my friend and i had a debate about running a walbro in a n/a engine. is it true it will be okay?

 

It will be fine. It's a waste of money and total overkill, but it'll be fine.

When I upgraded my fuel pump (on my NA build), I just got a stock Eclipse one (out of a turbo model, obviously). Had more flow than the stock Lancer one and cost way less than the Walbro.

 

What about a used Evo pump? are those compatible?

 

Yeah, that works too.

 

yup you will be fine. you wont run rich with a walbro due to the MAS.
