i have beiges in mine, and mine is running 202bhp but the tuner says he dont want to try improve as the injectors will max out..

 

think they need to be changed at about 10/11 psi,then you would normally change to beiges...part number bosch 0280-150-701

 

depending on what management you runing

 

read GOTECH in my topic......

 

sorry doing to things at once,still i dout thast there anygood for big boost
