If you run the ZZP kit as option 2 and dropping tank, there is no benefit to either OTTP or ZZP. Both function the same.

The OTTP kit is prettier and little easier since it comes with pressure gauge on regulator, and in the engine bay.

 

There is a thread on hpt forums on how to tune a return style.

 

Thanks for the info Wes. Thanks stiner and skatin, I do know that both gmsc and hpt are muchhhhh better places to get what you need.

 

I know this thread is a little old but i'm building my 2.2 up and i want around 360 to the wheels. Would the brfps be enough for me. I am going to be running e85 and 80s on the zzp turbo kit for the 2.4
Would the ottp return style even work on a 2.2? i think the fuel rail is different?
