Ok well i wanted to know how much hp i can get out of walbro 255 fuel pump and stock line from my 98 civic. I have a y8 block with z6 crank,eagle rods, srp pistons, stock head with isky vavle springs. it also has 2in intercooler piping from turbo to intercooler and 2.5in piping from intercooler to tb, running a custom turbo manifold, 50trim turbonetics turbo, turbonetics wastegate, hks blowoff valve, saturated rc 750cc injectors, 2.5in downpipe connected to 2.5in exhuast pipe and out throw a greddy evo 2 muffler. It will also be tuned off of aem ems. Sowith all that said how much power do you think i can get with this setup?

hatche1

can someone help me

You can make more power with that walbro then that 50trim turbo can make and more power then your injectors can handle. Your setup if properly setup would probably max out at about 400whp

hatche1

thanks this is the exact help i needed. also what kind of gas would i have to run if i wanted to run 400hp?

92redhatch

With a good tuner on that sohc pump gas. Or a better option would be e85 but I don't know if your injectors would be able to handle 400whp on e85

hatche1

well thanks for the help.

No problem.

honestly, for your setup an aem is absolute overkill

92redhatch

Overkill on an ems is not a baD thing

ya i had kind of figured that but then i already had bought the ems and no one seems to want to buy it from me so i could go a different route. so i guess i'm just going to use it and see what happens.

okay so i was talking to friend today and i had asked him what fuel pump he was running on his built gsr with 13ibs of boost and he said he has been running the STOCK FUEL PUMP and is making 305whp to the wheel on a mustang dyno. so with that said do you think my stock fuel pump in my ek hatch will hold up on my ek hatch?

92redhatch

Don't cheap it out just spend $100 on a walbro 255hp. Doyou want to spend double the money to rent a dyno?

well, you should really run what your local tuner is comfortable with, but like i said. you could use the money from the aem to get a chipped/or s300 p28 and use the rest of the money elsewhere in your build, like a fuel pump

Correct me if I'm wrong but from what my tuner told me doesn't the stock pump max out at around 230-240hp?

Kinda wondering the same thing, I wasnt getting enough fuel during the tuning and im only running around 290WHP. ( yes I put in a walbro 255 ) And that solved the problem

hatche1

well running a stock fuel pump was told to me by a friend( not my tuner) who still has the stock fuel pump in his gsr and is running 305 whp on a mustang dyno.

hatche1

well for right now i'm just going to go with a chipped ecu and get it street tuned on ectune by one tuner and then when i come up with $450 i'm going to get another tuner( cause to tuner thats going to street tun my car doesn't know how to tune ems) to dyno tune my car on aem ems.

sma99honcivsi

If your tuner dosent know how to tune with ems i would not let him touch my car find another tuner...

hatche1

lol well one of my tuners knows how to tune on ectune and my other tuner knows how to tune on ems. i'm only going to be tuned on ectune for the mean time so that way i can start driving my hatch on boost but later on i'm going to get it tuned on ems so that way i can tun my car with boost by gear.
