advice
 

1994wrx import
what would be the advantages of fitting 740cc injectors over 550cc ones
looking for 550cc blue tops as advised by fellow member but could not find any but have found 740,s
upgardes to fit
walbo pump and reg
apexi ecu
thanks

judging by the added spec it isnt even worth adding 550cc

so would 740 injectors be of any benefit?
as i was told i,m nearing the limit of the original ones

how do you know you have maxed out your injectors??? need a big spec to run 740cc

just advice i was given
with full decat pump etc didn,t want blow up anything as previous threads mods cost dosh and when they go bang cost even more
would like/wish to get near the 300bhp mark someday safely

get your uprated fuel pump and reg on then get that apexi ecu mapped and it will be safe enough :) plus you can turn the fuel pressure up to get more out of your 380cc injectors, then you could decide if you need to go bigger :)

thanks
