Bought a T51R-KAI BB kit and gonna install it at my stock 2000 motor. I use PFC with digibox+commander, is wideband needed? What size primary/secondary injectors shall i use? i thought of 850cprimary 1300-1600 secondary what you think?

Also 2 HKS twin power or one is enough?

I will go with internal+external HKS fuel pumps and Apexi FRP as well as thinking of Apexi GT spec FMIC.

Any ideas?

 

I don't think you can run two HKS Twin Powers....can you?

I would run the 850/1600 you can never have enough fuel....but it really comes down to how much power you are looking to make. A wideband is very nice to have...is it necessary, not to own, but it is to tune with, or you can have a shop tune your car and use their wideband...that is up to you.

 

Screw the twin power, go with msd and blaster coils.
