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)

      Leaking Rear Subframe Bushing?

      Perfect, I'll get to it this winter then at the same time as I weld on my anti squat kit.

      R32 only blows hot air

      By SeanR32GtSt · Posted

      Alright so my 32 only has one temperature no matter what degree you set it to. I’ve tried disconnecting the servo motor arm and moving it either direction and got no change. I’ve fixed the leak in my AC and re charged it and with it on and clutch engaged it still blows hot even though the low pressure pipe going to the firewall is ice cold. Both heater core hoses are hot while running as well. Diagnostic code showed 24 for intake air temperature sensor. Anybody got any ideas?

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By GTSBoy · Posted

      I said Garrett style. Not Garrett genuine. And something in the G30 550 range is what you want. Not those pokey little old fashioned T28 sized things. The intake ports in the head are small. There is little benefit in fattening up the runners and leaving ths actual ports small. Just run what you've got. And on the subject of Nistune vs Haltech etc..... You know you can control the transmission with decent standalone ECUs these days, right? No need to keep any of that old Nissan bullshit. Don't get me wrong - I use Nistune on my Neo. But it is a DET, so the number of bodges and workarounds I had to do to make it work in a chassis without ABS, TCS, etc, is quite small compared to the herniated arsehole you will have trying to make it work on a motor that doesn't have some of the things that the turbo ECU wants to see. Just easier to bite the bullet and go aftermarket outright.

      Hmm. Only when the f**king thing is actually working. Still can't find the leak. And that's with dye being put in the last 3 times!
