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 :)post-117959-0-92601700-1376206934_thumb.jpgpost-117959-0-42270900-1376206948_thumb.jpgpost-117959-0-76854400-1376206953_thumb.jpgpost-117959-0-72476100-1376206965_thumb.jpg

update,

Got my N1 pump from the sates, replaced the N1 gears with a billet set.

Managed to get my hands on a modified turbo outlet pipe, hopefully the baffles give me a nice little bit of response.

I'm hoping to get the most out of my little GTSS turbos.

Plans while the motor is out:

Fix the coolant passages in the head.

,Bearings and does anyone recommend further crank balancing? and how necessary is a nice harmonic balancer?

looking to limit revs to 8500rpm, cams are hks 264/8.7s

most other things should be pretty good since its such a new motor (touch wood)

Tomei sump baffles.

Im assuming that r32,33 and 34 exhausts are fairly similar and would fit either car? have a 3inch but am looking for a 3.5inch if anyone has one nearby (Newcastle)

Haha that's alright mate :) Ill definitely post some more pics up when I get a chance! I'm thinking of getting some ROTA grids for it and selling the koyas. Not sure what the max width I could go on the front wheels would be. But ill be happy with getting rid of these wheels and dropping my coilovers to a cop friendly but clean height :)

Yeah I know Koyas are better design but I'm not a big fan of 19s on my car. I'd rather a nice set of 18x9 ROTAs . They look good to me and I won't be jumpin ripple strips every day haha. It's mostly for looks. I might go with painting my 33GTR wheels black to start with
