I have a 93 FD with Greddy FMIC, HKS Racing suction Intake, DP, MP, Cat, Greddy pulley kit, Apex PFC. What type of fuel upgrades should I get? Injectors? Fuel Rail, Fuel pump? etc. I am looking at probably running a single soon but want to get the fuel out of the way. What would be good? https://www.nopistons.com/forums/pub...IR#>/smile.png

larger pump... and larger injectors(you'll need a new rail to fit them) maybe 1600cc for the secondaries

give keith a shout, he will hook you up.



rxrotary2_7 is his forum name. He makes kits for the FD.



Tell him bobby sent you https://www.nopistons.com/forums/pub...IR#>/smile.png

keith's web page is www.kgparts.com

But what size injectors.



Primary??

Secondary???



what fuel pump would be good to support around 400hp?



I was thinking of running 850 Primary, 1300 or 1600 secondary



And was going to use a twin turbo supra fuel pump, or hks fuel pump.

You can keep the 550 primarys. Go with 1600 secondarys. That is what i did. Keith sold me the 1600's.



I am running dual Walbro fuel pumps and plan to push 400whp...one would suffice.

400hp fuel system is easy to build, and not too expensive. here is what I did, no problems 1 year later



send your primaries out to be cleaned and balanced. get a rail and 1600 secondaries. an aeromotive fuel pressure regulator, and a walbro pump. thats it. done https://www.nopistons.com/forums/pub...IR#>/bigok.gif
