fuel pump support question?

[spidy3]

Does anyone know up to what injector size a walbro 190 can supply fuel to? I cant find any information on that or how much psi from turbo it can supply fuel for. Im planning on running a evoIII 16g @ about 20-23psi with denso 660's. I have the main mods done, intake, turbo back exhaust, gm maf & maf-t. ported head & exhaust mani., mbc. and some others that dont really pertain to question or fuel supply. Any and all info is helpful

Thanks,

Dom

Ran that setup last year with a 190 on the stock wire, it was fine.

I now have a 50 trim at 22psi, still on the stock wiring and it's still fine.

A 190 pump is more than enough for 90% of the people out there.
