Lexus Is200 SE Project - ZAIS200 - 11-04-2021
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...

The 1zzfe green injectors are 250cc and with new is200 rubber o-rings they are a straight fit. No modifications needed. They wiring is direct fit

Ok and will these be fine for a mild turbo conversion or would it be better to go slightly higher?
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?

phaebo Thanks for the replies.
@ste176
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.

Ok thanks for the reply Stix, is there any truth to the 1JZ/2JZ injectors being compatible?

I've honestly no idea, mine are 650cc from a Subaru!

hmmmm and are those a straight swap?
or did you need to modify the loom or the head?

I had to change the plugs, but mine were brand new and came with new plugs so it wasn't a problem.
