NEED HELP WITH NEW FUEL SET UP (RICKY!)

[otightitzjim]

HEY GUYS. BEEN SUPER BUSY AND SAVING UP FOR A NEW FUEL SET UP ON MY RB25 S14 TO ACTUALLY BE ABLE TO MAX THIS TURBO OUT. THE CURRENT SET UP MAXED OUT MY SIDEFEED 740's WITH THE INTANK PUMP WALBRO AT 18 PSI MAKING 506 WHP ON THE DYNOJET. I WANNA GO WITH A FUEL CELL WITH AN EXTERNAL PUMP. PLEASE LET ME KNOW WHAT YOU GUYS THINK. WHICH SIZE INJECTORS SHOULD I USE AND PUMP SET UP. THANKS.

i wouldnt bother putting in a fuel cell, it is a street car right?

I would either put in another pump inline such as the bosch 044 ( ive done this and made over 600whp) which will max your turbo out...

Or i would take out the walbro and put in twin bosch 044's and never worry about fuel again... make a custom pickup and have the pumps mounted outside the tank in parallel

were you unable to rev higher due to fueling? cause that thing wasnt ready to stop making power at all!! sick power on pump gas i would assume

I'm very surprised you made that kind of power on that turbo. That's pretty impressive.

You aren't running out of injector (unless you are running e85) you are running out of fuel pump. Give it enough fuel pump and you'll get another 100rwhp+ worth out of the injectors at stock fuel pressure. Lastly, at your current level, that Z32 MAF should be about pegged. What is your MAF voltage looking like? Time to think about something bigger. Again, amazing numbers for that turbo

I guess i was honestly thinking of going fuel cell, external pump, top feed 1000s, and going with a bigger turbo. Something like a gt35 or gt37. So if i run the dual 044s, would they be fine as far as them both being on at the same time the whole time my car runs and idles? How about as far as my fuel lines? Can i keep the same ones? I was always thinking of going dual in tanks, but i figured if i upgrade why not just go bigger and better. CJMARTZ im honestly not too sure about my MAf voltage, the car is currently in california, while im here in MARYLAND. Im having a friend of mine do the fuel set up for me out there before i ship it out here. And FLATRATE, yes i was unable to rev higher nor boost any higher because we were starting to see knock after 18psi because of fuel pressure drop. Im very curious to see how much hp she'll give me maxing out the turbo effiently. This was all on 91 pump gas. I was very amazed on those numbers. heres a vid wit her on 16 psi. the run was on toyo r1rs 265s. cant get em to hook up. thanks guys.

the 3082r is a 30r turbine with a 35r compressor... i dont see why those numbers are so impressive i mean yes there good for that boost level but there is still plenty left in that turbo... you should be able to make at least 560-575whp... maybe even 600... im really surprised the torque is holding so well for having such a small turbine.. dont bother with a 35R you already have a 61mm compressor either go 6262 billet wheel or 67mm... just thinking out loud

they will be fine as long as the return line is large enough, which i think it is.. idle shouldnt be effected from the fuel pumps... altho going to a 1000cc injector might depending on what brand you get.. injector dynamics are NICE injectors and will idle like stock.. i have FIC 1100's in my other car and it idles like a dream with a 60psi base fuel pressure
