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

also do i need to use the dropping resistor with the s13 injectors?

You are correct the adjustment is -27%

Even if you didnt use the s13 TB, the TPS's are interchangeable. I guess you'll have to wire it directly to the SAFC.

Nope, you dont need the dropping resistor

ye iv got 5volts across the tps and wired the output to the safc, thank for the info, id be lost without it!!

Which plug did you use. There's 2 plugs on the s13 TPS, one is a variable type and the other is an on/off type?

i used the variable one its on a flexable wire coming out of the sensor all wired in now need to sort the injectors out and an s13 clutch as mine has started to slip its only done 20k.

then off to someone like DP motorsports or rc devlopments for a mapping session
