As you all know.Boost = more fuel.
How can this be done.
FPR and bigger injectors?
There are limits with this solution and you reach them quickly.
Stand alone injection? Probably the best but exspensive

Additional injectors controlled by a boost switch? on off caracterics
difficult to get enough fuel at high boost without get to much at low boost.

Map fuelers? Probably the best solution at a resonable price
since they varys the amount of fuel depending on boost pressure.
One variant i have seen was capable to comntrol 4 additional injectors.

Since i need to get an complete engine at the junk yard too complete my new shortblock


This is a cut trougth pic of the stock manifold


The idea i got was too use the injectors and fuel rail from another engine.Bore holes for the injectors on the under side of the stock intake manifold,weld on fasteners from the fuelrail and control those 4 injectors with an Map Fueler:

This is a pic on how my idea will look



What do you guys think?

Ps the manifold are for an 2,0 i 16 Mazda engine but the idea should be possible too use on other engines too

 

People have been running secondary fuel rails and secondary injectors for a loooong time.

They typically put the rail a bit farther back than the stock rail, since there is a bunch of stuff in the way underneath the raill... in addition to the fact that you'd practically have to remove the manifold if you wanted to swap/service the injectors...

A setup with dual fuelrails should deliver enougth fuel for me so a injector swap would not ne nessecary.
Removing the injectors of other reason would probably never be nessecar
Those jap cars are as trouble free as any car can be.(driven jap for th last 14 years)
at last the 626 have not much stuff underneat the intake manifold.

 

The problem i see with this is not with the setup itself because it can work. But with the time and money you spend doing this, not to mention the headaches, you could've bought an aftermarket programmable ECU.

 

the new victor x manifold comes with secondary injector holes if you want it to right. and this would be just like the mf2 setup in the fmax kit also. just adding 2 440s for extra fuel. for the price of hondata i think it makes these kind of setups not worth doing.
