I have a RB25DET with PFC, GT30R, 040 fuel pump, 740cc injectors, stock fuel regulator.

my fuel pump is very noisy. it was brand new. its actually the 3RD brand new 040 i have had fitted to the vehicle and all have been very noisy.

it has been confirmed that the pump has been installed correctly.

when squeezing the fuel lines connecting to the stock fuel reg, the whingy pump goes quite, but after u release the lines, it goes noisy again.

the car coughs and splutters with anything more than half throttle, or pretty with any positive boost pressure.

i have looked and cant find any kinks in any fuel lines or anything like that, could there be an issue with the stock fuel regulator?

I have come to the conclusion that 040 fuel pumps cant possibly be so bad that 3 brand new ones can fail, so i am refusing to believe there is a fuel pump problem.

any thoughts?

cheers.

yes its been tuned. i have checked the pump filter and its pretty clear.

the car drives perfectly fine off boost, but as soon as you try and sting it, its coughs n splutters.

coilpack and ignition has been checked and is fine.

pump is still very noisy.

    • The spray cans were in the "Kiln" room whilst I was preping the parts,  so probably around 2 hours to get them warmed up, the kiln room has 3 small ovens running at 100°c, 3 medium sized ovens running 100°c, and the large one I used running at 80°c, the room itself was about 28°c, I also spent a bit of time taping up the parts in the room as well, and by the time I was done I would assume that the parts were around that 28°c As for power, I expect a couple of Killerwasps up high would be achievable with the current mods, I'm still running the MZR 2.0 intake and throttle body, and there is a slight mismatch with the 2.0 intake (smaller) and 2.5 intake ports (larger) on the head, this intake is matched and specifically designed to fix this issue with the ports mismatch, the throttle body is also a couple of mm larger, OEM is 65mm, the Bosch is 68mm In the end it will look "prettier" than the molded plastic thing that is the OEM MZR 2.0 intake As for the LSD, it's the OEM Torsen which works fine for what I use the car for, plus, basically no maintenance apart from the occasional oil change
    • I was at Tunehouse in Marrickville (great team over there really know their VR's) , and I spotted this Very clean R35.  
    • Mate , I have the same issue right now with the exhaust noise , if you can tell me what your local guy did , I'll talk to my guys and see if they can do the same. Power is good but it just too loud when put it down. 
    • The other trick I've found with wrinkle black is to put the can in hot water for a bit to warm the paint up, and to pre-heat whatever you're painting. It'll be interesting to see if you pick up any power with the intake, following with interest. Got a proper lsd for this?
