I am looking to get a set of 720cc secondaries. My question is what kind, peak and hold or saturated and top feed or what? I have a s5 turbo swap in my vert with a streetport, fmic, apexi neo, greddy boost controller and thats pretty much it. Just wondering thanks

 

well since you're running an s5 swap, I presume you already have a high impedance system, so it would be easiest to run saturated 2ndaries. However, if you were running a standalone, I would recommend using peak and hold for primaries and secondaries to get the most efficiency out of that size injector.

 

RC engineering sells a high-imp 750cc injector
