I currently I'm useing these old discontinued deatschwerks injectors and a old hydra ecu and I'm having a rough time idling and starting. I plan on switching to a megasquirt ecu that I have laying around here soon.

My question is should I stick with these old school discontinued injectors or would it be worth it to buy some Flow force injectors im on a tight budget so i wouldnt want to spend to much money where it's not worth it.

99 mazda miata with old school flying miata turbo kit.

 

FlowForce injectors will work a ton better. I think they are EV6 injectors while the Flowforce should be EV14.

 

Can have those cleaned/tested/flowed. I would want that done as you don’t know the history/age of them. Would save a little..
