trying to find out what fmu to run. i have a b16a2 with a greddy kit on it. Cp pistons 9:1 compression and eagle rods.i want to run 10psi. what size vortech disk do i buy? my fuel system is all stock,besides 310 injecors. any suggestions are really appreciated. thanks.

 

So you ditching the blue box? Do you have an afc or something to turn down the fuel for those injectors? Most people run 12:1 or 10:1 but you must relize that a HIGH POWER fuel pump is req., With a 12:1 with 10 psi you will be 120 psi OVER the WOT psi setting. This is like 160-170 total psi, thats a **** load for a system that is only set up for up to like, 60 psi. A reg warblo will NOT cut it! I would also recomend NOT using the ones that come in the drag and revhard kits (the inline one). Warblo makes a HIGH POWER one that will get the job done, just make shure you get the right one. Aeromotive is the way to go if you want it done right the first time.

 

so i would need a high power walboro intank fuel pump and a 10:1 or 12:1 disc. yeah i am getting rid of the blue box. would i also need the vafc with the fmu?

 

with the right fuel pressures, you technically wouldnt need the vafc hack. actually if you were to use the hack, then you'd be better off upgrading to larger injectors and keeping a stock fuel pressure. if you're going to use an FMU though, yes, you'd need a higher power fuel pump.

 

which disk would i need then? the 10:1 or the 12:1? also would the walboro 255 work?

 

Good luck!!!! Hope this works for more than a month for ya......

 

The stock ecu will idle 310s with no problem....Done it before myself, not overly rich or anything like that, smooth idle and all..

 

[QUOTE=keebler65]you technically wouldnt need the vafc hack. [QUOTE]
I was NOT talking about the hack! Just hooked up the proper way, to the map senser. This is just so you can turn down the fuel a bit for those 310. If runing 10 psi I would say go with the 12:1 disk but be weary, this setup is not verry safe with out a proper tune and 10 psi is alot even with piston/rods with out a good tune. I would say get some 550 or something like that and hondata and get yourself a good tune before you ruin those pretty pistons..

Warblo make 3 diffrent pumps for us, a stock replacement, a preformance 210 or whatever (what most people use), and a HIGH POWER one that is capable of shooting to 150 psi in split-second. The high power one is a must if using an fmu.

 

so would i be safe runnig the fmu and the afc abd getting it tuned? cant afford hondata.
