S5 N/A streetport w/stock 460's?
I’m thinking about a large streetport and wonder if the stock injectors will suffice or if I need to upgrade. If I go with bigger injectors, do I need to go stand alone or will the stock ECU work?
Basically, will the streetport with stock injectors, ECU, and fuel pump be worth the effort?
Thanks,

The stock injectors are plenty for a streetported NA. The stock NA ECU runs super rich by today's standards. Get a streetport, keep the stock injectors and ECU. Get a SAFC and get it tuned. You will STILL need to tune fuel down to make more power. It is tuned that rich stock.

I have an 86 N/A with a streetport. Everything else is stock but for a K&N intake filter... my narrowband O2 sensor reports a good rich mixture all the way up to redline, with a 1/2 sec or so lean spot at the 3800 rpm point, but no physically discernable hesitation.
If you are going to the trouble of building up an engine with a streetport, I would recommend sending the stock injectors out for a professional cleaning at the same time.
