hahaha
ahh draven u funny cunt
the best injectors are the ones that match the ECU you ae using
ie, if its an ae82 ecu get the std injectors for that ecu
if its an ae92 get the green injectors for that ecu
if its got an aftermarket ecu get the biggest ones you can find

uhhhh, the ones that come standard on your 4age perhaps??? Unless you have an issue with not enough fuel being supplied there's no need to upgrade your injectors.
It also depends on which particular 4age you have if you want to check the flow rates.

I think that's the best idea. I'm upgrading to turbo so needed larger injectors but if you're keeping it stock, there's simply no need

no performance upgrade is given by upgrading injectors with a stock ECU anyhow
shit its probably not even possible with the impedance differences and such

all u do is maybe gain 5% up top if yr lucky and then fuck up the other 95% of rev range
say it so many times but not many listen
toyota spend many many hours perfecting the tune for good fuel economy and good power
so if u keep a std ecu keep the std injectors
full out power is shit if u get shit fuel economy or performance below 5000 on an everyday street car

hence my initial post.
stock engine = stock injectors.
hell, I've cranked another 30% power out of my baby and still running stock injectors.

Big enough to flow your power requirements. Considering you're not suggesting any major mods, standard is best.

What you're suggesting is that more airflow (achieved by improved exhaust efficiency and better cylinder scavenging) will require more fuel delivery in absolute terms to maintain optimal AFRs.
This is technically correct, however standard injectors will be specced with a significant reserve, ie. at max fuel demand of the standard motor you'll only achieve 75%** duty cycle. So by increasing fuel demand slightly by increasing exhaust efficiency, you'll perhaps push the injectors to 78%** duty cycle now? They are still not in need of replacement with larger injectors.
Hope this is informative.
** this is a randomly selected figure used as an illustrative example only
shit, it's 4am... no wonder
