Good question, I'd like to know too, need to be looking for the right uprated injectors too, trying to decide which ones would be best as i want to try get injectors that need little or no modifications, I've heard the 1JZ or 2JZ injectors fit the fine but i'm unsure if they fit the loom right read this off one of the australian forums somewhere...

What i mean is i'm looking to get between 250 and 300 hp (at the flywheel of course) using a GT28 or a TDO4 turbo, will the 1ZZ injectors be sufficient or should i go for an injector rated above 300CC? and a higher rated fuel pump?
Ok and will these be fine for a mild turbo conversion or would it be better to go slightly higher?

phaebo Thanks for the replies.

The stuttering is probably caused by the small injectors. My car used to stutter a little bit under 2000rpm with foot down. But now i have bigger injectors green 1zzfe injectors the car doesnt stutter anymore.
Still running the blackbox from patrick.
I can imagine that the stutter will be more with a bigger pulley because more air in the inlet causes a leaner air fuel ratio
The car stutters regardless of pulley size, we think it's too much load on the throttle body motor.

1zz should be fine, but bigger is always better.
You should definitely fit a bigger pump, fpr and fuel return line.
