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

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
