I did a search and didn't find any answers. I have a B16 that I am planning to run higher boost with (somewhere around 18PSI). I will be using the Zdyne Gold ecu and I will be adding a small amount of Nitrous just to spool the turbo (track use only) otherwise I will be running about 10psi on the street. Just wondering if my 450cc injectors will do or should I upgrade to higher cc injectors. Any help would be great.

Thanks!

What size turbocharger, what else do you have, etc.? With that information you will get better answers.

@ 18psi you'll be pushing those 450's to the limit. Go with some 550's or higher.

I have a Turbonetics T3T04E .63AR

Do you think 750's would be overkill?

I don't think they will be over kill. What are your HP goals? I went with MSD 72 lb/hr (756cc) injectors. Larger than I needed but leaves room for more power.

I'm not even sure what horse power I will get. The motor is fully built so it can withstand the higher boost. Any rough ideas what HP I'll get at around 18psi?

id run 550s...and an AFC theyll work fine together
