Suggested Injector Size

On a basicly stock greddy setup running 5-5.5psi what would be a good upgraded injector size? I'm selling the car soon so don't want to go crazy but figured if I picked up a set of 1.8L injectors and throw them in it would be cheap and effective. Not sure how big the 1.6L's are and how big the 1.8L's are so wasn't sure if I should just get larger than 1.8L's.
Reason being the car was leaning out slightly stock fuel setup with vortech fmu and 190lph pump. Wanted to see how different injectors would result. Same setup has been on the car for 2 years and no issues.

where are you lean up top? on midrange tip in? please elaborate as to what you are experiencing. Notice my numbers are given 10 psi of boost to raise the Fuel pressure to 100 psi given 5-6 psi you have enough fuel for 200 whp still given a 10-1 disk or a little more given a 12-1 stock greddy disk but please tell us where you are lean this could be a base Fuel pressure issue a O2 clamp issue a dirty fuel filter etc. And tell us how you know you are lean as well.

I didn't feel like being a dick and starting a new thread, I plan on 9:1 forged internals, gt2860, valve springs for raised rpm, deshrouded valves, a slight polishing of the head and aim for 19 to 20 psi to stay under the diypnp bar limit. How big injectors will I need? I was thinking 600, but I'm probably wrong.

I highly recommend the Fuel Injector Clinic 650cc EV14. They are so good, they idle better than the stock injectors. I can provide basemaps for these. If you need to go bigger, I can also provide basmaps for the 775cc and 850cc variants as well.

You can idle ID1000s at stoich. They probably have a better spray pattern than the factory injector does. The IDs are dynamically matched, so low-speed driveability and idle quality will be extremely good.
In general, all of the downsides of big injectors are no longer a concern with EV14 injectors. You can have one set of injectors that will idle stoich, pass emissions testing, exhibit perfect driveability, and then support 500+whp on stock fuel pressure.
