i realli dont want to go threw all the trouble of fitting a surge tank and all the lines im after some thing i can just bolt in and fit the problem

i wanna get out of this the most cheapest way i can as well

On the cheap? Here's my suggestions to save coin;

1. Use stock pump and dont go for big power

2. 044 intank, tune for 380 or so rwkw and be happy with that power

im running a 044 intank, using a efi v8 falcon fuel sock retrofitted to suit the bottom of the 044.

simple install and no issues with 5 ltrs in the tank around corners etc.

only way to do it IMHO.

note the clear fuel hose i have mounted around the pump absorbs all the vibration, so its very quiet.

i had my car on the dyno for a tune yesterday and when we got to 400kw it started running into problems with fuel

we had a fuel pressure + flow gauge connect to the car while we were tuning the flow doesnt drop at all but the fuel pressure goes from 40psi to 60psi and then just drops back down to 40 instead of going higher it just drops back to 40 and the car leans out so we neva got to finish the tuning

fuel system is pretty basic

bosch 023 (rated at 700hp) mounted intake

SARD 800cc injectors

HKS fuel reg

Fuel pump for sure. Stock rail is good for well over 400awkw (maybe more, but ive had a few RB26 in here pull well over 400 with no issues)

      RH9 R32 GTR Build Thread

      Out of curiosity, how do you cover up the inspection hole? Surely it doesn't sit open like that, right? With grime and dirt coming in and oil going out?

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything
