450+ but tq numbers need to stay around 350 and come in at a high rom like 4k. With that setup the motor will stay happy. Any lower instant tq or higher that's where it becomes dangerousOriginally Posted by Hermin

got me a turboxs stevejohns tune! this thing is sick!
got the 750cc injectors
this car is pretty fast lol
MORE FUEL DRAMA!
so my story begins with my aeromotive style FPR. it wasn't bad just I needed to go lower than 40 psi of fuel. the aeromotive style I had, had a set base pressure of 40-75. so I couldn't go any lower. so I bought a AEM FPR because it started at 20 and could go as high as the fuel pump could flow.
here some pics.
here it is all hooked up
now heres where the problem start. after installing the AEM I still could not get lower that 40lbs. needles to say I was pissed. so that's when I called William at PRW. I explained the whole situation. he instantly knew the solution. so I thought I would share It here.
this piece is the part you will need to modify. its the part where the FPR delete sits. its also how the gets syphoned from the other side of the fuel tank.
now if you look in the picture you can see the tiny hole that the fuel has to go through to go back into the tank. see how small that hole is? basically what happening is that fuel can not get through that hole fast enough. causing a back up fuel in that fuel return line. that fuel not getting through is making the FPR not to be adjustable lower. now it not only causes problems for fuel pressure but im almost willing to be that the FPR was not acting like a 1:1 fuel ratio. meaning. for every pound of boost im making, it gains a pound of fuel pressure. if that does not rise you will run lean.
now heres the issue. BBB drilled his hole too big. so now the gas wont syphon from the passenger side tank. he doesn't drive the car that often so its not a huge issue for him. but for me as its my daily its a must for me. so I measured the hole. and the FACTORY hole size is a 1/16 hole. I used my drill bits to figure this out. it was a nice up and down snug fit. so I went one drill bit size up. I used at 5/64 drill bit. which is slightly bigger. now that did 2 things for me. one allowed more fuel to flow out. second help me have a more accurate 1:1 ratio.
after I drilled the hole I was able to lower my FPR to 25lbs now. that may be a good sign since its suppose to lower to 20. because hopefully the hole is still small enough to syphon the gas from the other side of the tank. I will have to let you know in about a week if it did or not lol.
heres the hole drilled. as you can see not much bigger.
heres the pressure lowest it would almost go.
I now have it raised to 30psi. so by my calculations it should be close to 50psi of fuel at 20lbs of boost.
oh and I bought a big tial blue spring that I will run with a small red spring to run off wastegate of 20lbs of boost. im not gunna use a boost controller. just wastegate pressure.
This is the most recent pic of it I guess. Taken at FD
Not feeling the "turbo xs" on the intercooler, but gorgeous car.This is the most recent pic of it I guess. Taken at FD
Nice. I'm sure 450/350 is fun and enough.
btw I'm the guy that owned your S14 haha
Did you buy it from me or bought it from somebody else, what happened to it? Do you know? I miss that car so much. Couldn't ask for a better setup and motor was perfect
