Replacing injectors/coils on 3UZ

[Axis of Evil]

From an old thread,
Gloverman comment "If you have later 3uz injectors are bigger too so use injectors which match ecu. This was an early 3uz so same injectors "

I am going to replace injectors and coils on the 3UZ I am putting all new gaskets and seals into at the moment .
The engine is from a 2001 LS430 sold new in Australia. Pink injectors.
I may put a turbo on it sometime in the future, for moderate boost(5-7 lb?)
Is there an injector that delivers a bit more than standard, but will run on factory ECU now, unboosted and without modifying rails or harness?
What is difference in delivery between early 3UZ and late?
Are 2UZ injectors a drop in?

Anybody?

2uz injectors are not air assisted. Im still up in the air over whether the later different coloured injectors in the 3uz are bigger. I want to get my hands on some to test compared to the early ones.

Thanks,Kelvin.
Question; are the standard 3Uz injectors up to just moderate boost? (on factory ECU)

Ive seen and used for some boost. I prefer not as on calculations they arent good for much power.

What would you suggest as an upgrade that will work OK- balance between standard and when I get around to boosting it?

Not really. Some of the jz might work however I go straight to normal injector conversion and aftermarket ecu
