Hi all, just a little info about me
Name's Blake and Im stepping into the JDM world. I have been primarily focused on the ford 4L inline six, and while its a great platform for easy reliable power it was inevitable that the high revving nature of the Jap inline 6s would eventually take hold on me.
My daily driver is a 400rwkw 6sp auto xr6turbo.
My project is a turbo Ef falcon 5sp.
so now onto why I am here, I recently purchased an r34 GT4 from a mate, the car has been kitted out with anything retrievable from his wrecked 33 gtr.
-RB26, forged internals, nitto gaskets etc etc
not sure about oil pump but it does have an enlaged oil drain in the head.
HKS 264 cams
HKS cam gears
HKS GTSS twins
3inch catback with stock dumps (got dumps on the way)
Trust oil cooler
Fuel system:
Sard billet fuel rail
Turbosmart adj reg
sard 1000cc injectors
twin braided fuel pressure lines and single oversize return
twin intank walbro pumps with relays
Haltech platinum pro with EFLEX e85 sensor.
r33 gtr brembos
Koya r-1 245-30-19 fronts and 275-30-19 rears
r34 gtr rear wing
Basically the car got defected, my mate spent 8grand on the fuel system, ecu etc getting it all legit and passed emissions.
when it was time for the e85 power tune the tuner said he heard a noise and was worried about a spun bearing.
so I offered my mate 6k for the car and he regretfully said yes.
the car was fine to drive around with no rod knock.
however, on cold start only while the oil pressure light was one you would hear a series (maybe one seconds worth) of knocks
factory oil pressure guage seems to be semi retrarded so I fitted a mechanical autometer guage, 60psi at 4k cold but after the oil heated up the pressure was only 10psi at idle. I can hear a very slight knock so I have decided to pull the motor to avoid a potential for legs leaving the bed etc
Now I have done a fair amount of research on oil systems for the rb26. That doesn't make me an expert so I would like to list me plans and see what you all think.
Billet N1 pump $350
n1 housing $350??
ACL race series bearings
now I am unsure of whether It is really necessary to go for an extended sump or just the tomei baffles??
I plan on doing hill climbs, track days etc. the car wont be stripped out.
I already have the Oil drain in the head enlaged, I couldn't find receipts for which pump went in when it was rebuilt (3000km ago)
sump will be overfilled for track work. and if I can get away with only the baffles I will be much happier keeping the extra grand for other things
Im going to have a crack at removing the motor myself, looks like a PITA, rebuild it myself and go have fun
