Evo3 Big 16G, what psi?

[eclipsegst3131]

currently i have a fully rebuilt motor, only has a cometic head gasket and eliminated balance shafts. i have an injen intake, greaddy ic pipes and rs bov, full 3" exhaust and an evo 3 b16g turbo. question is, how much psi should i be running with the stock fuel pump and injectors 'safely'. i want to do injectors obviously, what size should i get, i'm looking at making about 320whp. also, im getting a walbro fuel 190 fuel pump. what psi would i be able to run when i get the fuel upgrades in, and is there anything else i should do? thanks for any and all help!

Sup meng......Im trying to do about the same..... i think if you set it to around 12-14 it should be okay, well at least thats what i was told by Mike from RRE.

how about you get a logger and see when/if the car knocks

, cuz i'm cheap...i need one i know, but how much could i run with the fuel mods i've done, or how much has anyone heard of people running. thanks for any help.

i was told 15 psi on stock fuel. go with at least 650 injectors. i got the evo3 680 injectors, a walbro 190, safc2, and a pocketlogger. all of which are a must in my opinion.

evo3, stock injectors, 190lph, no logger = 15psi good game. Still 10x better than a t-25@15psi

when u get a logger and check knocks/timing, then maybe u can go up.

Hey man, bottom line is you got some sweet gear under that hood . . . don't ruin your week/month by blowing a head gasket or w/e

You shouldnt have upgraded turbos if you are to "cheap" to get a logger. Things arent gonna be cheap when the engine starts detonating.

Probably better off with a fpt28 without a cat. I havn't heard about those creeping much.

I run 18 all day (miost a 1G BOV will take) and Im fine. I have 550 cc injectors though. Everything else is completly stock. And I get no knock!

You should definetly go with the higher flowing pump (opinion) to make sure you're adequately pumping enough. I know a lot of people say "it's okay, it flows more then enough" Just a little added security.
