New Injectors??? ECU upgrade or piggyback?

[sports4life_3]

I have a 94 altima with the ka24de, im putting a t25 turbo on here in the next month. Will the fuel keep up with the stock injectors, or should i really look into putting bigger injectors in???

I also was wanting to know whether i should upgrade to a performance ECU or just invest in a piggyback air/fuel system to use with the new turbo. Any comments are helpful, thanks

Hey, When you instal the T25 you should be ok on low boost with stock ECU and injectors. I wouldn't go past 7 to possibly 10psi. I know that a stock T25 runs out of efficiency at 13psi roughly. (15 tops). To be safe you can go a size up on the injectors but it might not be nessesary. My friend that has this engine had a T28 that I put in for him and he has never exceeded 8psi and is running stock everything except for fuel preasure regulator. (increase fuel psi a bit). I would recomend this for you. His engine had 185.000km on it so it wasn't to old. If your Miles or Kilometers are fairly low you might be able to eventualy hit 10 psi. On stock rings you might end up with pre-mature wear and reduce the life of the motor. Realisticly, a turbo charged motor has a bit better then naturally aspirated rings. Your rings might not last as long due to forced induction with more cylinder preasures on NA rings. I hope I have given you a bit of useful info. Maybe some one else has a bit better info on the topicJust my 2 centsGood luck
