Im upgrading the fuel system and I want to make it be able to handle the power. I want to upgrade only the secondaries but what size should I get to handle 350hp?? Will 720cc Secondaries be good enough or do I need larger?? Any help is great.

Thanks John.

 

720s in the secondaries, A walbro (or FD fuel pump), Super AFC (or FC of your choice), FCD and youll be good in the fuel dept.

 

4x720's are needed - just a pair of 720's in the secondaries is not enough, unless you do some fancy fuel rail pressure raising...

Go old school and use a Malpassi

 

Thanks for the help all. i appreciate it.

 

hey another guestion. do the 720cc injectors from say nippondenso or greddy fit in the stock locations for primary and secondary. or do they require some kind of modification or custom fuel rail.
