I was wondering if the Ultimate Fuel system from the rx7store.net (http://www.rx7store.net/product_p/ultimatefuel.htm) was neccessary for my setup. I know it would provide plenty, but would it be overkill, would I be able to downtune it to what's neccesary. (changing the injector size in the pfc to a smaller size maybe?)

We also need to know the boost levels you want or plan to run.

 

oh yeah.. Around 12psi but plan on upgrading to single at some point. And thought to go ahead and upgrade the fuel system now.

 

wow that is overkill for your setup but if your going single turbo than it would be ok. I would rather have to much fuel than not enough.

 

You can run 12 PSI on the stock fuel system.

 

And if that isn't enough, then you can get the secondaries bored out to 1300cc like many others and reuse the stock rails, lines etc. Works wonderfully well, simple to install and is very cost effective.
