I was going to buy a 255lph fuel pump but i was wondeing if i could also buy an evo fuel pump will it work just as well? Thanks guys

do you have much mods to support it?

 

That's what I was thinking about ^
Would it work without major issues on a Lancer without fuel managment???

 

What would be good supporting mods? I've also wondered this and I have header, bored IM, bored fuel rail, custom exhaust. I'll be adding a larger TB and FPR as well.

I found this thread^

 

if everything goes right i will be going turbo soon so ill need a bigger fuel pump to support that. I will be getting a 12:1 fpr also but as far as ecu i wasnt planing on anything right now because i am only planning to go to 6lbs of boost.

 

thanks for the thread that cleared up some questions but i wasnt planning to put it on until i boosted anyways. will the evo fuel pump be too big or should i look for a cheap 1 or 2 g eclipse fuel pump?

 

Just get 190lph

 

The Evo pump is more comparable to the Walbro 190. And both the Evo's and the 190 are quieter than the 255 as well. Both should be good enough for any N/A mods, and modest turbos. The 255 is overkill unless you're going 250+whp.

 

thanks gunshin btw does any body know how much lph the evo pump is just curious

 

why does the rrm stg 2 come with a 255 HP then. remember it is better to have too much fuel then not enough.

by modest turbo's u mean how much psi?

always plan ahead, if u r planning more than 4-6 psi, eventually ur gonna need a bigger pump

 

the stage 2 comes with a 255 because its a bigger turbo.

 

The 255's are LOUD. Constant whine in key-on and while running (though you really only hear it while idling). On the down side it may be overkill, but on the plus side you won't be needing to upgrade again. What's the difference in cost? The 255's are around $100 shipped. At that price I didn't wanna bother getting less.

 

When I said the Evo's was comparable to the 190, I meant almost identical.

I would assume the RRM kit uses the 255 pump to simplify the kit. With that much flow injector upgrading could be postponed. Or, simply because most people, namely DSM's (RRE's heritage), just skip right over the 190.

Fuel delivery is a concert with the injectors, FPR, and pump the instruments. You can exploit one instrument or the other to arrive at the same number of ticket sales.
