Has anyone every put the secondary injectors as the primarys???

I have 840cc primary injectors, with 1350cc secondary injectors...
Greddy fuel pressure regulator
walbro 255 lph fuel pump.


My problem is that this car floods, and sometimes wont even start. Spark plugs look wet, There are many mods on this car so i thought that the primary 850cc injectors would be okay, maybe i was wrong? Any thoughts or opinions would be appreciated.

Also i have power fc with commander...

Im am not sure if the injectors are even the problem with the car not starting, it could be someting else... but i need to know if primary 850cc injectors is even logical...

To clear up confusion, the car has great compression, all new vacuum hoses, no leaks, ran for a while, fouled the plays, hasnt started since... (weird? i think so...)

SEARCH and read the FAQ. Many people run the stock secondaries as primaries. The fuel rail has to be milled down for the injectors to fit properly without leaking.

The injector sizing and lag times must be set up correctly in the PFC as well.
