STi V5 injector size??

wats up peeps just a quick Qs

what size injectors shold a V5 sti have???
and should they be ok for this setup?....... 3inch turbo back exhaust,, Green panel airfilter,,255lph fuelpump,, maped with a Apexi power fc?

Am I right sayin I shouldnt need to change the standerd injectors unless I go for a bigger turbo??

Steo

Your current injectors should be fine for all those mods...
Depends what size turbo ya going for....

Injectors are 440 - should be fine for about 330hp, I guess? With higher fuel pressure maybe a bit more?
But getting 500-550 can be also kind of way.
3" exhaust is to much I think - 2,5" should easy be enough up to 400hp

440cc


running at 3bar fuel presure with a uprated fuel reg be ok to 350bhp

thats grand lads thanks for the info

@Dave.. so i should be fine on my setup up to about 330bhp without a uprated fuel regulator?? so would i see beter gains if i fited the fuel reg before i got the ecu maped??

thanks agen lads.
