I just got me a j-spec S5 T2 motor with 99,xxx km to put in my FB and for the past couple days i have been looking up what to do , so here it is:

Large streeport
Doweled and Pin the motor
S5 BNR Stage 4 turbo
3" exhaust
Front mount intercooler (dont know size)
Injector rails from KGparts
microtech LT-10
Aeromotive A1000
Aeromotive regulator of some kind

but for injectors i am stumped... i want them to be good for 400+rwhp i only want 300+rwhp but i want it to be able to handle it if i go that high.

so what should size of injector should i go with on the primary and secondarys?

 

my guess on the injectors would be 1400cc primary and like 850cc secondary but im sure someone will get technical and correct me but that should get you in the general ball park

 

I'm not sure on the size, but usually the secondaries are the bigger two of the four.
