The stock injectors flow 440cc/min. There probably is not a big need to upgrade your injectors until you are making 280+ rwhp.
The standard injector upgrade is the 550cc from the turbo Supra. You can find a set of 4 for about $130 shipped. You shouldn't just drop them in because you will be spraying way too much fuel and running overly rich.
I think one of the best turbo upgrades is an oldie, but a goodie: Greddy TD06SH - 20g turbo. The turbo won't spool faster than stock, but the turbo is very efficient and will hold full boost until redline. Then again... I'm biased. :)
