Fuel injector question

[Dllrd23]

I’ve rear through most of the posts on this subject and thought I would get the group’s opinion. I have a 2.7L 5 chain engine out of a 01 Boxster going in a 1999 replacing a 2.5L. I have kept the original intake crossover and used it as the front so that I could retain the cable driven throttle body. The intake is from the 2.7. Rear crossover without butterfly valve is retained in the rear position. For the fuel rail I used a 3.4L rail because it bolts up directly and is a return type. What fuel injector do you recommend? Still running the stick computer with no tune (yet). I don’t think I can run the 2.7l as they go on a returnless system. That leaves me with the 2.5 (no specs found) or the 3.4 injectors? What is your opinion?

Can you post pics of the different injectors you are looking at installing? Or even post the Bosch part numbers in question. Maybe someone other than me will reply if you post more details.
