Larger injectors

[hoonigane]

Has anyone installed evo 8 450cc injectors on their 4g63 nts without changing ecu? Read the post where it said you can put larger incectors up to 400cc without changing ecu. What is power increase and any problems that came up?

im pretty sue evo8 injectors are 560cc
1g AT cars have 390cc injectors
1g MT and 2g cars have 450cc injectors

you can go with larger injectors and a SAFC

==================

4g63 nts

non turbo?
if your non turbo, i'm not sure. only time i have messed with injectors on a 1gnt was when doing a turbo conversion. we always swapped the ecu out for a turbo one. gotta add the resistor box for the injectors if you are gonna run turbo injectors on a 1gnt

You wont make any more power changing injectors. There's way more that goes into it. You get more power from bigger injectors when your putting more air into the engine like with forced induction. Then you're going to need a way to compensate for the injector size with some way of tuning the ecu.
