Whats involved in fitting s13 injectors

[turbozx]

ok cheers, now iv got all the bit together now and am going to install the apexi this weekend the injectors some time after that, when i do install the s13 injectors obviously i will need to play with the apexi safc

i plan on getting it set up by proffessionals to get the optimum performance from it but as an initial set up to make the car drivable if i reduce the fueling by 27% at each rpm point then will that be ok

27% come from the fact that s13 injectors are 27% bigger than standard

iv also fitted an s13 tb so i can use the TPS so it can be mapped for part throttle.

an advice from anyone who has used this would be appriciated
